similar to: Realtime form validation for forms containing collections

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

Granted, I''m still very much a newbie, but after reading an article on AJAX that basically states at one point that just because you can use AJAX doesn''t always mean you should, I have to ask: Why bother contacting the server (even if it is an insignificant amount of bandwidth) to validate the sanity of form data (unless you''re actually validating against something in

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

Hiall, I just tried out InstantRails version 1.3a. After a virgin install and filling the fresh mysql db with my app schema, I tried runningthe app with webrick, only to see the infamous "Lost connection to mysql server" for every action. What is it that I''m doing wrong? I also have mysql 5 installed on my machine, but the service is stopped while experimenting with

Hiall, If I have say 10 tables that i would like to wrap up in 1 view to manipulate data inside these tables, do I then need 10 model.rb files for all 10 tables plus 1 for the view, or do I just need 1 model.rb file for the view ? cheers Martin

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 =>

Hiall, I want to give the action of a form an additional parameters but can''t figure out how to do it. My code looks like this <%= start_form_tag :action => ''create'', next_step => true %> <%= render :partial => ''user_form'' %> <%= render :partial => ''community_form'' %> <%= submit_tag

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

Hiall, Is it possible to organize my model files below app/models into subfolders? E.g. I would like to put admin related models into their own subfolder. This kind of structuring works for controllers and views (scaffolding creates the right subfolder-model mappings), but app/models always stays flat. I''d really like to be able to group my code into logical, well packages :-) Yes, I

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

Hi, For some dataset I have made a histogram, boxplot en qqplot. http://r.789695.n4.nabble.com/file/n4634093/Naamloos.jpg Investigate the data with the given functions for making QQ-plots and find an appropriate location-scale family for the underlying distribution of this sample. Apart from giving a proper location-scale family, also specify the member of the location-scale family that is

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>,

Hiall, Unfortunately I just can''t find out how to setup a default selected value when using collection_select. My call is like so: <%= collection_select(:consultant, :lastname, @consultants, :id, :lastname, { :selected => @current_consultant.id } ) %> which is not working, I debugged so far that I know that @current_consultant.id contains the correct value. Any tips? cheers

I''m working on a library similar to acts_as_taggable. I''d like it to be a simple, one file drop-in: i.e., put my_library.rb into RAILSROOT/lib/ and have everything work. However, the library requires a controller to render some stuff, so I need to be able to create the controller class, set the routing, and extend the controller at run-time from within my_library.rb. I have code

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

Hello List, while dealing with a questin of 'xiaodao' ( http://r.789695.n4.nabble.com/Problem-with-large-small-numbers-in-knitr-tp4653986.html) I noticed that copying the default inline hook function obtained by knit_hooks$get("inline") into a knit_hook$set(inline = <...>) call turns off exponential fomatting in the resulting .tex file. I used a stripped version of
