Profile model for Devise users?

Question

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

Answer 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.

  
Sign up

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

    
<%= f.label :email %>
    
<%= f.text_field :email %>

    
<%= f.label :password %>
    
<%= f.password_field :password %>

    
<%= f.label :password_confirmation %>
    
<%= f.password_field :password_confirmation %>

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

      
<%= profile_form.label :last_name %>
      
<%= profile_form.text_field :last_name %>
    <% end %>

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

    

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

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
