I have implemented the idiom described in this resource
# /app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
before_filter do |controller|
redirect_to new_login_url unless controller.send(:logged_in?)
end
After a successful sign-in, how can I:
- Determine if the signing in process was successful,
- Redirect the user to the requested controller action?
- Implement the login-process via AJAX and JSON?
Additionally, I am encountering the following Error Message:
uninitialized constant ApplicationController::LoginFilter
When trying out a more complex solution from 6.2 Other Ways to Use Filters which involves modifying my Controller structure as follows:
# /app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
before_action :set_return_path, LoginFilter
def set_return_path
return if devise_controller?
session['user_return_to'] = request.url unless current_user
end
class LoginFilter
def self.filter(controller)
unless controller.send(:logged_in?)
controller.flash[:error] = "You must be logged in"
controller.redirect_to controller.new_login_url
end
end
end
end
Thank you,
