I have added roles and roles_users table and updated the model so that my users can have multiple roles. ("Admin" role does always have id = 1). I have added these methods to my application controller. <code> helper_method :is_admin? helper_method :is_user? def is_admin? if @session[''user''] @session[''user''].roles.find(1) else false end end def is_user? !@session[''user''].nil? end </code> The problem is t...

Hi all I know that I can define methods in e.g. the application controller and make them available to the helpers using helper_method(), but how can I make them available in the models?

Newbie to RoR -- as a long time Java Struts/etc. guy it is an awesome tool! I have implemented some basic login/session stuff with the help of a great tutorial, props to the author ( http://www.aidanf.net/rails_user_authentication_tutorial). I have a trivial instance method in ApplicationController, which just grabs the User object from the session. def current_user session[:user] end

Hi all I have followed this tute: http://hivelogic.com/articles/2005/12/01/ruby_rails_lighttpd_mysql_tiger to get rails running and all is fine except for getting: undefined method `redirect_to'' when I load my test page.

Hello, I recently updated Rails to 3.0.5. The very same code that worked on 3.0.3 now gives error.

Probably asked and answered, but... Why are controller private methods inaccessible inside the block passed to render :update ?

If I''m writing code in a template and I want to refer to the name of the template itself so that I can pass it to a helper method, is there a built-in variable (like controller_name or action_name) that I can use. Assume x.rhtml and in this template I have helper_method(). I want to pass "x.rhtml" into helper_method without hardcoding it. Do I have access to the _currently rendering_ template name? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

Hi, I have a utility function repeated in both my helper and my controller. Not DRY. I have this repetition because other functions in the helper and in the controller both use the utility function. Where do I put this function so that both the helper and controller can access the function? Mayber there is a different solution? Thanks, Peter

All, Is it possible for a view to call back to a controller method? If so, what is the syntax? === details I have a list view that I want to filter out inactive rows based on several table fields being zero, old, etc. It would seem I should create a "filtered" method in the controller (which I have done). Then invoke if from the view like: for row in @rows continue if row.filtered

Hi all, I have defined the following method in both application.rb and application_helper.rb: def still_logged_in? !session[:user_id].nil? end This method is called in a before_filter in my application.rb, as well as in my layout/application.rhtml and view/user/login.rhtml (for showing a login / logout button, etc.) I had to put it both places, otherwise I would get an

I want a method to be accessible from everywhere in my app (it''s a Gaussian RNG) - I''ve already put them as protected methods in application.rb but that would only allow them to be accessed from controllers.
