Why does a helper "devise_controller?" return false for my code?

[Nykeriab]

Why is helper? devise_controller? returns false for the following code:

class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
layout :resource
protected
def resource
  if devise_controller?
    #"admin"
    puts "admin"
  else
    #"application"
    puts "app"
  end
end
end

And in the browser line, it's a " http://127.0.0.1:3000/admin/review ♪

file routes.rb:

 Rails.application.routes.draw do
  get 'admin/show'
  get 'admin/upload'
  get 'admin/review'
  get 'welcome/index'
  get 'welcome/portfolio'
  get 'welcome/about'
  get 'welcome/contact'
  get 'welcome/blog'
  get 'welcome/review'
 end

And for the rest of the routes get 'admin/show' and get 'admin/upload', the helper gives true...

Updating

That's the kind of problem. Added to ApplicationController filter

before_filter :my_filter, unless: :devise_controller?
def my_filter

if params['controller'] == 'admin'

render layout: "admin"

end

end

But the substantive question remains - why layout Does it work the same way with malfunctions?

Method devise_controller? Just checking if your class is inherited. DeviseController

def devise_controller?
   is_a?(::DeviseController)
end

You've got a controller coming from you. ActionController::Baseso the condition cannot always be met. In order to verify the authentication, it is best to useper Devise: user_signed_in? and current_user♪ If you need to change the layout regardless of whether the user is authenticated or not, just change it to render it (as you did in the Innovation).
