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, h开发者_Python百科ow can I add specific data of the form to this model. Where is the UserController of devise located?

Thanks in advance!

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

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

It's not very clear from your question, but I'm assuming your Devise model is User and you created another model Profile that belongs to user.

You'll need to create a controller for your User model with rails g controller users.

You'll also need to generate the views for your users with rails generate devise:views so that the user can add profile info when he's creating his account.

From there, it's just like any other model: create a user and profile instance and link the two. Then, in controllers, use current_user.profile to access the current user's profile.

Note that if you're going to manage users this way, you'll need to remove the :registerable module from the User model (also read https://github.com/plataformatec/devise/wiki/How-To:-Manage-users-through-a-CRUD-interface)

Another way in order not to put building resource in the view is to rewrite the devise controller and to be exact, the new method, all u need to do is to change it to:

 def new
   build_resource({})
   resource.build_profile 
   respond_with self.resource
 end
