Saving multiples of the same object within Ruby On Rails

Question

I've got an organisation database table which holds the following fields:

organisationid, organisationname, organisationaddressid, mainadminname, mainadminaddressid.

The two address ids are pointers to two records within the address database table. The address database table conatins the following fields:

addressid, addressline1, addressline2, addresstowncity, addresspostcode.

So when I create new organisation I want to capture the following information:

organisationname
organisationaddressline1
organisationaddressline2
organisationaddresstowncity
organisationaddresspostcode
mainadminname
mainadminaddressline1
mainadminaddressline2
mainadminaddresstowncity
mainadminaddresspostcode

And when I save this information I want to create 1 organisation record and two address records.

I'm at a loss on how to do this in ROR!

Any suggestions gratefully recieved.

Thanks for your time

Not quite standard looking rails column names, so I'm guessing you may be working with a legacy DB, at any rate:

Assuming that your Organization model was something like this:

belongs_to :organization_address, :class_name => 'Address', :foreign_key => 'organisationaddressid'
belongs_to :main_admin_address, :class_name => 'Address', :foreign_key => 'mainadminaddressid'

# See http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html
# Make the organization accept nested attributes for the addresses
accepts_nested_attributes_for :organization_address, :main_admin_address

Your form would probably look something like this with fields_for the different addresses:

<% form_for Organization.new do |f| %>
  <%= f.text_field :name %><br />
  <% fields_for :organization_address do |oaf| %>
    <%= oaf.text_field :addressline1 %><br />
    <%= oaf.text_field :addressline2 %><br />
    ...
  <% end %>
  <%= f.text_field :name %><br />
  <% fields_for :main_admin_address do |maaf| %>
    <%= maaf.text_field :addressline1 %><br />
    <%= maaf.text_field :addressline2 %><br />
    ...
  <% end %>
<% end %>

After that, in your controller

@organization = Organization.new(params[:organization])
@organization.save

Should save the organization model as well as the two address models.
