similar to: find_by_id vs. find in postback action

I was trying to use postbacks, but its not working. def edit @xxxx= xxxx.find_by_id(params[:id]) || xxxx.new if request.post? @xxxx.attributes = params[:xxxx] redirect_to :list and return if @xxxx.save end end I get the following error: SystemStackError in xxxxxController#edit stack level too deep. The code of list is same as the code generated by the scaffold

Tried to submit a ticket in Trac, but it reported an error... Doing a Model.find_by_id(nil) after creating an object of type Model returns that object -- and the next time, returns nil. It should always return nil. For example, Step 1. Create an object: >> Foo.create(:name => "bar") => #<Foo:0x2aaaac3ade20 @new_record=false,

I have a model named User. When running this application from the console I can call User.find_by_id(nil) and it returns nil. When running this application during testing or through WEBrick or Mongrel calling User.find_by_id(nil) returns the newest record in the database. But it only does this the first time you call it with nil. The second time you call User.find_by_id(nil) it returns nil.

I read these: http://www.ruby-forum.com/topic/185297#new http://www.freezzo.com/2008/05/14/override-default-find-conditions-for-model/ it works, it override the .find perfectly, however it does not cover .find_by_id or other .find_by_XXX Is there anyway to override all the find function of a modal? I want to set the default "select" for User modal, only return name and id, but not the

Hi all, I would first like to introduce myself to the Ruby on Rails (RoR) community and to say that I hope to begin to build some relationships with other RoR developers. I''m a long time Java programmer (5+ years). Java was my first experience with Object Oriented Programming (OOP). Before Java I developed using many other languages including C, Pascal, Fortran, BASIC, Visual Basic,

This has the look of a "just don''t quite get it yet" problem. I am using the ActiveRecord.find_by_id method to identify the parent object (Quiz) to tie to the child object (Question) at create time. Here is the stdout log: 127.0.0.1 - - [31/Mar/2006:22:43:22 CST] "GET /question/new? parent_quiz=ff2d7022-be0a-11da-9f01-00400506faf5 HTTP/1.1" 200 806

Hello, I hope somebody can explain to me what''s going on here because I''m baffled! In a controller''s action I want to create a new order for a customer. Because I post back to the same action (not RESTful I know, but that''s for another day) I use code like this: def edit @order = Order.find_by_id(params[:id]) || Order.new ... end I

Hi, The following controller method taking me into infinite loop. Once the update action completes I want to reload the ''index'' page. May I know why it is going into infinite loop? def update Device.find_by_id( params[:device_id] ).driver = ( params[:driver_id] == 0 ) ? nil : Driver.find_by_id( params[:driver_id] ) redirect_to :action => :index, :tab =>

Hi all - I have written an XML-RPC app using action-web-service. Mostly works well. Except I just noticed that my :datetime types are coming back as :date types. That is, when in the console I query the record via Foo.find_by_id(123) I get back actual datetimes. If I then do it via XML-RPC, fetching that same record I get back dates (ie. hour/minute/second are set to 00:00:00) Any ideas?

I want to isolate and spec methods that are shared by controllers, and live in application.rb. Whereas I usually also provide examples in individual controllers that use these methods, not necessarily all the edge cases and I''d like to isolate the examples. This is the approach I''m taking (thanks to bryanl for suggestions and http://pastie.caboo.se/123626). WDYT? This

How do I validate that a model object''s attribute is a valid foreign key? The problem is, I can''t check if the attribute is a valid foreign key if the attribute doesn''t even exist. For example, every employee must be in a department. In the following code, if an employee''s department_id is not present then Department.find_by_id(department_id) might cause

Hi, i''m going to implement a syndication-service, which will get lists in xml with some meta-data an enclosed video files, which will get encoded at the end. The syndication run will be startet every five minutes of a full hour. So i thought to build 4 Worker.

Hi There! I''d like some feedback before I try to implement some funky rails routes based on an acts_as_tree model. I have a Page model that acts_as_tree. I''d like the URLs to look something like this: http://localhost/about-us/staff/jeff or, another example... http://localhost/what-we-do/products/our-great-cms/features/faqs/ So, as many sub-nodes the user creates,

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless

I''m trying to call the postback generator on rails 0.9.5. I''ve installed the postback tarball into gems/1.8/gems/rails-0.9.5/generators/postback as it seems like it is supposed to be. At least, I installed the login generator the same way and it works. But when I try to run it, I get this: [carl@e236014 test]$ ruby script/generate postback

Hello, I''m working with scaffold generated controller test code for handling GET requests. Address is the model being tested. Address belongs_to Company, Company has_many addresses.
