3 models in 1 template

hello,

I'd like to get user data in one template.

The relations are: user has_one user_adress user has_one user_account

The following template doesn't save any (valid) data. I think the submit button doesn't work. All 3 models should be validated when save is called.

<div class="shop-form">

  <%= error_messages_for 'user' %>   <%= error_messages_for 'user_adress' %>   <%= error_messages_for 'user_account' %>

  <fieldset>     <legend>Please enter your data: </legend>

    <% form_for :user do |form| %>         <label for="user_first_name">firstname:</label>         <%= form.text_field :first_name, :size => 40 %>       </p>       <p>         <label for="user_surname">surname:</label>         <%= form.text_field :surname, :size => 40 %>       </p>       <p>         <label for="user_birthdate">date of birth</label><br/>         <%= date_select 'user', 'birthdate', :include_blank => true,         :order => [:day, :month, :year], :start_year => 1900, :default => :blank %>       </p>       <p>         <label for="user_email">email:</label>         <%= form.text_field :email, :size => 40 %>       </p>       <p>         <label for="user_username">username:</label>         <%= form.text_field :username, :size => 40 %>       </p>       <p>         <label for="user_password">password:</label>         <%= form.password_field :password, :size => 40 %>       </p>       <p>         <label for="user_password_confirmation">passwort confirmation:</label>         <%= form.password_field :password_confirmation, :size => 40 %>       </p>     <% end %>

  <br/>

    <legend>Your adress:</legend>     <% form_for :user_adress do |form| %>       <p>         <label for="user_adress_street">street:</label>         <%= form.text_field :street, :size => 40 %>       </p>       <p>         <label for="user_adress_nr">number:</label>         <%= form.text_field :nr, :size => 40 %>       </p>       <p>         <label for="user_adress_postcode">postcode:</label>         <%= form.text_field :postcode, :size => 40 %>       </p>       <p>         <label for="user_adress_city">City:</label>         <%= form.text_field :city, :size => 40 %>       </p>     <% end %>

  <br/>

    <legend>Your payment details:</legend>     <% form_for :user_account do |form| %>       <p>         <label for="user_account_bank">credit institution:</label>         <%= form.text_field :bank, :size => 40 %>       </p>       <p>         <label for="user_account_bank_code">bank code:</label>         <%= form.text_field :bank_code, :size => 40 %>       </p>       <p>         <label for="user_account_account_number">account number:</

        <%= form.text_field :account_number, :size => 40 %>       </p>     <% end %>

  <br/>

  <%= submit_tag "Register", :class => "submit" %>   </fieldset>

</div>

there's also a problem in my controller. Neither does it save anything to the database nor validate the models.

The template is register.rhtml. I wrote it as you said.

  def register     @user = User.new   end

  def new     if @user.save       @user.adress = @user_adress       @user.account = @user_account       flash[:notice] = 'Registration was successful.'       redirect_to :action => 'index'     else       render :action => 'register'     end   end

I forgot to say that the relations are dependent.

And not everyone does have an account. So, if there's nothing in the account field, the account shouldn't be saved.

Thanks for your help, I got to the following working code. 2 more questions after the code.

In the controller:

  def register     @user = User.new(params[:user])     @user.time_of_registration = Time.now     @user.user_adress = UserAdress.new(params[:user_adress])     @user.user_account = UserAccount.new(params[:user_account])     if request.post? and @user.save       flash[:notice] = 'Registration was successful.'       redirect_to :action => 'login'     end   end

register.rhtml:

<div class="shop-form">

  <%= error_messages_for 'user' %>

  <fieldset>     <legend>Please enter your data: </legend>

    <% form_for :user, @user do |form| %>       <p>         <label for="user_first_name">First name:</label>         <%= form.text_field :first_name, :size => 40 %>       </p>       ...

      <% fields_for :user_adress, @user_adress do |fields| %>         ...       <% end %>

      <p>If you want to pay using debit, please enter your bank account: </p>       <% fields_for :user_account, @user_account do |fields| %>         <p>           <label for="user_account_bank"> credit institution:</label>           <%= fields.text_field :bank, :size => 40 %>         </p>         <p>           <label for="user_account_bank_code">bank code:</label>           <%= fields.text_field :bank_code, :size => 40 %>         </p>         <p>           <label for="user_account_account_number">account number:</

          <%= fields.text_field :account_number, :size => 40 %>         </p>       <% end %>

      <%= submit_tag "Register", :class => "submit" %>

    <% end %>

  </fieldset>

</div>

The user model:

class User < ActiveRecord::Base

  has_one :user_adress, :dependent => true   has_one :user_account, :dependent => true

  validates_associated :user_account, :user_adress   ... end

The account model:

class UserAccount < ActiveRecord::Base   belongs_to :user

  validates_presence_of :bank, :bank_code, :account_number

  validates_numericality_of ...   validates_inclusion_of ...   validates_format_of ... end

Questions:

Validation of user_account and user_adress looks like "User adress is invalid". I would like to show the errors for the children classes explicitly.

How can I change "validate_presence_of" in UserAccount so that either all or no fields are entered?

Thanks, Luma
