Profile model for Devise users?

I want to extend the sign up form of my devise installation. I created a Profile model and am asking myself now, how can I add specific data of the form to this model. Where is the UserController of devise located?

Thanks in advance!

Solution 1:

Assuming you have a User model with a has_one Profile association, you simply need to allow nested attributes in User and modify your devise registration view.

Run the rails generate devise:views command, then modify the devise registrations#new.html.erb view as shown below using the fields_for form helper to have your sign up form update your Profile model along with your User model.

<div class="register">
  <h1>Sign up</h1>

  <% resource.build_profile %>
  <%= form_for(resource, :as => resource_name,
                         :url => registration_path(resource_name)) do |f| %>
    <%= devise_error_messages! %>

    <h2><%= f.label :email %></h2>
    <p><%= f.text_field :email %></p>

    <h2><%= f.label :password %></h2>
    <p><%= f.password_field :password %></p>

    <h2><%= f.label :password_confirmation %></h2>
    <p><%= f.password_field :password_confirmation %></p>

    <%= f.fields_for :profile do |profile_form| %>
      <h2><%= profile_form.label :first_name %></h2>
      <p><%= profile_form.text_field :first_name %></p>

      <h2><%= profile_form.label :last_name %></h2>
      <p><%= profile_form.text_field :last_name %></p>
    <% end %>

    <p><%= f.submit "Sign up" %></p>

    <br/>
    <%= render :partial => "devise/shared/links" %>
  <% end %>
</div>

And in your User model:

class User < ActiveRecord::Base
  ...
  attr_accessible :email, :password, :password_confirmation, :remember_me, :profile_attributes
  has_one :profile
  accepts_nested_attributes_for :profile
  ...
end

Solution 2:

To complement mbreining's answer, in Rails 4.x you'll need to use strong parameters to allow nested attributes to be stored. Create a registration controller subclass:

RegistrationsController < Devise::RegistrationsController

  def sign_up_params
    devise_parameter_sanitizer.sanitize(:sign_up)
    params.require(:user).permit(:email, :password, profile_attributes: [:first_name, :last_name])
  end
end
