Question

Assuming that I’m not signed in.
In this case, it displays this flash notice when accessing to actions in mails_controller.

You need to sign in or sign up before continuing.

However, it won’t display in communities_controller.
Why? and How can I fix?

mails_controller.rb

class MailsController < ApplicationController
    before_filter :authenticate_user!
    ....
end

communities_controller.rb

class CommunitiesController < ApplicationController
    load_and_authorize_resource :find_by => :id
    before_filter :authenticate_user!
end

Answer 1

try moving the load_and_authorize_resource line after the before_filter. The load_and_authorize_resource line will raise an exception when it can’t find the resource for member actions which may be happening before you even get to the before_filter line
