Accessing Devise Helper methods inside cell controllers and views about cells HOT 9 CLOSED

Hi, i'm trying the following:

app/cells/main_menu_cell.rb

class MainMenuCell < Cell::Rails
    include Devise::Controllers::Helpers
    helper_method :current_user

    def display
        render
    end
end

display.html.haml

- if user_signed_in?
    %li
        = link_to 'Logout', destroy_user_session_path, :method=>'delete'
- else
    %li
        = link_to 'Login', new_user_session_path

But i'm getting a undefined method `user_signed_in?'

What could I be doing wrong?
Cheers!

Edit:

duh. I get it :). Had to use
helper_method :user_signed_in?

i have the same problems in a rails 3 app and just use signed_in?(:user) for the moment.

when i tried to reproduce the problem in a blank rails 3 app, everything worked fine just by including "include Devise::Controllers::Helpers" in the Cell.

i have no idea right now which part of my app-setup is responsible for this.

Thanks for your inputs. While signed_in?(:user) seems to be working fine. I am getting stuck with resource_name while inserting login form inside cell view. I have included Devise::Controllers::Helpers in the cell. I am trying to keep the view code as close to devise generated view code as possible. Hence I am not directly using user model.

Did you happen to face that problem?

Apart from "include Devise::Controllers::Helpers", inserting Devise::Controllers::Helpers.define_helpers(User) helps me access rest of the devise helper methods. Not sure if this is the best way or the cleaner way to access devise helper methods.

I got it working by calling

helper_method :current_user

and that's what José recommended, too!

Thanks it works great... looks much cleaner too..

hey,

did you try with a fresh rails 3 app? it's working without any extras, just include
include Devise::Controllers::Helpers
you can try the example app here: https://github.com/mixr/cells_devise

Hi,

Yep I tried and yes it indeed works without any additional line... Its kind of strange because now when I run my app after removing "helper_method :current_user" its recognizing user_signed_in? method. I have still not figured out why it was giving me error earlier. But good news is that it now works with one line code and thats 50% improvement over 2 lines :-) Thanks a ton.

thax!
class TransactionWidget < Apotomo::Widget
include Devise::Controllers::Helpers

helper_method :current_user

did the trick!
