title: An example on how to embed forms in Symfony
body: <p>I am using Symfony 1.3.2 with Propel ORM on Ubuntu 9.10.</p>
  
  <p>I have a user profile table, which has many other tables linked to it (i.e. user_profile.id is a FK in many other tables.</p>
  
  <p>My db schema looks something like this:</p>
  
  <pre><code>user_profile:
    _attributes: { phpName: UserProfile }
    id: ~
    guard_id:  { type: integer, foreignTable: sf_guard_user, foreignReference: id, required: true }
    address:   { type: longvarchar, required: true }
  
  vehicle_type:
    _attributes: { phpName: VehicleType }
    id: ~
    name: { type: varchar(32), required: true }
  
  
  user_vehicle:
    _attributes: { phpName: UserVehicle }
    id: ~
    user_id:  { type: integer, foreignTable: user_profile, foreignReference: id, required: true }
    vehicle_type: { type: integer, foreignTable: vehicle_type, foreignReference: id, required: true }
    license_plate:     { type: varchar(16), required: true }
  
  
  user_child:
    _attributes: { phpName: UserChild }
    id: ~
    user_id:  { type: integer, foreignTable: user_profile, foreignReference: id, required: true }
    gender:   { type: boolean, required: true }
    name:     { type: varchar(32), required: true }
  </code></pre>
  
  <p>I would like to embed the other objects that link to the user profile object, in the user profile form, so that when I am performing CRUD on a user profile form, the related objects (e.g. UserVehicle, UserJob are also CRUD at the same time as the user profile object).</p>
  
  <p>I need a simple snippet that will show how to:</p>
  
  <ol>
  <li>Embed the various related objects (i.e. UserVehicle, UserChild) into the UserProfile form</li>
  <li>Create/Update/Delete the various related objects as the operation is being carried (please note, a user can have more than 0-N vehicles or children assigned to them</li>
  </ol>
