Question

(Disclaimer: I am very new to rails)

This plugin looks like it will be a great fit for my app, but I am
having a hard time getting it to work. I am using it with authlogic, I
am not sure if that is the problem, but it seems like it may be.

When I try an access a page that my admin role should have access to I
get this:

Processing CompaniesController#show (for 127.0.0.1 at 2010-02-12

I have this in my User model
def role_symbols
(roles || []).map {|r| r.name.to_sym}
end

But it doesn’t seem to be calling that. I think that may be the
heart of the problem, but I am also wondering if it has anything to do
with the user_sessions?

Also this is what my application_controller looks like:

 helper_method :current_user_session, :current_user
 filter_parameter_logging :password, :password_confirmation

  before_filter :set_current_user
  protected
  def set_current_user
    Authorization.current_user = current_user
  end

  def current_user_session
    return @current_user_session if defined? (@current_user_session)
    @current_user_session = UserSession.find
  end

  def current_user
    return @current_user if defined?(@current_user)
    @current_user = current_user_session && current_user_session.record
  end

  def store_location
    session[:return_to] = request.request_uri
  end

  def redirect_back_or_default(default)
    redirect_to(session[:return_to] || default)
    session[:return_to] = nil
  end


Here is my authorization_rules.rb

I did capitalize the Admin to reflect that:

authorization do
   role :guest do
    has_permission_on :user_sessions, :to => [:create, :update]
   end

   role :Admin do
     has_permission_on :companies, :to => [:index, :show]
   end
 end 

If you have any ideas I would greatly appreciate it. Thanks.

Answer 1

Apparently the application loads the rules of table roles properly, but don’t load the config/authorization_rules.rb file correctly. Please check the file, his name and the syntax used.

Try to use the privileges section in authorization_rules.rb; like this:

privileges do
  privilege :manage, :includes => [:create, :read, :update, :delete]
  privilege :read, :includes => [:index, :show]
  privilege :create, :includes => :new
  privilege :update, :includes => :edit
  privilege :delete, :includes => :destroy
end

And what about the Companies controller?

Good luck.
