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.

\<%= error\_messages\_for ‘user’ %\>  
\<%= error\_messages\_for ‘user\_adress’ %\>  
\<%= error\_messages\_for ‘user\_account’ %\>

 Please enter your data: 

```
<% 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 %\>

  

email:  
\<%= form.text\_field :email, :size =\> 40 %\>

  

username:  
\<%= form.text\_field :username, :size =\> 40 %\>

  

password:  
\<%= form.password\_field :password, :size =\> 40 %\>

  

passwort  
confirmation:  
\<%= form.password\_field :password\_confirmation, :size =\> 40 %\>

  
\<% end %\>   

```
<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 %>

```

  

```
<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:</

```

label\>  
\<%= form.text\_field :account\_number, :size =\> 40 %\>

  
\<% end %\>   

\<%= submit\_tag “Register”, :class =\> “submit” %\>

This creates 3 forms, but no submit tag in any of them.

Try using this:

form\_for :user, @user, :url =\> {:action =\> :new} do |form|  
#…your fields for user

fields\_for :user\_address, @user\_address do |fields|  
#…your fields for user\_adress in the following form:  
# fields.textarea (arguments)  
end

fields\_for :user\_account, @user\_account do |fields|  
#same as for user\_adress  
end

\<%= submit\_tag “Register”, :class =\> “submit” %\>  
end

:user is the class of the object of interest  
@user is an actual instance (which could have another name like  
@new\_user)  
:url points the form to it’s target

same for the fields\_for, but subforms do not get a target.

Have Fun

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.

Please consider that all Rails operations are stateless. You need to  
instantiate a new User in def new. You will find the contents of the  
form via params(:user).

Try:

def new  
@user = User.new(params(:user))  
@user.address.build(params(:user\_adress))  
@user.account.build(params(:user\_account))  
if @user.save!  
flash[:notice] = ‘Registration was successful.’  
redirect\_to :action =\> ‘index’  
else  
render :action =\> ‘register’  
end  
end

I hope, you get the point, i can’t check the code right now.

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:

\<%= error\_messages\_for ‘user’ %\>

 Please enter your data: 

```
<% 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:

  
\<% fields\_for :user\_account, @user\_account do |fields| %\>  

credit institution:  
\<%= fields.text\_field :bank, :size =\> 40 %\>

  

bank code:  
\<%= fields.text\_field :bank\_code, :size =\> 40 %\>

  

account number:\</  
label\>  
\<%= fields.text\_field :account\_number, :size =\> 40 %\>

  
\<% end %\>

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

<% end %>

```

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
