Devise: Associated Model on Sign Up: Can't mass-assign

Question

I setup Devise on User model with its default options.

I also have a Company model that needs to add data added whenever a user registers. A company owner setups a User to login with and a Company profile, both in the same form.

I setup Company model with has_many :users and User with has_one :company, but I keep getting Can't mass-assign protected when submitting the form. I followed Profile model for Devise users? and others from Stackoverflow, but no luck.

How can I setup the User and Company model to add the necessary data whenever a user registers? User data to User and company data to Company.

Answer 1

How I got it working:

My User model has:

attr_accessible :company_attributes

belongs_to :company
accepts_nested_attributes_for :company

My Company model has:

has_many :users

And the new.html.erb from devise/registrations is with the following added:

<% resource.build_company %>
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
[ fields for User ]
<%= f.fields_for :company_attributes, resource.company do |company| %>
[ fields for Company ]
<% end %>
<% end %>
