Rails check if Devise has any errors?

I am looking for a way to check if Devise has any errors (invalid credentials etc.) for a before_action method in my ApplicationController. There is code in that method that I need only to run if Devise has no errors.

class ApplicationController < ActionController::Base
   before_action :foo

   def foo
      if !devise_errors?
   end
end

You can check credential errors like this:

class ApplicationController < ActionController::Base
  before_action :foo

  def foo
    if !devise_errors?
  end
  ..
  private

  def devise_errors?
    login_params = devise_parameter_sanitizer.sanitize(:sign_in)
    email = login_params.dig(:email)
    password = login_params.dig(:password)
    user = User.find_by(email: email)
    return true if user.blank?

    !user.valid_password?(password)
  end
  ..
end

Do you mean sign in errors? Wouldn't you only need this in the session controller?

You could check the flash messages...

But you might be better off checking in Warden:

Warden::Manager.warden_callback do |user, auth, opts|
  # code 
end
