Hiall, I have the following problem: I need to use forms containing collections (i will call them FCC), and I want to construct them dynamically, as I need to deal with quite large forms (more than 600 input fields). The variables @model_name and @field_name contain the proper model and field names as strings, which is enough for "normal" form input fields. (i.e. the "if

Where can I find more information about the new syntax on these: <%- model_class = @product.class -%> <h1><%=t ''.title'', :default => t(''helpers.titles.new'', :model => model_class.model_name.human, :default => "New #{model_class.model_name.human}") %></h1> <%= render :partial =>

Hi everyone, I''m trying to use ajax to update the selected value of a select element. Here''s what I have so far: function RailsModel(model_name) { this.model_name = model_name; } RailsModel.prototype.getAttributeById = function(attribute, id) { Ajax.Request(''/models/get_attribute_by_id/'' + this.model_name + ''/'' + attribute +

Hello everyone! Ive been on rails for the last month or so and really enjoyed this framework. However its very hard to find documentation on how to do things right! For example every beginner after a while realizes that having similar CRUD actions in every controller and views for them is not DRY at all! Few days ago I found http://dereksivers.com/rails-shared-controller.html I quite like his

File_column plugin is great. I need to change the default :store_dir from the dynamic "model_name/attribute_name" to an equally dynamic "client_id/app_id/model_name/attribute_name". In my model I have: class Component < ActiveRecord::Base belongs_to :component_type belongs_to :component_group breakpoint file_column :content, :magick => { :versions

I now have two specs in my rails project which correspond to one rails controller. I can run them individually and they pass, but running them together (either with the rake task just putting both files on the command line): euclid% spec spec/controllers/crud_resource_controller_spec.rb spec/ controllers/crud_resource_controller_with_join_models_spec.rb

I''m trying to get a collection_select generated Drop-down box to display two fields from a table (first name & last name); however, I am having trouble concatenating the symbols. It appears as though any code I put in the 5th argument for collection_select is processed prior to executing the collection_select method. The code executes successfully with 1 symbol in the 5th

I''m doing very well with the Hibbs Rolling on Rails tutorial. I have an easy question for my personal notes. I''m coming up with a simple framework of steps for creating a basic database. It includes the following maxims to make original app creation easy: app_name = MySQL database name SQL_tablename = model_name model_name = controller-name Is this going to work for getting

Hi, I''d like to do a "find_by_sql" without a model (e.g. <model name>.find_by_sql("...")) as the results I get back are a once off special, and I''m happy to handle them as an array. How do I do this? "ActiveRecord::Base.find_by_sql(...)" does not seem to work? Background - At the moment I''m doing within a model <model_name>,

Hi, I''m successfully using the realtime_form_validation plugin from http://railsrtv.rubyforge.org/ However, my forms contain collections, as described in the AWDWR book. Basically my form looks like this. 2004 2005 2006 Question 1 12 13 15 Question 2 9 11 13 I have the following code to generate ids for my input fields.

In ActionDispatch::PolymorphicRoutes, there is a call to build_named_route_call an on line 172 (of latest rails code from github), there is a call to singular_route_key: model_name_from_record_or_class(parent).singular_route_key Now model_name_from_record_or_class returns an ActiveModel::Name object, which is a wrapper to the string class, that returns a string name of the class of an

Hello, I''m working on a rails 3 app for a legacy oracle db. I have a controller that saves object graphs (accepts_nested_attributes_for) but I noticed the post-update JSON response still contains the pre-update values. After some debugging, it appears the database connection is returning stale values (find(), reload(), etc., all return pre-update values; but SQL clients and

I use file_column and it works fine. I tried to change the store_dir to a the path I want my files to be stored and not the default. I stored some images fine. But when I try to reach my images it seems like file_column uses the model_name/attribute_name on the image and not the store_dir I used. How can I change this ? Thanks in advance -- Alexander Antonakakis

Hi! I know that there are other topics about this issue, I read them and I''m always blocked. Here is the error message: undefined method `model_name'' for NilClass:Class Extracted source (around line #30): 27: 28: <h2>Add Translation</h2> 29: 30: <%= form_for @new_trad do |f| %> 31: Locale: <%= f.text_field :locale %> 32: Key : <%=

Hi, I''m doing a <model_name>.update(....) but I''m noticing that my before_update callback is not being called. If I do a find and then a save!, I notice that it is called. The problem with a find and save in my case is that I''m not able to set all my attributes in one shot by saving params["user"] and since I can''t do this, my overloaded

Hi, I cant seem to find the answer to this anywhere so any help/advice is appreciated. Each project has one risk and a risk has a number of has/one belongs to assocations. So what i want to do is in my code loop through all the associations for a risk and display some field information from each as they are pretty similar. So somehting like <% for model_association in project.risks %>

Hi, i got search which shows following error ActionView::Template::Error (undefined method `model_name'' for NilClass:Class): 1: <%= form_for(@employee) do |e| %> 2: EMP ID<%= e.text_field :id %><br> 3: <%= e.submit ''search'', :controller => ''employees'', :action => ''search1'' %>

Community, I have been putting off implementing a Date selector for too long. Tonight, I finally put it in. I made the choice to go with the datebox engine. Once I got it installed and working, I realized I didn''t like the way it required you to call it. Example: <% @dateField = model.date %> <%= date_box %> or... <% @dateField1 = model.date %> <%=

For the longest time PartialRenderer#partial_path has prefixed the prefix of the current controller when it is nested in a module. This hasn''t been a problem (because nesting controllers wasn''t that common) but with 3.1 striving for better engine support, this problem is now larger because all of your controllers for an engine will be nested and it makes doing <%= render
