Rails - Dec 2005 - Parent Child together in input form

Hi all,

I understand how rails is supposed to work when dealing with one entity
input form.

However, when I have a relation between two objects (composition):

Customer(1)  --------> (1)Address

How can you create a inputform where both the properties of a Customer and
Address can be filled in?

Regards,

Harm de Laat

Check the thread
    "managing belongs_to fields in a form"

I posted this very question a few hours ago.

Harm,

Sorry, I misread your post. Your question is different.

I would  simply input the 2 objects independantly in the same form

      customer = Customer.new
      address = Address.new

, build them separately from their parts, link the address to the 
customer and finally save them both.

Thx for the reply!

Do you maybe have an example of this?

How do I do this in de RHTML file?

In JSP i might be able to do something like:

<input type="text" name="<%= <c:out
value="${customer.address.street
}"/></input>

What is the equivalent of the above in RHTML?

Regards,

Harm.

Harn,

You can start from the default scaffold code, and simply extend it:
(caution: untested advice, suggested by a newbie !!)

  def new
    @customer = Customer.new
    @address  = Address.new
  end

  def create
    @address = Address.new(params[:address])
    @customer = Customer.new(params[:customer])
    @customer.address = @address

    if @address.save && @customer.save
      flash[:notice] = ''Member was successfully created.''
      redirect_to :action => ''list''
    else
      render :action => ''new''
    end
  end


For the rhtml, update the view (the _form.rhtml partial) accordingly.
