Log a user into their subdomain after registration with Rails and Devise

Question

I\'m using Devise for authentication in my Rails 3 app. The application uses PostgreSQL schemas and the Apartment gem to facilitate multi-tenancy.

Answer 1

Override the devise session controller.

Create a file with the exact path app/controllers/devise/sessions_controller.rb

Override the sessions_controller class in that controller. Paste in the code found at the link. https://github.com/plataformatec/devise/blob/master/app/controllers/devise/sessions_controller.rb

class Devise::SessionsController < DeviseController
 # copy-paste the devise session controller below.
 ...
end

Edit the create action to suit your needs.

def create
  self.resource = warden.authenticate!(auth_options)
  set_flash_message(:notice, :signed_in) if is_flashing_format?
  sign_in(resource_name, resource)
  yield resource if block_given?
  respond_with resource, :location => after_sign_in_path_for(resource)
end

I'm looking to see if I can figure out how exactly to make this work, but I know for sure that the result you want is attainable by overriding the devise session controller.

EDIT

If you are using cross-subdomain cookies, you could enforce the subdomain session with a before_filter. For example

before_action do 
    redirect_to root_path, alert: 'That subdomain does not belong to you' if request.subdomain != current_user.subdomain
end
