I'm using Devise as the authentication mechanism for my app.
I want to add additional information to my user model, like User statistics, profile pic , and other relevant information about the user.How to achieve this?.
Even after creating "rails g devise : views" it creates only the views which I can customize it doesn't give me of its controllers to edit.

Else can I edit the devise gem itself to fit my requirements ?
I have never tried to customize a GEM. Any links to start with customizing a existing gem?

Devise itself is a Rails engine and you can override any of its functionality by creating a copy of the file you wish to change in your local directory. When Rails begins to look for an appropriate controller for a request, it will first check the local application, then vendor/gems, and then the loaded gems themselves.

In the case of Devise, they mention that modifying controllers should be done in this way:

Configuring controllers

If the customization at the views level is not enough, you can customize each controller by following these steps:

1) Create your custom controller, for example a Admins::SessionsController:

class Admins::SessionsController < Devise::SessionsController
end

2) Tell the router to use this controller:

devise_for :admins, :controllers => { :sessions => "admins/sessions" }

3) And since we changed the controller, it won’t use the "devise/sessions" views, so remember to copy "devise/sessions" to "admin/sessions".

Remember that Devise uses flash messages to let users know if sign in was successful or failed. Devise expects your application to call "flash[:notice]" and "flash[:alert]" as appropriate.
