Add a profile model with User model - Edit Problem

Hi there,

I used restful authentication to generate the authenticated system, but i still want to add a profile model as a part of user model.

So between user & profile I use has_one association to connect them.

Create - OK But when i want to edit someone's profile, the data not update in sql.

my user model is like this:

has_one :profile attr_accessible :login, :email, :password, :password_confirmation

def profile_attributes=(profile_attributes)     profile_attributes do |attributes|        profile = profile.detect {|p| == attributes[:id].to_i}        profile.attributes = attributes     end   end

My Profile model is like this: belongs_to :user

The migration has the user_id foreign_key set up.

In the view/user/edit.html.erb, i wrote enclosed codes:

<% form_for :user, :url => user_url(@user), :html => { :method => :put } do |f| %>   <p>Email:<br /><%= f.text_field :email, :size => 60 %></p>   <% fields_for "user[profile_attributes]", @user.profile do | p_form| %>     <p>      Name: <%= p_form.text_field :name, :index => nil %>     </p>     <p>      Gender: <%= p_form.text_field :gender, :index => nil %>     </p>     <p>       Birthday: <%= p_form.text_field :birth_on, :index => nil %>     </p>     <p>       Place: <%= p_form.text_field :place, :index => nil %>     </p>     <p>       About Me: <%= p_form.text_field :about_me, :index => nil %>     </p>     <%= p_form.hidden_field :id, :index => nil %>   <% end %>

<%= submit_tag 'Update' %> <% end %>

When I click update button, error says: Couldn't find Profile without an ID

Or Can't mass-assign in a protected attributes in the development log.

Can anyone help me?

You need to iterate through the hash:

profile_attributes do |attributes|

Change to:

profile_attributes.each do |attributes|

Also, be sure to save the profile model.
