Re: [Rails] Recording remote_ip that created a record in a nested form

Ruby on Rails Thursday, March 31, 2011

When a user creates a new record, it should be through a request with the nested form which is then handled by a controller somewhere in your application where you will have access to the client's IP. You would then need to store that IP address as part of your model for later retrieval / display. Right? Or am I not understanding your question?

[Rails] integrate facebook

Ruby on Rails

@kiran:

for integrating facebook,

i tried facebooker which is outdated, not suitable if you are using rails 3.

i'm using fbgraph right now, you can download a sample app from --> https://github.com/nsanta/fbgraph_example

and see how it works.

you might also wanna look at another gem -> koala (i haven't tried it but it works with rails 3 afaik)

hope that helps :)

Try it in your SQL console of choice:

UPDATE my_table SET field1 = 'new value' WHERE id = <non-existant-id-value>

You'll get a message "no records were updated" - that's a successful
execution as far as SQL is concerned.

Are you sure you're not getting "undefined local variable save_seq"?
Did you cut/paste the code here, or did you re-type it (so is it
*exactly* what's in your controller, or could there be small
differences?)

It could be worth you setting save_seq:
high = Users.find(:order => 'sequence_at DESC', :limit => 1)
save_seq = high.sequence
unless high.sequence.nil? || high.sequence == 0
...etc

I am posting a related question in the same thread.
It is more of a philosophical question.
Can anybody please give me some philosophical explanation why the
following behavior of ActiveRecord is considered ok (or should i submit
a bug report/feature request?):

In console:
> p = Person.create(:name=>'Bill')
> p.destroy
> p.name # => "Bill"
> p.save # => true
Nothing is saved in the database, but what disturbs me more is that
"save" returned true in such case.

In this first example you are inializing an object instance of Person by calling the "create" method. The "create" method of class Person does a "create" to the database where as the method "new" does not. The "destroy" method you called sends a destroy to the database for the record based on that id but does not destroy the obect instance. This is because object is not a pointer to the database record, it's an instance of the class Person. This is why you can still retrieve the name from your object instance later by calling the method "name". The "save" method should be doing the action of create or update in the database (depending on if the "new" or "create" methods were called to inialize the object instance). It returning "true" is strange since the record in the database is neither being created or updated. That may indeed be a bug.

A more elaborate version:
> p = Person.create(:name=>'Bill')
> p.id # => 1
> pp = Person.find(1)
> pp.destroyed
> p.persisted? => true
> p.destroyed? => false
> p.save # => true
but the database is empty.
Again, what bothers me the most is the "true" returned by "save".

In this example you are inializing two seperate object instances of the class Person. One by calling the method "create" and the second by finding the first record in the database. Again, object instances are not pointers to the database record. The objects "p" and "pp" are totally seperate. Like above, activating the "destroy" method sends a destroy to the database based on the id in the object but does not destroy the calling object or any other object that happens to have the same id value. The "save" method returning true is strange since the record with the id value of 1 can't be created again or updated.

Someone else might know more as to why "save" returns true in this case. If not, then it is most likely a bug.

[Rails] Route with optional segments

Ruby on Rails

In Rails 2.3.5, is this the proper way to do this?

map.calls "calls/:group/:view/:subselect", :controller => 'calls',
:action => 'index'
map.calls "calls/:group/:view", :controller => 'calls',
:action => 'index'
map.calls "calls/:group", :controller => 'calls',
:action => 'index'
map.calls "calls", :controller => 'calls',
:action => 'index'

I want to accept

/calls
/calls/abc
/calls/abc/def
/calls/abc/def/ghi

where "group" would be assigned "abc" in cases 2-4, "view" would be
assigned "def" in cases 3 and 4, and subselect would be assigned "ghi"
in case 4.

I kept trying to do something like:

/calls(/%group(/%view(/%subselect)?)?)?

but never got it to work.

Thank you,

Well, really, the elegant way is to have the ID in the URL, and GET
it. It's not great practice to use POSTs when a GET would do, simply
for comestic reasons.

Is there a particular business reason you can't have the ID of the
property in the URL? If it's simply that the URL doesn't look pretty
with a querystring attached, you could make 'leases' a nested
resources, so the URLs could look like this:

/properties/1/leases/new

If it's genuinely unacceptable to have the property ID in the URL,
then you will have to send it as form data in a POST, yes. If you want
to avoid JavaScript, but still have the element look like a link
rather than a form submit button, it's possible to style buttons as
links:

http://natbat.net/2009/Jun/10/styling-buttons-as-links/

but this is starting to look like a hacky solution to a non-problem.
Can you elaborate more on what you're trying to achieve?

[Rails] Re: Ruby on Rails for Tablet Computers (Android OS)

I've not heard of Mirah. Certainly like the idea though.

I have decided to drop the whole rails approach.

I had designed a rails app to act as a full point of sale

It would be accessed over tablet pc browsers.

I have done some testing today accessing the web app via safari on the
ipad and the latency was terrible.
So much so, that it renders the product un-usable.

I am going to have to go full android I think.
Maybe have some backend to dump the data using some rest API.

Any advice for taking such a route?

[Rails] Google Charts API use

Ruby on Rails

Hello, I'm testing Google Charts API plugin for rails and have a few
questions about it's use (I searched for a developper documentation
for about an hour without founding anything really interesting):

Here is my test code:
# Testing google charts api
chart = GoogleChart.new
chart.type = :bar_vertical_stacked
chart.height = 400
chart.width = 600
chart.data = [@totalAmount, @totalPercent]
chart.colors = '346090'
chart.labels = ["total", "percent"]
@small_sales_chart_url = chart.to_url

And in the view:
<%= image_tag @small_sales_chart_url %>

The generated graph url is:
http://chart.apis.google.com/chart?chs=600x400&cht=bvs&chco=346090&chl=total|percent&chd=t:300.0,100.0

This is great, but I would like to know how to:
- Set the space between each bar
- Define the y axis labels
- Create a bar with values that can be negative
- Write the value of each bar directly on the graph
....and so many more.

If anyone knows where I could find a complete developper guide that
would be great, if not maybe you can help me with those few questions
in the meantime.

Thanks!

Re: [Rails] can i switch to rails 2.3.5 and run a rails 2.3.5 code??

Ruby on Rails

You should look at the gemsets feature of rvm. Then you can use
the .rvmrc file in each project to select a gemset (and a ruby
interpreter). After you've done this, each project will see just its
own gems. You can use bundler to manage the gems locally, too, which
makes it quite painless to deploy to the production environment for
each project and get just the set of gems needed.

Are you talking about the whole database or just the users table? The
way I read your post it looks like you just want to validate users and
keep only one table for all users. If that is the case why not set up
a connection in the application that does not own the users table that
is only used by the User model? That should be enough to give you
access to the user information you might need.

Re: [Rails] link_to with hidden parameters

Ruby on Rails

I know that I could do a javascript function or create a hidden form
but was wondering if there is a more elegant way to solve this, as it
must crop up all of the time.

taking those 2 out , and the uri, how will the server know what you want?

you can map is to the uri so you dont use ?property= not you have to tell the server what you want.

Do you know what the user's timezone is? If so then take the timezone
offset (which is distinct from the DST setting) and calculate the time
accordingly.

[Rails] Re: ActiveRecord: when exactly is a record (model) saved to the database?

Ruby on Rails

I am posting a related question in the same thread.
It is more of a philosophical question.
Can anybody please give me some philosophical explanation why the
following behavior of ActiveRecord is considered ok (or should i submit
a bug report/feature request?):

In console:
> p = Person.create(:name=>'Bill')
> p.destroy
> p.name # => "Bill"
> p.save # => true
Nothing is saved in the database, but what disturbs me more is that
"save" returned true in such case.

A more elaborate version:
> p = Person.create(:name=>'Bill')
> p.id # => 1
> pp = Person.find(1)
> pp.destroyed
> p.persisted? => true
> p.destroyed? => false
> p.save # => true
but the database is empty.
Again, what bothers me the most is the "true" returned by "save".

Rather than storing a timezone string you could just store the offset,
so since I'm in "Central Time US & Canada" I would just use "-0600"
which would avoid DST when we switch to -0500.

[Rails] link_to with hidden parameters

Ruby on Rails

Hi All,

Sorry if this has been asked before, I'm just looking for a pointer on
the 'standard' or accepted way to get around this issue, as oppose to
some 'bodges' that would seem workable.

Dead simple:

I have an index page for model 'properties' which needs a per-property
link to create a new 'lease'. A link_to is fine for jumping to the
'new' page of the 'lease' model, however I want to pass the
property_id for the lease to the controller, without it appearing in
the url (Presuming I will thus have to POST it)

I know that I could do a javascript function or create a hidden form
but was wondering if there is a more elegant way to solve this, as it
must crop up all of the time.

Thanks in advance for any helpers with this

Paul

[Rails] Re: Is there a way to ignore DST?

Ruby on Rails

See if TimeZone.period_for_local works for you. It has a DST=false parameter.

Re: [Rails] Re: Parse selectbox value with javascript

Ruby on Rails

If you have multiple elements on your page that have the literal value
name="algo" then the last one will "win" and only that one value will
be submitted to the server by the browser. If they are actually
name="algo[]", then you will receive an array of values for algo and
you can iterate over them on the server with each(). In Prototype, you
can get all of the values for the current form in one serialized
string like this (inside your Ajax Request):

... parameters: this.up('form').serialize(), ...

Then your controller method can pick out the ones you want
with :params[:algo] or something like that.

As opposed to running the server on the handheld, have you looked at

It's very, very ruby-like.

it is also already fully functional, and is just a simple gem install

[Rails] Affordable developer with good software design skills?

Ruby on Rails

Hi All,

Apologies if this is verging on O/T for the list, but I do see some job ads and I've been trying to contribute substantively to the list for the last couple of months.

I'm in the horrible position of having too much work, but some of it isn't that profitable so I can't go to my regular guys who are $100+/hr. Simple content management systems, etc. All in Rails 3.0.x with Ruby Enterprise 1.8.7 being deployed on Heroku using SendGrid, etc. I need someone to create a good first cut of sites. They need to use rvm, use git and create meaningful commit messages every 15 mins to 2 hours as they complete discrete chunks of work, name their fields and classes intelligently, keep method sizes low (most 6-8 lines, all under 20 or so). They need to know Devise for authentication, Cancan for authorization, Paperclip (with S3) for file uploads on Heroku and be equally comfortable with haml and erb. They also need to naturally write at least some acceptance tests first using cucumber and capybara, and write some rspec tests for any areas of business complexity. I'm not looking for high levels of coverage in rcov, but a decent effort to have some degree of smoke testing of the app which we can upgrade over time. Some of the apps may need a little jQuery loving, but nothing too complex.

I have a specific project now, and then 2-3 a month coming down the line. Anyone who feels they meet the criteria and would like to build a relationship, please drop me a line off-list (peter@pbell.com) with some information about yourself and your rates. To give you an idea, depending on your productivity this is the kind of work that would make sense at maybe $20-25/hr assuming you can knock out sites pretty quickly, so it's either offshore or "beer money" work. Eventually I'd want to just pay hourly so we're both focused on doing things both well and quickly, although I might give some specific well specified stories for a fixed bid to try things out on the first project.

And now back to our regularly scheduled tech conversations - apologies for the interruption.

Best Wishes,
Peter

[Rails] Re: Parse selectbox value with javascript

Ruby on Rails

Thanks for the fast request.

Do you also know how it's possible to read all values of different
selectboxes in different div-tags (but all with the same name "algo")
with prototype: Is there a way to loop over all those div-tags and read
the value of the selectbox in each div-tag?

You have to have JavaScript in your page which will respond to the
'change' event on your selectbox by sending an Ajax request to your
server. At that point, it will be a normal Rails request, and you'll
have the values. Your server will respond with the result. There are
helpers (or used to be in Rails 2) to generate this JavaScript for
you, but it's important to understand that you can't (from Ruby, in
Rails) ask the browser anything. You have to be waiting for it to ask
things of you.

The Prototype-flavored JavaScript to do this would be something like
this:

$('mySelectBoxId').observe('change',function(evt){
new Ajax.Request('your/server/endpoint',{
parameters:{mySelectBox:this.getValue()},
onSuccess:function(transport){
//do something with
transport.responseText
},
onFailure: function(transport){
//sad face
}
});
});

You can probably get similar code injected into your page for you by
one of the Rails helpers, but that's the basic mode by which it will
work.

Re: [Rails] Re: Where do I put code when I share a partial between two controllers

I think this is just basic to how Rails works. The controller responds
to requests with methods. Those methods may be further decomposed into
other methods and variable values, but your statement is true as far
as I understand it.

[Rails] Parse selectbox value with javascript

Ruby on Rails

Hey guys,

i've the following question:
how can i parse the value of a selectbox within a div-tag (with the id
"ma") via AJAX and use the parsed value for reading out some data from
my database. the parsing request should be started by selecting another
selectbox.

My mainquestion is: how can i parse a selectbox (if possible with rjs)
an get the value in ruby (not just in javascript) for further actions
(like reading out some data from database)?

thank you for your response!

Ruby on Rails

Thanks for your response, sorry but my unknows go far away:

I have two entitys:

1- Views or Partial: and I undersant this: render :partial /shred/foo

2- Method/controller (X). now I place this method in
application_controller and the .js.rjs in views/application/X.js.rjs. It
works

But I do that because in "menu" controller and "Maintenance" contoller I
call X, but not as a "redirecto_to" otherwise as a normal call, as if it
was a function, only to initialize variables.

So that, I need to put X method in applicationController, to be seen
from the others controllers (menu and Maintenance).

--> And this is weird, ¿ or not ? the X method is used for two porpuses:
as a response of a browser JS request, and as "function"

And to tho that I put in X:

if request.xhr?
respond_to do |format|
format.js
end
end

thanks again

[Rails] Form method="post/get" and routes

Ruby on Rails

Hello there,
I'm doing a form and I want to send this form with method="post". Head
of form looks so:

<%= form_tag({ :controller => 'admin', :action => 'menu_add' }, {
:method => 'post' }) do %>

And in controller I have this:

def menu_add
menu_new = Menu.new(...)
...
end

And with I am fighting - I'm not using type of route get
'admin/menu_add' - I'm sending a form by method post -- but I am still
getting the route error "Unknown action - The action 'menu_add' could
not be found for AdminController" -- how it is possible, if I'm not
using route 'admin/menu_add' by get, but by post?

And one question yet - exist some effective way, how to work with
routes? If i want to add some new action, I must to add to file
'routes.rb' line as:

get 'admin/menu_add'
post 'admin/menu_add'

It's a bit boring to add every new action so manually... is some better
way, how to do?

Thanks a lot, Manny.

You can put ERb into your database.yml, and Rails will evaluate it before loading the YAML.

Not sure if this is the best solution for you, though. I think that depends on exactly how you intend your customer to edit these settings. But it's an option.

What's the error message you get? "divide by zero"? or "1 parameter for 2"?

divide_numbers(actual.to_f, expected), :

In this event, you *are* passing two parameters to the method, one as
a float (which, if it started as an empty string, will be turned to
0.0) and the expected value, which may be nil (or an empty string), or
a number. Is there anywhere you are ensuring it's a float like you do
the "actual" value?
Maybe try:
divide_numbers(actual.to_f, expected.to_f)
...to get more consistent results from a range of input values.

BTW, have a play in the console too, to see what different
combinations give you:

>> 2/0
ZeroDivisionError: divided by 0
>> 2/""
TypeError: String can't be coerced into Fixnum
>> 2/nil
TypeError: nil can't be coerced into Fixnum
>> 2/0.0
=> Infinity
>>

...try that with your divide_numbers method...

yes, the full stack would be required.
I am using rails3 btw.

are you looking for the full rails stack? Or would a ruby-based MVC stack work for you? Look at http://rhomobile.com/.
I have used them in the past, and they do what you want, but its not a full rails stack, more like a ruby-mvc subset.

thanks for your reply.

I think you are right in what you say. It would be too much of a
memory hog to do such a thing.

I will have to have a dedicated server for the hosting of the RoR app.

I am building a point of sale system where the interface is html on a
tablet pc, so I was digging into my options.

May be best to just access a small linux server over wifi.
