similar to: Silly question re: scoping of controller actions

I was thinking about having instance variable stored and fetched from session container automatically before calling an action and after the action is finished. Using methodology of accessors it would look like: class MyController < ActionController::Base persistent_attr :person def alfa person = ''John Smith'' # render as usual view alfa.rhtml with anchor

I''ve created an access control module that I''m including in several different controllers. Everything works fine, but I want to allow each controller to override the default login page with something like this: set_login_pages :secure => ''my_login'' In my module, I''ve set up the set_login_pages method like this: def self.included(base)

Can I set an application wide instance variable that is available for all actions...and their views? eg. class ApplicationController < ActionController::Base @current_user = User.find(session[:user_id]) end and everywhere I can call @current_user.id and I can get that object? Even down in the views? I could not get this to work... Thanks in advance, Jeff -------------- next part

I''m preety new at RoR (and programming), I tried a few tutorials, and really like the RoR simplicity, but my knowledge of the framework still isn''t very good (to be true, i understand the basics, but not everything that''s in the tutorials). But still I''d like to create a website which has: - front end interface (with no edit functions) - admin interface

There''s probably a simple answer to this simple problem, but I am trying to figure out how to reference an instance variable within a layout. In the controller, one method corresponds to a view of the same name. Those instance variables in the method can be used in the corresponding view. However, I want my instance variable to be accessible throughout all my views, not just one,

I''ve got an acts_as_tree structure which I want to be able to represent in the URL, with one field identified as the url component. In other words, if I''ve got this: def self.up create_table :nodes do |t| t.column :parent_id, :integer t.column :tag, :string end end and class Node < ActiveRecord::Base acts_as_tree end and what I want the urls to be is something

I want to put a before_filter in application.rb, as follows: before_filter :do_something, :except_controller => [:admin] def do_something(options) options.stringify_keys! unless options[:except_controller].include?(controller_name) # do something useful end end Where I''m blocking is on how to get the ''options'' data in the do_something method. I think I

Wow, I can''t believe that after a few weeks of playing around with Rails I got stuck on something that seems like it should be really simple. How do I display a default welcome page for visitors who are not logged in and send logged in users to the appropriate controller. I am using the login_engine and the user_engine. The two methods I have seen looking at sample code are to stick a

I''m trying to write some tests for the ApplicationController as shared tests that can be run in all of my other controller tests, but am getting a nil.rewrite error. Below is what I have... describe AccountController do it_should_behave_like ''Application controller'' end describe ''Application controller'', :shared => true do it

Hello all, I''m very new to Rails and I love it so far. However, there are some things that aren''t so clear to me. Let''s say a blog post can have many comments, and a comment can only belong to one post. A user can have many posts and many comments as well. (this part makes perfect sense): class Comment < ActiveRecord::Base belongs_to :posting belongs_to :user

Slowly figuring out how to get my SaltedHashLoginGenerator stuff working. The wiki page says to put "before_filter :login_required" in the user (my "user" is "member") controller or in ApplicationController. However, wherever I put it I get NoMethodError. The rest of the SHLG stuff seems to be working... or at least I could get to the signup page, register, and

I am having some problems with variable scoping. I need to be able to set a variable that is accessable by other methods within the class (or instance) (i.e not global). An example is 2 pages that change a class variable: class AjtestController < ApplicationController def initialize @@variable = "init" end def show @display = @@variable @@variable = "change 1"

Can you restric before_filter to specific actions? -- Posted via http://www.ruby-forum.com/.

Hello, my application controller defines before_filter :set_charset def set_charset @headers["Content-Type"] = "text/html; charset=ISO-8859-1" end Everything is fine and accents are rendered correctly in the browser. However, when I call a controller/action from Ajax (Prototype), the charset is not taken in account and accents are garbage displayed (''?''

During one of my controller actions I want to call an external machine before I do anything. It''s not a real web service, more like a REST-style thing where I''ll just be tweaking a servlet running on another machine and sending it some data. Does Rails give me anything to work with for doing that? I read the web service stuff but it''s overkill for what I need. I

If I have several controller actions which have this same line of code (or more), how can I DRY up the line without running into complaints about redirecting or rendering only once? If I put the line in another method in my controller, won''t it think I''m redirecting? I want to dry up lines like this: @listing = Listing.find(params[:id]) def customerview @listing =

Is there a way to authenticate with an IP address? I''m using the LoginGenerator, but would like to bypass the "before_filter :login_required " if a user is in a correct IP range... Anyone know of a solution? Thanks! -- Posted via http://www.ruby-forum.com/.

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

Hi, I have a URL with encoded characters, I want them to be decoded. Is this possible in the routes.rb? e.g. decoding the @params[category] map.connect ''performances/:category'', :controller => ''performance'', :action => ''list_performances'' regards, J?rg
