i want to modify the tutorial 5.

now, i have a Project -> extends Page, that has a Student tab, where i can add some students. and i have a Student.php -> extends DataObject.

each student is a Student DataObject.

when i come to my project page, i want to display all students.

i suppose, i need a function in Project.php that returns all the Student datafields...
can someone show me how to write such a function?


in the Project.Php i have:

   static $has_one = array(
      'Students' => 'Student'

so should i use in my template:

<% control Students %>
... some html
<% end_control %>

but this doesn't work...

from a project holder template, you could write:

<% control Children %>
<% control Students %> //or <% control MyStudent %> if your variables match the tutorials code.
<li>$FirstName $Lastname</li>
<% end_control %>
<% end_control %>

this works in 2.2.3, but havent tried in 2.3rc1
