Rails multiple registration paths with Devise - ruby-on-rails

Question

I'm using devise in rails, and I'm trying to create a second registration path, the default registration path for users (which works perfectly), and a second registration path whereby a user registers and creates a project in a single action as a "Getting Started" action (Think Freelancer.com or any marketplace whereby non-users can register and create their first project in one action).
I've gone through so many threads but they all seem to want to replace the existing registration action. I want to keep the existing registration action and either add a getting_started_new and getting_started_create actions to the existing User::Registration controller, or create a new GettingStarted Controller with methods for new and create that would then allow the nested form (for a user and their new project).
My latest iteration looks something like this:
routes.rb
devise_for :users
resources :users do
resources :projects
end
devise_scope :user do
get "getting_started" =>'getting_started#new'
post "getting_started" =>'getting_started#create'
end
getting_started_controller.rb
class GettingStartedController < Devise::RegistrationsController
def new
#user = User.new
#user.projects.build
end
def create
#user = User.new(getting_started_params)
redirect_to root, notice: "Done"
end
private
def getting_started_params
params.require(:user).permit(:first_name, :last_name, :phone, :password, :email, projects_attributes: [:user_id, :project_type_id, :name, :industry_id, :description, :budget_id, :project_status_id, feature_ids:[], addon_ids:[]])
end
end
But when I try and actually submit the form, it loads the getaction from the new controller, and the post action from the devise registration controller.

I realise that devise does a whole bunch of other stuff besides simply recording the user data, so it may be better to rather move these actions to the Devise User::RegistrationController, and then tweak the accepted params. But how do you override Devise so that it doesn't auto use the devise create method the second you click the submit button, and would instead use a getting_started_create action?

Answer 1

First off getting started is a pretty horrible name for a controller since it is not a noun. You can't say a getting started. So lets change it to QuickstartsController.
Lets setup the routes for this resource:
Rails.application.routes.draw do
# These are your "normal" devise routes
devise_for :users
# This is the mapping for the "quickstart" routes
devise_for :quickstarts,
class_name: 'User',
only: [],
controllers: { registrations: 'quickstarts' }
# These are the actual routes for quickstarts
devise_scope :quickstart do
get "/quickstarts/new", to: "quickstarts#new", as: :new_quickstart
post "/quickstarts", to: "quickstarts#create", as: :quickstarts
end
end
Whenever you are overriding a library controller it is important to take some time to study how the class you are superclassing actually works.
If you look at the Devise controllers almost all the actions have a line like:
yield resource if block_given?
Which lets you tap into the flow of the original implementation by calling super with a block:
class QuickstartsController < Devise::RegistrationsController
# GET /quickstarts/new
def new
# This block is passed to the super class implementation:
super do |resource|
resource.projects.build
end
end
# POST /quickstarts
def create
# You can pass a block here too if you want.
super
end
private
# This should redirect to the newly created project
def after_sign_up_path_for(resource)
polymorphic_path( resource.projects.last )
end
# This is the method Devise devise calls for the params.
def sign_up_params
# Don't write your params sanitiation on one line! Its not cool.
params.require(:user)
.permit(
:first_name, :last_name, :phone, :password, :email,
projects_attributes: [
:user_id, :project_type_id, :name,
:industry_id, :description, :budget_id,
:project_status_id,
feature_ids:[],
addon_ids:[]
]
)
end
end
But how do you override Devise so that it doesn't auto use the devise
create method the second you click the submit button, and would
instead use a getting_started_create action?
Point the form to the correct controller - by passing the url option to form_for.
app/views/quickstarts/new.html.erb:
<h2>Getting Started</h2>
<%= form_for( resource, as: :user, url: quickstarts_path ) do |f| %>
<%= devise_error_messages! %>
<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true %>
</div>
<div class="field">
<%= f.label :password %>
<% if #minimum_password_length %>
<em>(<%= #minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "off" %>
</div>
<div class="field">
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation, autocomplete: "off" %>
</div>
<fieldset>
<legend>Project</legend>
<% f.fields_for :projects do |pf| %>
<%# ... %>
<% end %>
</fieldset>
<div class="actions">
<%= f.submit "Sign up" %>
</div>
<% end %>
