[Rails] trouble in storing dates from localized form text fields...

2012-01-28T06:29:00.001-08:00

[Rails 3.1.3 / ruby 1.9.2 ]

I am trying to manage localized dates and I don't actually understand
how it's managed w Rails 3.1 ... I thought there was no more issues w
I18n..

my locale is defined : I18n.locale => :fr
I am using a localized version of jQuery DatePicker , so it displays
selected dates in the text field like : 01/02/2012 (Feb first )
i.e. ( in generated html):
<input id="start_shooting_date" class="text
hasDatepicker" type="text" value="01/02/2012" name="project[start_shooting_date]">

in my Project model , date validations are OK, then I store the
updated project
@project.update_attributes(params[:project])

and I get stored in the DB : start_shooting_date: "2012-01-02
00:00:00" (Jan 2nd) rather than "2012-02-01 00:00:00" ( Feb
first )

I'll appreciated your feedback ...

I defined in environment.rb ( don't know if necessary.. for input .
but it seems to be for output, or is it redundant with defaults .yml
files ?)
# if locale french
Date::DATE_FORMATS.merge!( :default => "%d/%m/%Y" )

I also defined the I18n default format in the .yml files

fr:
date:
formats:
default: "%d/%m/%Y"
short: "%e %b"
long: "%e %B %Y"
full: "%A %d %B %Y"
time:
formats:
default: "%d %B %Y %H:%M:%S"
short: "%d %b %H:%M"
long: "%A %d %B %Y %H:%M"
am: 'am'
pm: 'pm'

en:
date:
formats:
default: "%Y-%m-%d"
short: "%b %d"
long: "%B %d, %Y"
full: "%A %B %d, %Y"
time:
formats:
default: "%a, %d %b %Y %H:%M:%S %z"
short: "%d %b %H:%M"
long: "%B %d, %Y %H:%M"
am: "am"
pm: "pm"

[Rails] Re: Problem with Asset Pipeline

2012-01-28T02:05:00.001-08:00

Today I tried to replace jammit with asset pipeline in 3.1 again. This
time I got much further, the app could server JS and images correctly
from assets/ folder.

But I was not able to make the CSS right. I used stylesheet_link_tag,
but it kept serving CSS from /stylesheets/ instead of /assets/. Anyone
has an idea about this problem?

Thanks!

You have tried to access a method encrypted_password on the Signin
class. Either the signins table does not have a column of that name,
or you are calling encrypted_password on the wrong class type.

If you are using ruby 1.9.1 then upgrade to 1.9.2 (or 1.9.3 though
maybe it is still a bit new) or go back to 1.8.7
1.9.1 did not play well with Rails

Re: [Rails] password encryption is not working..

you are not declared 'encrypted_password'' variable. so first declared that variable in model and use it.

[Rails] Re: Redirecting to create new page with input

2012-01-27T20:14:00.001-08:00

Thanks for your explanation. It is exactly what I wanted.

in search.html.erb, I added

<%= link_to('RegisterThisMovie', {:controller => 'video', :action =>
'new', :url => y }) %>

'y' contains the url of the movie after executing the search.

in video_controller.rb, I added

def new
@video = Video.new
@video.url = params[:url] #<---HERE
respond_to do |format|
format.html # new.html.erb
format.json { render json: @video }
end
end

then it worked fine!
Thanks for your help.

I`m writting sinatra app and i would like to setup encryption in Warden

module Encryptors
class Md5 < Base
def self.digest(password, stretches, salt, pepper)
str = [password].flatten.compact.join
Digest::MD5.hexdigest(Digest::MD5.hexdigest(str))
end

[Rails] ActionMailer and Ruby SMTP causing a segmentation fault!

2012-01-27T15:14:00.001-08:00

I just activated Devise' :confirmable option in my User model. As Devise tries to send out the confirmation-link email I get a segmentation-fault error in Ruby's SMTP library:

... lib/ruby/1.9.1/net/smtp.rb:583: [BUG] Segmentation fault

My config/environments/development.rb file has the following:

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

My /config/initializers/setup_mail.rb file:

ActionMailer::Base.smtp_settings = {
  :address              => "smtp.gmail.com",
  :port                 => 587,
  :domain               => "mydomain.com",
  :user_name            => "[redacted]",
  :password             => "[redacted]",
  :authentication       => "plain",
  :enable_starttls_auto => true
}
ActionMailer::Base.default_url_options[:host] = "localhost:3000"

The relevant code in smtp.rb   are these two methods:

def ssl_socket(socket, context)
  OpenSSL::SSL::SSLSocket.new socket, context
end

def tlsconnect(s)
  verified = false
  s = ssl_socket(s, @ssl_context)
  logging "TLS connection started"
  s.sync_close = true
  s.connect  # THIS IS LINE 583
  if @ssl_context.verify_mode != OpenSSL::SSL::VERIFY_NONE
    s.post_connection_check(@address)
  end
  verified = true
  s
ensure
  s.close unless verified
end

I've tried setting :enable_starttls_auto to false.  I don't get a segmentation fault, but no mail goes out either.  I can get a session going with the gmail smtp host via the command line.  I'm running on the latest version of Mac OS.

Never had to debug a segmentation fault before.  Pretty intimidating.  Any thoughts, ideas, approaches?

Re: [Rails] Re: Polymorphic association

2012-01-27T13:34:00.001-08:00

Don't let that daunt you. I was in the same boat as you were not long ago. I'll tell you what I did:

Completed http://ruby.railstutorial.org/ -- twice! It does an awesome job of explaining things.
Rails for Zombies I, a screen cast series on codeschool.com (I think--you'll have to google it).
Rails Casts
Rails Guides

I actually started with Programming Ruby 1.9, the Pragmatic Programmers Guide. I didn't finish it. I read enough to get the basics of Ruby syntax. Knowing the Ruby syntax is essential since, to me, it looked nothing like anything I've seen before. Bracket were often omitted, and so were semi-colons, blocks, etc... understanding the syntax made understanding easier.

After getting through 200 pages, I switched to Agile Web Development with Rails 4th Ed. Frankly, I thought it was a waste of money at that point. It just told you to do stuff without explaining much of what you were doing. Especially when it came to testing. I quit and switched to Rails Tutorial. I don't think it's beginner friendly.Rails Tutorial I thought was brilliant. But it was hard to follow because of some issues. There was no mention that Heroku did not support SQLite for example. But the book does an awesome job of explaining the basics. Read it carefully. And it's free.

I'm planning on Reading Rails AntiPatterns and The Rails 3 Way next...

When you say you have read the rails tutorial book is that the one
that goes with railstutorial.org? If so then reading it is not
enough. Work right through it doing all the examples and so on. Make
sure you understand every line of code. You may think that the
application it develops is not what you want but that does not matter,
it will show you a wide range of techniques. Make sure that you have
installed the version of rails that matches that used by any tutorial
you use.

From what you have written so far, it seems like you want a standard has_many and belongs_to association.

User has_many :posts will let you do @user.posts, and a Post belongs_to :user will let you do post.user. If you want customize the name of the association, as in post.author, then I think you need to use the :class_name

I read the Rails Tutorial book, but I does not teach anything related to customizing that much, thats why I'm constantly search google and asking questions here (when I don't find it on google).

Just visit amazon.com and type rails books and you'll have a great selection to choose from. Also, try this, which I started with: http://ruby.railstutorial.org/chapters/static-pages --avoid the shortcuts and don't rush. It pays off in the end.

The problem sometimes comes in deciding what is business logic and what is not.

Hey, I just manage to do what I wanted, but I had to add a owner_type column on my Posts migration with the content:

:owner_type => 'User'

Thanks for everyone, and is there a better way than saving another varchar(255) to my database?

Re: [Rails] Re: Polymorphic association

2012-01-27T10:39:00.001-08:00

I did, also, it gives me the error: "SQLite3::SQLException: no such column: protests.owner_type:"

I don't know if CSV has the option, but FasterCSV has an option you can pass to inform it that the first line is the header row and it will skip it automatically...

It looks like you're describing a standard has_many relationship. Are
you implying that Post will be extended to be different classes?

[Rails] Polymorphic association

2012-01-27T08:44:00.001-08:00

Hi, I want to do a polymorphic association like that:

class User

has_many :my_posts, :as => :owner

end

class Post

belongs_to, :owner, :polymorphic => true

end

meaning that I want to do:

@user = User.new

@user.my_posts (and that would return Post objects)

also

@post = Post.new

@post.owner (this would return a User object)

How can I do that?

2012-01-27T08:41:00.001-08:00

The problem is that I want to redirect to the same url (meaning, I don't want to redirect, just want to go to the same route, and it will render a different view because I did this in the view with an "if user_sign_in?")

I think you need to re-think how this login will work. If you're trying to log in on a page, and then show that same page again after the user has logged in, what will trigger to the authentication system that the login is necessary?

Devise is abstracted around solving this particular problem: User arrives at a page that she needs to be authenticated in order to see. She is redirected to a login page, authenticates, and then is redirected back to the originally requested page. If you're not trying to do that, then you have to add on to that behavior, not replace it, or you won't have much benefit to using this framework.

Try this. Follow the examples (RailsCast has a very nice treatment of Devise, goes into all the nooks and crannies in two parts) and build the normal authentication system. Be sure to set a root page that is not the login path. Then add a *login form* to your root page (and optionally hide it if the user is logged in) using render partial in your view. This will be used to authenticate people who *want to* sign in before they are *required to* sign in.

Re: [Rails] Devise - Sign up and sign in at same view

2012-01-27T06:45:00.000-08:00

It didn't work, when I do

devise_for :users do

root :to => "devise/sessions#new"

end

because I want to log in in the root url and then remain there, but with a different rendering (logic is inside the new view of users/sessions)

It keeps trying to redirect to the root url again and again, giving a message "Too many redirects occur..."

What should I do?

Thanks in advance

Oh! Okay. That's a bit more tedious code. What you can do then is
have the errors attach to the specific fields, and check for them when
displaying each field. I think there are some standard ways to do
this, but I don't recall offhand where to find examples and
instructions. Google is your friend. IIRC, the default stuff will at
least put a red box around the specific fields, using CSS....

Let me see if I understand correctly what you want. When you say
"send the URL" you don't mean that the user should be sent to that
page (whether in the same tab or window, or a new one), but simply
that that should be the pre-filled value on the "New Video" page.
Right?

There may be a more "Railsy" way to do this, but what comes to my mind is:

Have the links link to #new, but add a parameter called something like
video_url. You could make it a URL parameter, so that rather than
going to myvideostore.com/videos/new, you'd go to
myvideostore.com/videos/new?video_url=http://youtube.com?watch=abc123
or whatever. (Actually the video_url should be url-encoded, but I
think Rails will handle that for you.) To do that, I think you can
pass a hash of params to link_to, or IWCTW you can tack it on
manually.

Or you can make them form params, so they don't show up and look ugly
on the URL after the user clicks. Make a tiny form for each one.
Have the URL as a hidden field. Have the link submit the form, to the
videos_controller#new.

Either way, in the controller, after you call Video.new, set the
object's url to params[:video_url]. Then when you display it, the
value should show up just fine.

Let us know how that works for you.

Disclaimer: I haven't tried ActiveAdmin, so this is just about Rails in general.

I did something sorta like this in The Decider. The Edit Decision
view includes editable display of each Decision's Factors,
Alternatives, and Rankings. (Which should have been called Ratings
but that's another story.) These are each separate models. You can
use the app yourself at http://thedecider.herokuapp.com and see the
code at https://github.com/davearonson/thedecider/.

To do like I did, just have your Customer model say it accepts nested
attributes for users, and in your order view, use fields_for when
displaying the Users. IIRC, that was all I had to do! (Nitpick: I
don't understand why a Customer would be/have two Users. Are you sure
your model shouldn't be Shipment or Order or ServiceCall or something
like that?)

I couldn't find any good clear online documentation of how this works
and what you need to do. By experimenting, I found that Rails will
take care of the rest with its wonderful behind-the-scenes magic of
tagging things with appropriate name and id attributes in the HTML,
and interpreting those when returned, so you pretty much don't need to
do *anything*! You *can* define an attributes= method if you want,
but chances are very good that what Rails will do by default is
exactly what you want, and any attempt to provide that yourself will
just mean having write a lot of tedious code.

if anyone can help me with a test problem. I need to test if my model
"Procedure" is linked to the workflow. If not, the system must
acknowledge an error. Below is the code that is in the file test \ unit
\ procedure_test.rb.

require 'test_helper'

class ProcedureTest < ActiveSupport::TestCase
should belong_to :workflow
should has_many :tasks, :through => :workflow
#should has_one :timeline
#should has_many :timeline_items, :through => :timeline
end

The shoul "belong_to" is working normally but when running "rake test"
appears the following error:

$ Rake test
/ home / guilhermec / iba_jornais / test / unit / procedure_test.rb: 5:
in `': undefined method `has_many' for ProcedureTest:Class

That means that @banner.photo is nil. Add code to your view to test

I think it's cool to have job posts here... as long as they're

constantly leave you wondering if you're in the level they're
searching for, if it's opening for remote and the like...since this is
a little bit more of an intimist place most people would get annoyed
by Ctrl+c,Ctrl+v generic openings descriptions that fail to give us
the info we would need to know if we're interested or not...

the talk here is supposed to be coder-to-coder I guess..

[Rails] Redirecting to create new page with input

2012-01-26T21:54:00.001-08:00

Rails 3.1.3

I believe this is a very very fundamental question, but since I am new
to Rails, it's more productive to ask someone to point out what I need
to do.

Say, I have a search method that generates a list of youtube videos. I
have completed this part.
And also, I have set up a database, Video, whose fields are video_title
and URL.

I need to place a button to each of these video outcomes.
My question is :

when clicking the button, how can I automatically send the URL of the
corresponding video and simultaneously redirect to NEW page where users
can create a new video entry??? In other words, in the creating new
page, the URL (and hopefully the video_title) is to be already filled
out.

I am thinking that I need to set "routes.rb" so that redirecting can
take
some values together. But routing is very confusing to me so far.

Could anyone help me out?

Oh of course, how could I forget -- last year, Puppet Labs was trying
to convince me to consider moving to Portland! Very nice city
(visited there last summer), but I don't want to move. :-) New
Relic's also there, and a fair assortment of startups. Still fewer

The main tweak I'd make to that is to put the location earlier, and
maybe be a bit terser. Some email clients have very little room for
the Subject in a listing. Also be sure to include if remote is OK,
e.g., "[JOB] NYC/Remote 2 RoR devs w/ 2+ yrs exp for gaming startup".

TL;DR

* broadcasting is inefficient

* anyone cares for a "community job site" ??

* I object to massive job spam on this list

Broadcasting _all_ jobs to _all_ readers seems horrendously inefficient.

I already got nervous with the recent few "job" announcements that

where totally irrelevant for me (and probably 90% of the readers).

And indeed, the worst of it is, you need to read half of the text to figure

out it is in NY, Berlin or SFO ...

I seems so much more efficient if you at least one can filter on a few

basic criteria like:

* location of work (that is _not_ location of employer, client or recruiter)

* a few keywords/tags (front-end, back-end, javascript, ...)

* recommendations (for the job/employer, I mean)

I spent 6 months on my own money setting up a free job job site (that was

2008, my first Rails project), but no real success (technically, it was great,

it had 1,000 high-tech/start-up jobs that where otherwise not publicized that

I scraped from 100 high-tech companies' job sites, around university of

Leuven in Belgium ; http://allejobsinleuven.be in case anybody cares).

Recently, I picked up a similar idea again, but let go much faster.

FWIW, I might well spent some time/money again for the third time to build

a simple free job listing system if people would be interested. At least, I am

not aware of the "default" spot where all the Ruby/Rails jobs, projects,

available people are listed (if that exists, certainly interested to know).

Maybe, it even makes sense to build that as an open source/community

project, so _we_ (and not the recruiters) can decide how the thing works ...

Revenue could come from "VIP" jobs that get more prominent html

decorations.

I you give me positive feedback, I am on it! If I get no feedback, no prob,

just confirms previous conclusions :-)

In any case, I object somewhat to a massive amount of job spam on

this list (but indeed, I could filter on the [JOB] in the subject line).

Curious for any feedback,

Peter

It would probably just annoy people if they were not told until they'd
entered all their "new duck" requirements that they'd reached their
limit. So I'd also keep a permissions-type check in the controller
too. As Colin says the code to check for this is in the model, so can
be re-used by the permissions check and the validation.

class DucksController < AR:Base
before_filter :check_duck_limit, :only => [:new, :create]

def new
@duck = Duck.new
end

private
def check_duck_limit
flash[notice: "You have reached your limit. Upgrade your plan."]
if current_user.reached_duck_limit?
end
end

class User < AR:Base
validate :has_duck_availability

def reached_duck_limit?
self.ducks.count >= self.max_number_of_ducks
end

# in case a user can not yet have a plan, it's handy to make sure
it exists, and return a safe value
def max_number_of_ducks
plan ? plan.max_number_of_ducks || 0 : 0
end

private
def has_duck_availability
errors.add(:duck_count, "has been reached") if reached_duck_limit?
end
end

PS you don't need to assign "current_user" to an instance variable -
just use current_user ;-)

PPS Your current code alerts when the limit is exceeded, rather than reached

I think you're on the right track having a *warning* show up in
ducks_controller#new. If, as Colin suggested, you have the *model*
check for excessive ducks as well, #create shouldn't need any
alterations from the standard scaffold-generated style. (At least,
not for this reason.) It will make the save fail, detected by
#create, which will just render #new again, with the errors carried by
@duck.

Probably your view is not checking for errors on the object. You need
code in it something like:

<% if @widget.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@widget.errors.count, "error") %> prohibited
this widget from being saved:</h2>
<ul>
<% @widget.errors.full_messages.each do |msg| %>
<li class="error"><%= msg %></li>

</ul>
</div>

Check your view (or layout) for such code, and if not there, stick
this in, substituting your model name for widget.

Category/Subcategory -> Resellercategory -> Product

If I filter the products for "male" I only want to display (non-empty) Categories/Subcategories that have male products.

To answer your question, there is no pagination on the Categories and Subcategories that I'm fetching here with this query. The query only returns the appropriate Categories/Subcategories. So if filtered by "male" it returns 3 Categories and 12 Subcategories (In my dev environment).

OK, I understand (small amount of categories, much more products).

If you find no other way, then the caching the "has_male_products" etc

in the Category/Subcategory may be the best remaining way.

I was also thinking, maybe it is acceptable that the set of Categories

with "male_products" etc. is only update every hour or so. That would

avoid the complexity of real-time update of that cache column. On the

other hand, an after_save on products is not _that_ difficult.

Just as a test, does your performance improve significantly if you add

a "has_male_products" column on categories and filter on that?

If I filter the products for "male" I only want to display (non-empty) Categories/Subcategories that have male products.

To answer your question, there is no pagination on the Categories and Subcategories that I'm fetching here with this query. The query only returns the appropriate Categories/Subcategories. So if filtered by "male" it returns 3 Categories and 12 Subcategories (In my dev environment).

I am using pagination for the actual products though, but that is a separate query.

It's nowhere near the same scale as cities in the US and Europe, but Wellington, New Zealand definitely has a lot of demand for Rails developers right now.

I also know of recent jobs openings in Christchurch (if you can't take the shake), Nelson, and Auckland.

I would suspect the market in Australia is hot. Sydney, Melbourne, and Brisbane probably best bets, though supposedly there is a big shortage of IT workers (haven't heard Rails specifically) out west to support the mining industry.

Australian pay is better than NZ pay due to exchange rates.

Personally, I'm looking for at least one junior level developer to work with me on projects as a freelancer. Remote from anywhere is fine as long as you have excellent English language communication skills. If you can't write and speak in English well, it's a non-starter. I expect some sort of code on github to look at too. Contact me at wm -at- waltermcginnis dot com.

Hi

I tested to remove the .order(...) part and indeed, the query time goes down to ~100ms. However, it doesn't help to add indices, at least not as I did :)

add_index :categories, :name

add_index :subcategories, :name

Did some more testing and if I keep the .order... but don't join the products table I get a query that runs at about ~55ms. So the bottleneck seems to be the products table.

The query that I'm running looks like this:

Category.eager_load(:subcategories)
.joins("INNER JOIN products AS p ON resellercategories.id = p.resellercategory_id")

.order("categories.name ASC, subcategories.name ASC")

(Skipping the gender here...)

What I have is Categories and Subcategories. They are related to each other through a Resellercategories table. Products are related to Resellercategories.

So, the reason that I want to join the products as well is because I only want to show categories and subcategories that actually have some products (there are some empty categories/subcategories still).

So the above query is what we came up with in another thread here in the group.

- Maybe there is a better way to check if a category/subcategory has products without joining the entire products table?

It is possible to add a :counter_cache , but then you need to make sure you
use the proper methods for each product that you add or remove from the
association.

Alternative to the default counter cache (from Rails), you could build your own
logic as in:

* has_male_products
* ...

changing you query to ...

Category.eager_load(:subcategories).
where(:has_male_products => true).
order(...)

Then you would need to set the cache on the appropriate categories in
an after_save on the product you are creating/updating/deactivating/(deleting ?).

Both ideas would probably be faster for querying, but certainly more
complex for making sure that cache is always correct.

Sorry to reply to my own post.

TL;DR Is there pagination? Then a smaller set may return much faster.

I was thinking over my reply and may have forgotten a fundamental

aspect ... If you say 2200 categories, 8000 products.

How many entries does you query return ?

(replace .add with .count at the end).

How many do you need ?

What happens when you add .limit(20) to your query ?

By which "primary object" do you want to sort and paginate ?

(I will assume 'Product' in the discussion below).

With the includes that are currently implemented, you may

have to redo the whole query into 2 qeuries ...

1) for fetching the "primary objects"

(e.g. exactly 20 Products, no additional "has_many" data, because

that would increase the number of returned rows for 1 product and

make proper pagination in the database impossible; including

"belongs_to" here is no problem)

2) a second query for fetching eventual "has_many" data

on those 20 "primary products" (is that "Reification" ?)

If the performance problem could be solved by taking the

pagination into account, that would be a _much_ better

solution that building cache columns in this early phase

of your project.

[Rails] How to add multiple user create on single form using ActiveAdmin

2012-01-26T11:00:00.002-08:00

HI All,

I am currently creating an Admin utility for courier management service, where I need to include a form to submit two users(same model) on same form, I don't know to implement exactly but duplicated the user form twice which is displaying the form twice on the browser but unable to save the both the users, listed below my Admin customer register file and attached the screen shot for your reference .

Also want to know, how to add additional business logics to admin, for example adding print functionality for the single user on 'view' page.

ActiveAdmin.register Customer do
form do |f|
    #User one
    f.inputs "Sender Details" do
      f.input :name
       f.input :email
       f.input :street
       f.input :city
       f.input :state
       f.input :pin
       f.input :customer_type,:as => :select, :collection => [["Package Sender", "Package Sender"], ["Package Receiver","Package Receiver"]]
    end

    #User two
   f.inputs "Receiver Details" do
      f.input :name
       f.input :email
       f.input :street
       f.input :city
       f.input :state
       f.input :pin
       f.input :customer_type,:as => :select, :collection => [["Package Sender", "Package Sender"], ["Package Receiver","Package Receiver"]]
    end

    f.inputs do
    f.has_many :packages do |p|
       p.input :weight
       p.input :amount
       p.input :received_date
       p.input :amount
   end
    end
    f.buttons
end
end

I don't know about better, it was expedient and didn't create a third view file.

[Rails] Can't access polymorphic associated model's attributes

2012-01-26T10:38:00.000-08:00

Hi!!

I have a few models that use a Photo polymorphic model. It's all good
and fine for saving or accessing the photos' attributes via console or
inspect or logger, but if I try to call them directly in the view
with, for example, @banner.photo.file, it returns a undefined method
'file' etc for nil:Nil

Photos are being uploaded via paperclip and all models are set with
has_one :photo, :as => :imageable and
accepts_nested_attributes_for :photo, :allow_destroy => true. And the
Photo model is set as belongs_to :imageable, :polymorphic => true and
has_attached_file :file.

These are the columns for the Photo model:

id:integer
file:string
imageable_id:integer
imageable_type:string
file_file_name:string
file_content_type:string
file_file_size:integer
(besides created_at etc)

In my view:

<% @banners.each do |b| %>
<%= b.photo.inspect %><br />
<% end %>
You can see the inspect at http://bdyvu2.hospedagemweb.net/

Many thanks in advance!! Going out of my mind here!! (been at it for
days!)
