sign_in method for backend sign in

[nicolasiensen]

I want to sign in users with Casino after they successfully submit the sign up form.

Something like the Devise's sign_in method.

Thoughts?

As CASino does not support user creation (sign up), only login (sign in), I assume you want to do this in another app. You can use the API to sign the new user in, check #38 and #40 for an example.

I'm reusing LoginCredentialAcceptor to auto login users. In my case users are signing up with Devise, after sign up they are redirected to an action I built in UsersController#sign_in.

This action receives username and password as get parameters , and deal with LoginCredentialAcceptor to login the signed up user.

I also had to include CASino::ProcessorConcern::LoginTickets in the top of the controller.

For future visitors, here's a more up-to-date example using the ActiveRecord authenticator:

class RegistrationsController < Devise::RegistrationsController
  include CASino::SessionsHelper

  private

  def sign_up(resource_name, resource)
    return unless params.has_key?(:service)
    data = { authenticator: 'ActiveRecord', user_data: { username: resource.email }}
    sign_in(data)
  end

  # Prevents render/redirect conflicts between Devise & CASino, also makes the
  # service_with_ticket_url available for Devise to follow after registration.
  def handle_signed_in_with_service(tgt, options)
    if !service_allowed?(params[:service])
      @service = params[:service]
      render 'casino/sessions/service_not_allowed', status: 403
    else
      @url = acquire_service_ticket(tgt, params[:service], options).service_with_ticket_url
    end
  end

  def after_sign_up_path_for(resource)
    params.has_key?(:service) ? @url : super
  end
end

In order for this to work you'll need to ensure the service param is forwarded through the registration pipeline (e.g., registration link on the login page and the following registration form tag). I'm sure this example can be improved but it should give you a decent starting point.

Edit: Make sure you're only passing params[:service] and and not the entire params hash in your devise links/form tags. Otherwise you'll break devise as your params hash content will override anything you enter into the forms.
