Validation always fails on all fields - ruby-on-rails

Question

I'm on Rails 3. I have a model called Client that has name, phone and email. My model file looks like this:
class Client < ActiveRecord::Base
belongs_to :salon
belongs_to :address
validates_presence_of :name
validates_presence_of :phone
validates_presence_of :email
accepts_nested_attributes_for :address
attr_accessible :address_attributes
end
As you can see, name, phone and email are all required. When I go to the form where I'm supposed to be able to create a new Client and submit it, all three validations fail, no matter what I put in the fields. Here is my form file:
<%= form_for(#client) do |f| %>
<% if #client.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#client.errors.count, "error") %> prohibited this client from being saved:</h2>
<ul>
<% #client.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%= f.hidden_field :salon_id, :value => Salon.logged_in_salon.id %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :phone %><br />
<%= f.text_field :phone %>
</div>
<div class="field">
<%= f.label :email %><br />
<%= f.text_field :email %>
</div>
<%= f.fields_for :address do |address_form| %>
<div class="field">
<%= address_form.label :line1 %><br />
<%= address_form.text_field :line1 %>
</div>
<div class="field">
<%= address_form.label :line2 %><br />
<%= address_form.text_field :line2 %>
</div>
<div class="field">
<%= address_form.label :city %><br />
<%= address_form.text_field :city %>
</div>
<div class="field">
<%= address_form.label :state_id %><br />
<%= select("client[address]", "state_id", State.all.collect {|s| [ s.name, s.id ] }) %>
</div>
<div class="field">
<%= address_form.label :zip %><br />
<%= address_form.text_field :zip %>
</div>
<% end %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Here's my create action:
def create
#client = Client.new(params[:client])
respond_to do |format|
if #client.save
format.html { redirect_to(#client, :notice => 'Client was successfully created.') }
format.xml { render :xml => #client, :status => :created, :location => #client }
else
format.html { render :action => "new" }
format.xml { render :xml => #client.errors, :status => :unprocessable_entity }
end
end
end
Any idea why this is happening?

Answer 1

It's because you set :address_attributes as the only accessible attribute. Change
attr_accessible :address_attributes
to
attr_accessible :address_attributes, :name, :phone, :email
or don't use mass assignment.
