设计覆盖会话控制器

Question

I want to add a message when user tries to sign in and it's not confirmed, I want to display this message in notice section, basically devise needs to provide this message to us but I don't see any message in this cases. So I decided to add it manually from sessions controller here is my code:

class SessionsController < Devise::SessionsController

  def new
    super
  end

  def create
    user = User.find_by_email(params[:user][:email])

    self.resource = warden.authenticate!(auth_options)
    set_flash_message(:notice, :signed_in) if is_flashing_format?
    sign_in(resource_name, resource)

    if user.confirmed_at.nil?
      flash[:notice] = "my message here"
    end
    yield resource if block_given?

    respond_with resource, location: after_sign_in_path_for(resource)
  end

end

the problem is flash[:notice] is empty after action is executed, in console I have

   (0.1ms)  begin transaction
   (0.2ms)  commit transaction

how can I display this message?

More simple way to do what are asking about is to add before_filter :confirmation_notice in you application_controller and check whether current_user.confirmed? or not.

ex ::

before_filter :confirmation_notice

def confirmation_notice
  flash[:notice] = "my message here" unless current_user.confirmed?
end

Do not forget to configure your views to show this flash notice.
