how can i get the session_id inside application_controller. I am creating helper methods here in this controller to set session and read them later and I am able to read all session variables, cookies etc from the application_controller. The only exception is
session[:session_id] (variations tried - session[:id], session["id"], session["session_id"]
and request.session_options[:id])
But none of these provide session_id value.
In my views session[:session_id] works fine. But in the application controller this is just not working.
Any help would be appreciated. I am obviously doing something wrong here.
Did you forgot before_filter? It's works for me.
class ApplicationController < ActionController::Base
protect_from_forgery
before_filter :catch_session_id
def catch_session_id
binding.pry
end
end
14: def catch_session_id
=> 15: binding.pry
16: end
[1] pry(#<WelcomeController>)> session[:session_id]
=> "a7eca9eaaf21cff74c0d21713fcaad09"

I am using devise. In a view partial, I have:
<%= simple_form_for resource, :as => :user, ...
In my application helper:
# #see http://stackoverflow.com/questions/4541075/what-is-the-devise-mapping-variable-and-how-can-i-include-it
def resource_class
devise_mapping.to
end
# #see http://stackoverflow.com/questions/4081744/devise-form-within-a-different-controller
def resource_name
:user
end
def resource
# with some controllers (homepage, static, this method is called)
# with other controllers (Item, it's not called: I don't see the abort call)
abort('should stop here')
#resource ||= User.new
end
def devise_mapping
#devise_mapping ||= Devise.mappings[:user]
end
On some controllers, my form works fine. On others, I get this error:
Couldn't find Item without an ID
The problem is that the method I have defined is not called. With some controllers, ApplicationHelper.resrouce is called, on others, it's an other method resource (Item.resource ?), and I don't know where it's defined.
How the method resource can be defined elsewhere ? Why is the method resource of my application helper not called on certain pages ?
Note: I am using the gem inherited_resources that defines the method resource. Maybe this create the conflict. But I don't know how the method is inherited
After seeing http://railscasts.com/episodes/230-inherited-resources, it all became clear.
I defined resource in ItemsController:
class ItemsController < InheritedResources::Base
# #see http://stackoverflow.com/questions/16831095/devise-the-method-resource-is-not-called-properly
def resource
# this solves my problem. It looks super wrong tough
#resource ||= User.new
#view_context.resource # tried that, but doesn't work
end
# ...
And now it works. The method resource was being re-defined by the gem for that controller...
I've been trying to get authentication working with devise, and then omniauth, but I haven't been able to get the user session.
In my application controller, I have
class ApplicationController < ActionController::Base
protect_from_forgery
private
def current_user
#current_user ||= User.find(session[:user_id]) if session[:user_id]
end
helper_method :current_user
end
which I got from the updated railscast https://github.com/railscasts/241-simple-omniauth/blob/master/revised/blog-after/app/controllers/application_controller.rb
In my app, I call
<% if current_user %>
but this always errors out as undefined local variable or method 'current_user'
why is this? is it a problem with my application controller, or maybe a session error with rails?
I've got the following initializer:
app/config/initializers/store_location.rb
module StoreLocation
def self.skip_store_location
[
Devise::SessionsController,
Devise::RegistrationsController,
Devise::PasswordsController
].each do |controller|
controller.skip_before_filter :store_location
end
end
self.skip_store_location
end
Relevant parts of my ApplicationController:
class ApplicationController < ActionController::Base
protect_from_forgery
before_filter :convert_legacy_cookies
before_filter :store_location
alias_method :devise_current_user, :current_user
def current_user
# do something
end
private
def store_location
# store location
end
Plus this in
config/environments/development.rb
Foo::Application.configure do
# normal rails stuff
config.to_prepare do
StoreLocation.skip_store_location
end
end
If I let RSpec/Rails run the self.skip_store_location I'm getting the following error:
/foo/app/controllers/application_controller.rb:7:in `alias_method': undefined method `current_user' for class `ApplicationController' (NameError)
If I remove the call, everything is back to normal (except the filter is run, as expected). I'm guessing that I mess up dependency loading somehow?
The problem is that you use alias_method before the method is defined in ApplicationController. To fix the problem, move the line
alias_method :devise_current_user, :current_user
below
def current_user
# do something
end
It's a bit misleading that the error appears when running skip_store_location. I assume that happens because skip_store_location loads several controllers, and one of them is a subclass of ApplicationController.
I'm having problems displaying data from a separate controller. I have a number of users, each with many pages. I've followed this tutorial with a few minor adjustments.
The error that keeps appearing is:
NoMethodError in SitesController#show
undefined method `page' for #<ActionDispatch::Request:0x00000102452d30>
My routes.rb is as follows:
devise_for :users
resources :users, :only => [:index, :show] do
resources :pages, :shallow => true
end
match '/' => 'sites#show', :constraints => { :subdomain => /.+/ }
root :to => "home#index"
And I have a sites controller:
class SitesController < ApplicationController
def show
#site = Site.find_by_name!(request.page)
end
end
I've also tried:
def show
#site = Site.find_by_name!(params[:site])
end
Which gives a different error.
Am totally stuck trying to figure this out!
Looking forward to your assistance.
Bob
The problem is here: request.page
The request object is of the class ActionDispatch::Request, which does not have a page method.
To track down errors like this, you can try either looking at the docs or messing around in the debugger.
Try running your controller with --debugger enabled.
If you are running Ruby 1.8, install the ruby-debug gem.
If you are running Ruby 1.9, install the ruby-debug19 gem.
Add a debugger call here:
class SitesController < ApplicationController
def show
debugger
#site = Site.find_by_name!(request.page)
end
end
Run your server with the --debugger option.
See what p request.page does. I bet it will have an "undefined method" error, just you see when you try to view that controller action.
If you do a p request.class you can find out what class the object is, and then look up the docs to see how to use it.
I'm upgrading an application from Rails 2 to 3. I use a Rights and Role approach for authentication that worked fine under Rails 2. In my Application Controller (application.rb) I have:
class ApplicationController < ActionController::Base
def check_authentication
unless session[:user]
session[:intended_resource] = request.request_uri
session[:intended_action] = action_name
session[:intended_controller] = controller_name
redirect_to :controller => "sessions", :action => "new"
return false
end
end
def check_authorization
user = User.find(session[:user])
unless user.roles.detect{|role|
role.rights.detect{|right|
right.action == action_name && right.controller == self.class.controller_path
}
}
flash[:notice] = "You are not authorized to view the page you requested"
request.env["HTTP_REFERER"] ? (redirect_to :back) : (redirect_to :controller => "sessions", :action => "new")
return false
end
end
end
In my other controllers I've included a before filter.
before_filter :check_authentication,:check_authorization
I'm getting the following error message, for example, when I go to my Dashboard Controller.
NameError (undefined local variable or method `check_authentication' for DashboardController:0x0000010291a0c0):
Is there something else I need to change or add to make this work in Rails 3?
Thanks,
Aaron
Make sure that your DashboardController is inheriting from ApplicationController i.e. DashboardController < ApplicationController.
Problem solved. Somehow during my upgrade I had a file named application.rb and application_controller.rb in my controllers folder. Both were defined as ApplicationController < ActionController::Base. The code for my "real" Application Controller was sitting in application.rb and not in application_controller.rb, which was empty. A simple copy-n-paste and things were fine. I don't know how that happened. Running the rails_upgrade plugin didn't go as smoothly as planned.
