Problem: 1. ERB and Builder template engines are heavily wired in ActionView::Base 2. Should be optional. If we use different engine - why load all their stuff if not needed? 3. There are template engines which expect files in their own locations and cache them in their own way. For instance a template engine may store templates in a database. These engines don''t need any central source

What''s the best way to set the default value of an optional local variable in a partial template? In the past I''ve used <% foo = default_value unless (defined? foo) %> But http://api.rubyonrails.org/classes/ActionView/Base.html says *not* to use (defined? foo) and instead use (local_assigns.has_key? :foo) thus <% foo = default_value unless (local_assigns.has_key?

Hello all I prefer to use many partials. It makes my code more DRY Also I use rspec, and when I have to test partial with sub partials I have a problem. if I stub render, then my partial will not be rendered. If i do not stub render it tries to render sub partial (and i don''t need this) Not very long googling did not bring the answer, so I made very dirty and IMHO dangerous function

Hi guys, I really like RJS. I think they''ll replace partials in alot of instances. Unfortunately, because they''re automatically used like .rhtml and .rxml and are hard to specifically specify it makes it messy to preserve fallbacks when using them. For instance, using partials instead of rjs, my create method might look like: def create post = Post.new(params[:post]) ...

How could I check the value of an javascript object''s attribute? <div id="new_item_details" style="display:none"></div> <%= link_to_function("Show details...", nil, :id => "show_details") do |page| page.visual_effect(:toggle_blind, :new_item_details) if (page[:new_item_details].style.visibility ==

I am trying to pass the result from a javascript function along with the result from a text_field with form_remote_tag. This is what I have so far, but no go: <% form_remote_tag(:url => {:controller => ''requests'', :action => ''create''}, :with => "''data=''+request()", :update => ''request_sent'' )

I''m not sure what happened, or what change has caused this to happen, but render :partial (or any render for that matter, doesn''t seem to let me set local variables via the local_assigns argument hash. for example <%= render :partial ''edit'', :username => @user.username %> used to allow that username was a local variable in my _edit.rhtml partial

Here is my weird problem. Two models like following: Lexeme id:int name:string Structure id:int ref_id:string meta_id:int Lexeme can have many structure records through foreign key ''ref_id'' in the structures table. And these structure records belonging to one lexeme differs between each other using meta_id. And if Lexeme has structures, then there must be a top_struct whose

All, I want to create a mock action to test a filter in a functional test, e.g.: # Simplified example def test_my_filter # Singleton action def @controller.foo assert # something end ActionController::Routing::Routes.draw do |map| map.connect '':controller/foo'', :action => ''foo'' end get :foo end My log files show that

Does anyone find them useful? I can see them being good in some cases, but I have many exceptions that occur because of expired sessions. I am also not sure if they are really required for pages that require a login to access. The other place that they cause issues is in javascript requests. I am not using the built-in helpers, and all the javascript exists in separate js files. There is ways

I have two classes: a Widget and a User. The User has an id that is referenced in two places on the Widget: owner_id and operator_id. How should I structure that reference for has_many?

I''ve been here before and maybe I''m trying to do something that is not possible. I am trying to include tables that are associated to other tables in the actual include statement but not to the original table call.

I have a problem with a mismatch between RSpec Rails and the actual behavior when using GetText, and would be glad for suggestions how to best solve this.

Hi, how do I solve this in Rails: Lets say I have a User and a Message. Now, a Message is sent from one User to another User, which means that in the Message I have to reference a User twice! This seems to be a problem, if I do not user one-to-many or many-to- many relationships, because it seems to me as if I could reference a Model of the same type only once. However, I would like the Message

Hi, I''m playing around with module instance variables. I can set one up and initialise it when the module is included in a class. What I can''t work out is how I initialise one when a class inherits another class that includes the module. See http://pastie.org/905720 This creates two classes, the first inherits a module that contains an instance variable. The second inherits the

I''m modifying a shopping cart plugin, MinimalCart, and for some reason I can add one item to the cart multiple times, but as soon as I add a second item, all kinds of strange things start happening. An actionview::template error is thrown because a method defined in application_helper is "undefined" What could cause a defined application helper method to all the sudden not be
