Ruby on Rails Devise code after login

Question

I have an RoR app using Devise for logins. There is some code that is executed when a new User record is created, by being put in the user.rb file as an after_create call/m

Answer 1

I found that using the Devise Warden hook cleanly allowed after login event trapping by looking for the ":set_user" :event.

In user.rb:

class User < ApplicationRecord
  Warden::Manager.after_set_user do |user, auth, opts|
    if (opts[:scope] == :user && opts[:event] == :set_user)
      # < Do your after login work here >
    end
  end
end

Answer 2

Just subclass Devise's sessions controller and put your custom behaviour there:

# config/routes.rb
devise_for :users, :controllers => { :sessions => "custom_sessions" }

And then create your controller like this:

# app/controllers/custom_sessions_controller.rb
class CustomSessionsController < Devise::SessionsController
  before_filter :before_login, :only => :create
  after_filter :after_login, :only => :create

  def before_login
  end

  def after_login
  end
end

Answer 3

I think this is an duplicate question. Yes you can execute code after every successful log in. you could write the code in your ApplicationController. Also have a look at http://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-in. Also, check out How to redirect to a specific page on successful sign up using rails devise gem? for some ideas.

You can do something like:

def after_sign_in_path_for(resource_or_scope)

end

You could also inherit from devise session's class and use after_filter for logins.
