similar to: reloading include-modules inside controller not working

I want to overload the = operator for one of the attributes in a model to run a filter on the input. However I can''t do this: def attribute=(data) self.attribute = filter(data) end because that creates an infinite recursive loop. How do I get around this? -- Posted via http://www.ruby-forum.com/.

Is there a way I can read the user agent or something similar to determine whether the person is using IE, Mozilla/Netscape, Opera, Safari, etc? I want to dynamically output the CSS to the browser, but I''d like to change certain things (in this case the widths of some divs since IE adds borders and padding size to the total size of a div unlike firefox). Thanks, - Brent

In my rspec_on_rails controlle rspec, I have this: require File.dirname(__FILE__) + ''/../spec_helper'' describe FooController, "with a foo" do it "should be false" do get ''index'' assigns[:foo].should be_false end end In my controller I have this: class FooController < ApplicationController def index @foo = FALSE end

I have a lot of controllers with virtually identical functionality for most actions. I''ve been using shared behaviours to DRY things up a bit, but I still have to create separate behaviours for each context before I can use the shared behaviours what I have now is a generic file which contains all the behaviours and examples common to all the controllers, and that file gets loaded from

I''m trying to update a table row (i.e. replace a <tr></tr>) using AJAX/RJS but of course this cannot be done in IE (works fine in Firefox). I have googled but have not found any solutions, only a lot of discussion. Does anyone have a solution to this problem? Cheers, Nicholas

Hi, In my test case below, it seems that ''initialize'' is called everytime ''hello'' is called. Is this by design, a bug, or my pilot error? class FooController < ApplicationController def initialize print "\n initialize \n" end def hello print "\n hello \n" end end I

Hello all. Is there a way to stop users from being able to access a controllers methods without affecting the ability of other controllers to use them? i.e FooController def secret #Stuff end end BarController def index redirect_to :controller => ''foo'', action => ''secret'', :id => ''007'' end end But directly

Hi, (This is my first post after months of appreciative lurking...) I''m trying to spec the following conditional controller macro: class ApplicationController < ActionController::Base # turn off session management for robots session :off, :if => lambda {|req| req.user_agent =~ /(Google|Slurp)/i } # ... end My current attempt seems to be quite unsuccessful: 1) when I

Hi! Is it possible to render the action within the after_filter method, or is the rendering performed before? I have something like this: class FooController after_filter :send def a @content=... end def b @content=.. end protected def send send_data(@content,...) end end However, when calling the action a or b, the @content doesn''t get sent, but instead

Hi all, I''m trying to output some info to see what''s happening in a controller during functional tests. Problem: ''print'' only works in the test code, but not in the production code that''s being called by the tests. Example: In FooControllerTest: def test_list print "1: starting" <<----- WORKS FINE get

I''m not sure but I think this is due to the ''modules'' support in the latest beta gems. In some controllers I include small utility classes that only make sense for that controller. Something like this: class SantasLittleHelper < Foo end class FooController < ApplicationController end Where Foo is defined in RAILS_ROOT/lib/foo.rb What I am seeing now

Out of curiosity, I''ve seen the following fail: module Admin describe MyController ... end end But this works fine: describe Admin::MyController .. end Why? Scott

Hello, I want to a select tag, where you can choose a number between 1 and 100. My inital code is based on the examples from Agile Web Development with Rails, and looks like this: view: <%= options = [["Select number of lines", ""]] + RfqLines::LINE_QTY select("rfq_line", "line_qty", options) %> model: LINE_QTY = select_fill def

If you see this error message: undefined method `use_transactional_fixtures='' for Test::Unit::TestCase:Class (NoMethodError) You should check all your dependencies, all the lines containing require and especially require_dependency.

I need to generate some browser-specific code; can I identify which browser is being used from within my RoR code? -- Posted via http://www.ruby-forum.com/.

Hello everyone: Right now I am writing spec on modules, which are provided by my colleagues. Some of the modules actually contain action methods. I tried very hard to spec those action methods in modules. But it seems that the rspec does not allow module spec to ''get'' action like controller does. After I saw the documentation, I then used :behaviour_type=>:controller.
