I don't see how db configuration UI might help me on this.

maybe as example, at best

[Rails] Why can't I access attributes in rails model?

2012-01-30T12:09:00.000-08:00

Hi, I'd like to know why I can't, or how can I, access attributes like that:

class User < ActiveRecord::Base

def name

@first_name + @last_name

end

first_name and last_name are user attributes in the database.

Thanks in advance.

[Rails] Exploding active record results

2012-01-30T11:46:00.001-08:00

Hey guys,

I've got a table that stores events with a recurrence pattern. I found a stored procedure that will generate occurrence dates for an event between a start and end date.

What I'm wondering is how to go about exploding a result set. For instance, if I have one row for an event, but there are 5 dates it falls on that are calculated on demand (not stored), how can I query with AREL to return 5 events, with the same data for each field plus a new field "date" that will contain the date of the occurrence?

For instance, if the original table contained fields a, b, and c - the result of this method/query would be 5 objects with fields a, b, and c - but also one that stores the date.

Thanks in advance,

Jayme

It has nothing to to do with content on that database itself.

I'll be darned ... that's it exactly. I took the exact code that failed
on Rails 3.0.10 and updated my Gemfile to use 3.1.0, and it worked fine.
Great, now I have to go see whether my project which is heavily
dependent on legacy stuff can support having their Rails version
upgraded. :-/

(On a related note, Vagrant is wonderful for this sort of thing! :))

Using HMT (has_many :through) rather than HABTM will make your whole
problem go away, with no need for worrying about threading, object
context, etc. (At least, any more than usual!)

Try using an association table, to represent a given member's
membership (hey, sounds like a good class name there!) in a group.
That's where you can put info like whether they're current on their
dues *for that group*, when they joined *that group*, etc. etc. etc.

[Rails] gdata gem on rails 3 ruby 1.9

2012-01-30T07:44:00.001-08:00

Hi:

Im trying to use gdata 1.1.2 on a rails3 ruby1.9 project
I added gem 'gdata' to Gemfile
but keep getting the error: uninitialized constant GData::

I installed the gem with no problem
Does anybody knows how to setup rails3 with gdata?

I'll really appreciate any advice

[Rails] Separation of concerns and more...

2012-01-30T06:56:00.001-08:00

Say you have an app not dissimilar to StackOverflow where users vote on posts. Say an Up Vote causes the voter to receive one reputation point. You might see something like this in the vote_up model:

class UpVote < ActiveRecord::Base
belongs_to :user
after_create :increase_user_reputation

private

def increase_user_reputation
    user = self.user
    user.reputation == user.reputation + 1
end
end

There is one issue with this code: The value 1 is hard coded. Where does such a value belong? Another issue is that some UpVote should have no knowledge of user.reputation. We solve this by changing the callback:

def increase_user_reputation
    self.user.modify_reputation(1)
end

Then we add an instance method to User:

def modify_reputation(reputation)
    self.reputation = self.reputation + reputation
    self.save!
end

Questions...

1. Who's responsible for calling save! ? The increase_user_reputation inside the UpVote model or the modify_reputation method inside the user model?
2. The +1 one to reputation doesn't seem like a good idea to hard code. Where does Rails keep such configuration settings?
3. Does the code look reasonable? Are there any shortcuts?

This is on version 3.0.10. Since it should work and seems to work for
you I thought maybe the altered table names could be causing a problem,
but I set up a new app with just these three relationships and the
traditional table naming conventions and it's still causing a problem.

I'll see if I can whip up a virtual machine to try an updated version of
Rails. Thanks for the idea.

Er… That's not what SSO means.

@OP: OmniAuth by Intridea is quite famous, and a lot of people use it.

Here's a guide I found helpful for SSO using omniauth + devise

change in the controller

@attched_image = AttachedImage.new(params)

@attched_image = AttachedImage.new(params[:attached_image])

if above not working because of form_tag usage

then you have to use custom new like

@attched_image = AttachedImage.new(:image=>params[:image])

this should work.

You should not add 'self.save' to the method, as you are calling these functions in 'before_save'. It means these functions will be invoked before saving any object of that model. Calling 'self.save' inside it will result in an infinite loop.

Re: [Rails] data is storing in database when i had created but it is destroyed after the sign out

2012-01-29T22:31:00.000-08:00

I believe one of the validations is failing in the case where you update the user profile. Try using something with bang operator(like 'save!') in the code where you update the user profile (in the controller) to identify which validation is failing. ('!' will raise an exception if any validation is failed).

2012-01-29T20:54:00.001-08:00

What version of rails do you use? This setup works fine for me on
3.1.3 and 3.2.1

[Rails] Reaching into a has_and_belongs_to_many - will :through work?

2012-01-29T19:52:00.000-08:00

Hi. I'm hoping somebody can tell me that I've just gotten my syntax
wrong and I can in fact do what I want to do.

I've got a Group, and a Group has_many Campaigns.

Campaign has_and_belongs_to_many Users (and, naturally, vice versa).

So I've got a groups table, a campaigns table (that has a group_id), a
campaigns_users join table (with campaign_id and user_id), and a users
table (who basically is left not belonging to anyone).

My question is this -- starting from Group I want to reach through that
HABTM and point directly at the Users who belong to this Group. I've
successfully done it by writing my own finder_sql, or by just cheating
and collapsing all the camaign.users together. But I'm working on a
user interface for this and I'd like my list of users to behave just
like any other activerecord operation so that I can page through them,
sort arbitrarily on columns and so on exactly as if I'd originally just
had "Group has many Users".

I was hoping that this would work:

class Group
has_many :campaigns
has_many :users, :through=>:campaigns

class Campaign
has_and_belongs_to_many :users

But it doesn't, all I ever get is
ActiveRecord::HasManyThroughSourceAssociationMacroError: Invalid source
reflection macro :has_and_belongs_to_many for has_many :users, :through
=> :campaigns. Use :source to specify the source reflection.

However I don't understand what it wants in the :source option. It's
not like I mucked around with any class_names. (Well, technically this
is inheriting an old database so the actual table names are being
overridden, but I'm hoping that's not it! it's not as if I'm getting
bad SQL generated because an assumed table name does not exist).

Thanks!

gem environment output:

I can also type which bundle:
/home/giglinke/.rvm/bin/bundle

But anything else (bundle -v, bundle install, etc.) gives me the error

gem install bundle works exactly as original poster listed.

...is this an rvm thing?

Any ideas?

I don't understand. index.html.erb is for showing the list of
something. What's "NewScript" got to do with it?

You may be on *almost* the right track though. Assuming you get to
views/scripts/new.html.erb by clicking on something associated with a
video, you can set the new script object's video_id in the controller,
and add a hidden field to hold it (for submission to create).

> @script.video = Video.where(:video_id)

That where-clause isn't going to work. It's just saying "where
there's a valid video_id". Maybe you mean where :video_id => video.id
(if there is a variable called video), or maybe video_id.

Anyway, more direct would be simply "@script.video_id = video_id". No
searching needed. Assuming of course that you already have the
video_id.

BTW, do you know the definition of "Where Clause"? It's a fat guy who
dresses up in a red suit and gives out presents, when the moon is
full. ;-)

Depends. If you haven't yet run rake db:migrate, you can just edit
the migration, but you need to know what you're doing if it's complex.
If you've already migrated, and you've used any new columns or tables
you've added, then you must create another migration. If you've
migrated but not used the new columns or tables, and it's a migration
that CAN be rolled back (not all can), you *can* roll it back (rake
db:rollback), fix it, and re-migrate... but you must be *very* certain
that your rollback won't lose you any data.

[Rails] Looking for Ruby on Rails Developers - Broomfield, CO

2012-01-29T14:26:00.000-08:00

Our client brings 30 years of experience in the energy business, more
than 15 patents, and over five million devices deployed throughout
North America. They have earned widespread recognition and the trust
of utilities, regulators, and consumers as a pivotal energy resource.
Our client is the undisputed leader in Residential Demand Response and
is working hard this year to take that title in the Commercial and
Industrial space. They have over 3500 megawatts of power under
management and have grown their revenues 38% annually over the last 5
years. They take the risk out of implementing complex energy
management programs by leveraging their deep understanding of customer
challenges and requirements.

Our client brings unparalleled industry knowledge and experience to
offer the most reliable, easy-to-use, and cost-effective intelligent
energy management solutions. They deliver the insight and control that
enable energy providers and consumers to optimize their power usage
and meet peak demand through the industry's only proven, comprehensive
set of technology, services, and information management solutions.

Our client builds software that allows utilities to curtail load on
the electrical grid so that they can meet demand without building more
power plants. So this puts them squarely in the Smart Grid, Green
Energy space. If the idea of writing software that controls devices in
the real world instead of simply updating another social network page
excites you, then this may be the position for you.

• Tired of working for social media startups that have no revenue
plan?

• Want to work for a stable company with a proven business model,
without losing the feel of a small, agile team?

• Want to write software that contributes to solving our energy
problems?

• Do you want to help make the smart grid actually smart?

Our valued client is looking for several Rails Developers. The Rails
Developers should be comfortable working across all tiers of a web
app, heavy Javascript (jQuery based) on the front all the way to MySQL
in the database layer. Ruby is the primary language, but there is also
a reasonable amount of iOS work and the beginnings of Erlang. Neither
of those skills are required for these positions, but rather a
differentiator. Come join one of the most ambitious and challenging
Rails projects in existence.

Responsibilities:

• Work across all tiers of a web app, heavy Javascript (iQuery based)
• Work with Ruby language
• iOS work, and the beginnings of an Erlang effort

Requirements:

• Bachelor's degree preferred or equivalent experience
• Rails experience
• Experience developing across all tiers of a web app
• Experience with git
• Somewhat obsessed with TDD or BDD
• Predisposed to pair programming
• Spurred to action when the build breaks
• Self-motivated to refactor and make improvements

[Rails] Custom form builder

2012-01-29T11:11:00.000-08:00

Hi,

I am trying to create a custom form builder but got the following error: wrong argument type Class (expected Module)

To create a form builder I have to subclass ActionView::Helpers::FormBuilder. So, I guess, it must be a class and not a module or maybe a class wrapped inside a module....

Here is the idea:

The helper (/app/helpers/custom_form_helper.rb):

class CustomFormHelper < ActionView::Helpers::FormBuilder

    def datalist_for(method, choices, options = {})
     ...     # I'd like to render a partial here with :locals => {:list => choices, :name => @object_name + "[_#{method}]"}
    end
end

The partial (app/view/shared):

<input type="text" name=<%= name %> list="list">
<datalist id="list">
    <% choices.each do |elem| %>
        <option value=<%= elem %> >
    <% end %>
</datalist>

The view:

<%= form_for(:moove, :builder => "CustomFormHelper" :url => {:action => 'create'}) do |f| %>
    <table>
        <tr>
            <td><%= f.datalist_for(:sport, @sports)%></td>
        </tr>
    </table>
<% end %>

Thank you in advance for your help,

Maybe this option can help you:

# Don't fallback to assets pipeline if a precompiled asset is missed

config.assets.compile = false

from http://guides.rubyonrails.org/asset_pipeline.html .

It's off (false) by default, but if you wanted you could turn it on.

In that case, you probably need to make this group

in your Gemfile

# Gems used only for assets and not required

# in production environments by default.

group :assets do

gem 'sass-rails'

gem 'coffee-rails'

gem 'uglifier'

gem 'bootstrap-sass'

end

also available in production (which would mean to put it

outside of the :assets group).

[Rails] Starting Full Server Stack During Integration Tests

Hello all,

I want to use Selenium (not capybara, I like the Selenium syntax
better) for some of my integration tests, and Selenium needs a full-
stack HTTP server to test against. How can I start the full-stack
server during integration tests so I have a url to give to Selenium?

Also, eventually I will want to run the same tests against a staging
server. What's the best way to change a single parameter (the url) but
keep everything else about the tests constant?

Hi,

I am Karthik and I am developing an HTML5 application for creating mockups and a css previewer (something like webputty from FogCreek). I am looking for a few good ruby on rails developers. I am in search for the following skills :

1. Rails 3.1/3.2 with devise, omniauth, experience
2. jQuery + HTML5
3. Frontend skills are a good to have but not necessary
4. Git
5. Heroku deployment experience will be a plus.

I am willing to pay a monthly salary of upto Rs. 30,000 per month (if you are really good, you can always talk me into paying more). But more importantly, please apply only if you are :

1. Willing to work in a startup
2. A code geek and loves writing beautiful and powerful code
3. A self driven, responsible coder who likes to be trusted and in turn gets things done for the company.
4. More importantly, a StarWars fan.

I would be glad if you can send me a github profile and other pieces of code that you have written previously. If you feel one of your friends could fit in, do share this with them.

Thanks
Karthik

= :strict and I'm hoping some one can offer me some guidance to
improve my tests.

The problem:
Say you have a test that looks like this:

it "allows you to create an object" do
obj = FactoryGirl.build(:object) # #<Object id: nil, name: "Foo
Bar", created_at: nil, updated_at: nil>
post :create, :object => obj.attributes
response.should be_redirect
# yadda yadda yadda
end

The problem I'm running up against is that because
FactoryGirl.build(:object) returns a built out object that includes
protected attributes such as id, created_at and updated_at in the hash
(this is a simplified example, I have other things in the model not
listed here that are also whitelisted via attr_accessible), when I
post that hash, I receive the following error:

ActiveModel::MassAssignmentSecurity::Error:
Can't mass-assign protected attributes: id, created_at,
updated_at

The above is a simplified example. The model looks a bit more like
this:

class Foo < ActiveRecord::Base
belongs_to :bar
# a bunch of other belongs_to's here
attr_accessible :name, :bar_id, #other belongs_to ids
end

Factory.define :foo do
name Faker::Name.name
association :bar, :factory => :bar
# all the other associations
end

I took a look through factory_girl's docs and found the following
methods for building out models:

attributes_for: doesn't go far enough because I have relations defined
on my factory that need to be built and saved so their IDs can be
assigned to the object upon its instantiation (or in the hash)

build_stubbed: gives me random values for various fields that aren't
valid. Instead of building out the associations and saving them then
assigning valid IDs, it just makes random shit up. That doesn't quite
work.

create: obviously not the right choice when you're testing a post
action on a RESTful cotroller

build: what I'm using now, and then just passing the attributes hash
of the object. Does everything I need, except it includes attributes
that are protected, thus causing the controller to flip out.

Now, I can think of two (three actually) ways around this problem:

1) Go through my really big test base and manually remove any
attribute that's not accessible from the hash before doing a post. Not
at all maintainable and not really a realistic option, but would allow
the tests to pass.

2) Add a before_filter that sanitizes the parameters hash on create
and update actions to strip out any protected attributes by looking at
the model and seeing what its accessible attributes are. This seems
like unnecessary code bloat, though, and kind of a clunky solution to
the problem.

3) [What I really want] I need a way to get FactoryGirl to build out a
hash of attributes when it's first called to NOT include attributes
that are protected or aren't accessible, but WOULD include real object
IDs for all the defined associations. That would allow me to just call
post :create, :object => FactoryGirl.some_method(:object) and be done
with it.

Could anyone offer any insight here as to how I might go about making
this work better? Obviously I could delete the setting from test.rb
but that kind of defeats the purposes, and I like having extra strict
security measures (especially in this particular application).

In the controllers tests that are auto-generated by rspec-rails, there

is e.g. this kind of code:

describe PeopleController do

# This should return the minimal set of attributes required to create a valid

# Contact. As you add validations to Contact, be sure to

# update the return value of this method accordingly.

def valid_attributes

{}

end

...

describe "POST create" do

describe "with valid params" do

it "creates a new Person" do

expect {

post :create, :person => valid_attributes

}.to change(Person, :count).by(1)

end

In that code, I replace it by default with something like this:

def valid_attributes

FactoryGirl.build(:full_person).attributes.delete_if{|k,v| v.nil?}

end

Stripping the non nil attributes from the hash solves the issue.

As you show above, :id, :created_at, :update_at are (correctly) nil

after a build, so this delete_if removes them from the attributes hash.

* I get no warnings on the :id

* I get no violations of nil created_at /updated upon update

So, to centralize this pattern, this hack with a "build_attributes"

seems to work:

../config/initializers$ cat generators.rb

ContactApp::Application.config.generators do |g|

g.helper false

g.test_framework :rspec, :fixture => true, :views => false

g.fixture_replacement :factory_girl, :dir => "spec/factories"

end

module FactoryGirl

# this is a hack

def self.build_attributes(*args)

self.build(*args).attributes.delete_if{|k,v| v.nil?}

end

And now I can do:

def valid_attributes

FactoryGirl.build_attributes(:full_person)

end

HTH,

[Rails] has_many association and parent_id

2012-01-29T02:45:00.000-08:00

Rails 3.1.3

Hi everyone again.

I'm trying to develop a database and tables which have the association
as follows.

Video 1 ----- 0..n Script

So, in 'script.rb'

class Script < ActiveRecord::Base
belongs_to :video
...
end

and in 'video.rb'

class Video < ActiveRecord::Base
has_many :scripts
end

Furthermore, in order to refer to the parent (in this case, 'Video'), I
need to set video_id:integer for Script. Am I correct ?

in the migration file,

#--------
class CreateScripts < ActiveRecord::Migration
def change

create_table :scripts do |t|
t.references :video
t.string :text
...
end
add_index :scripts, :video_id
end
end
#---------

My question is: how can I actually associate a new 'script' entry with
its parent, 'video', in making a new 'Script' entry ?

For example, in 'index.html.erb' for NewScript page, I tried to put

and in script_controller.rb

@script.video = Video.where(:video_id)

But certainly does not seem to work at all.
Could anyone show me how to set up 'html.erb' and 'controller.rb' to
associate a new 'Script' entry with its parent specifically ?

Thanks in advance.

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

2012-01-29T00:01:00.000-08:00

[SOLVED]

don't know if it's the best solution, but it worked...
changed the date text_fields to text_field_tag, on output , set the
value in the controller, with I18n and local format
>> @start_shooting_date = I18n.l( @project[:start_shooting_date], :format => "%d/%m/%Y")

then on input , set the attribute value from the form field in the
controller, with I18n and local format
>> @project = Project.new(params[:project]) # on create
>> @project.attributes = params[:project] # on update
>> @project[:start_shooting_date] = I18n.l(params[:start_shooting_date].to_date, :format => "%d/%m/%Y")
>> if @project.save
this way, the dates are correctly saved in the DB with the
standard :db format but input/output in the form is in local format
"dd/mm/yyyy" ( also defined like this in localized DatePicker

This is again a very basic question.

it generated

20120128103756_create_scripts.rb

But I want to change this model, so instead of redoing it like "rails
destroy .... -> rails generate scaffold...", all I need to do is to edit
the migration file above?
Or do I need to reproduce ANOTHER migration file like above and add

t.remove :text

???

I am a little confused because the migration file above has the
time-stamp, which indicates the time of execution (rake db:migrate).
So, does that mean the file above is useless unless I want to rollback?

[Rails] after_save in plugin

2012-01-28T15:04:00.000-08:00

Dear list,
I am trying to override an after_save callback declared in main app
using plugin.
The main model class is:

class WorkHours < ActiveRecord::Base
@after_save_call_back_called=0
after_save :after_save_call_back
def after_save_call_back
logger.debug "after save called"
@after_save_call_back_called=1
end
end

And in my plugin (in the lib directory) :

module WorkHoursPatch
# cattr_accessor
def self.included(base) # :nodoc:
base.logger.debug "inlcuded called"
base.extend(ClassMethods)
base.send(:include, InstanceMethods)
base.after_save.delete_if{
|callback| callback.method == :after_save_call_back
}
base.send(:after_save, :after_save_call_back_patched)
end

module ClassMethods

end

module InstanceMethods
def after_save_call_back_patched
logger.debug "overriden after save called"
@after_save_call_back_called=1
end
# Wraps the association to get the Deliverable subject. Needed for
the
# Query and filtering
# def is_new
# unless self.is_new.nil?
# return self.is_new
# end
# return false;
# end
end
end
#
## Add module to Issue
WorkHours.send(:include, WorkHoursPatch)

The init.rb says
require 'work_hours_patch'

All this should work and running the console I an see the old plugin
being deleted and the new one added.

Please help!
I am spending on this days!

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

OK I'm confused. The segmentation fault indicates it is happening in the ruby 1.9.1 version of the SMTP library (see quoted text.) However, when I go to my project and enter the Rails console, I get this:

irb(main):001:0> RUBY_VERSION

=> "1.9.3"

And when I go the project directory I get this:

story_project # ruby --version

ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]

The full path on the segmentation fault is:

/Users/don/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/net/smtp.rb:583: [BUG] Segmentation fault

What is the deal here? Why is Ruby 1.9.3 running code from 1.9.1? Is this common? Did RVM mess this up some how?

Perplexing!??

Great! Now let's take it to the next level. I think you can make it
a little more "canonical". Instead of:

> <%= link_to('RegisterThisMovie', {:controller => 'video', :action =>
> 'new', :url => y }) %>
>
> 'y' contains the url of the movie after executing the search.

try:

<%= link_to( 'Register This Movie', new_video_path, :url => y ) %>

Also you can try getting used to the newer hash syntax, and do:

<%= link_to( 'Register This Movie', new_video_path, url: y ) %>

I'm not 100% sure off the top of my head that these will work, but it
should be at least close. :*) The built-in url helpers like
new_whatever_path, edit_whatever_path(some_object), etc. will save you
lots of typing and thus errors.

If you can configure Warden to use the md5 passwords, then do that. Then, modify the login process so that upon successful login you save their password (which you have at the moment in plain text) as a bcrypt-ed string. On next login, verify against bcrypt.

For more info, take a look at authlogic's "migrate from restful authentication" to see how it handles it...

[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:

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

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.

When you say documentation you mean the Rails Guide?

I'll second what Colin said. I'll also emphasize the need to "hold your horses". There's nothing more frustrating than having to wade through a ton of stuff before you start building something. But it's absolutely worth it, and it will save you a ton of time in the long run.

If I had spent 10% of my time reading documentation, I would have saved the other 90% that I wasted editing lines of code, scanning hurriedly over tutorials, asking a ton of questions, etc... it really is true. It's frustrating at first, but it pays off and saves you a ton of time in the long term.
