hello,

I want to create a page for publications, so I created a PubHolder, PubPage and Publication classes as the following:

PubHolder.php

<?php

class PubHolder extends Page {
   static $db = array(
   );
    static $has_one = array(
    );
    static $has_many = array(
    );
    static $icon = "ea/images/treeicons/books";
   static $allowed_children = array('PubPage');
}

class PubHolder_Controller extends Page_Controller {
}

PubPage.php :

<?php
class PubPage extends Page
{
	static $has_many = array (
		'Publications' => 'Publication'
	);
        static $icon = "ea/images/treeicons/book-type";

	public function getCMSFields()
	{
		$f = parent::getCMSFields();
		$manager = new ImageDataObjectManager(
			$this, // Controller
			'Publications', // Source name
			'Publication', // Source class
			'photo', // File name on DataObject
			array(
				'Titre' => 'Titre',
				'Auteur' => 'Auteur',
				'Editeur' => 'Editeur'
			), // Headings
			'getCMSFields_forPopup' // Detail fields (function name or FieldSet object)
			// Filter clause
			// Sort clause
			// Join clause
		);

		// If undefined, all types are allowed. Pass with or without a leading "."
		$manager->setAllowedFileTypes(array('jpg','gif','png'));

		// Label for the upload button in the popup
		$manager->setBrowseButtonText( _t('PubPage.UPLOADONLY', 'Photo (jpg, gif ou png)'));

		// In grid view, what field will appear underneath the icon. If left out, it defaults to the file title.
		$manager->setGridLabelField('Titre');

		// Plural form of the objects being managed. Used on the "Add" button.
		// If left out, this defaults to [MyObjectName]s
		$manager->setPluralTitle(_t('PubPage.UPLOADBUTTON', 'Publications'));

		$f->addFieldToTab("Root.Content.Publications", $manager);

		return $f;
	}
}
class PubPage_Controller extends Page_Controller
{
}

Publication.php :

<?php
class Publication extends DataObject
{
	static $db = array (
		'Titre' => 'Text',
                'Auteur' => 'Text',
                'Pages' => 'Text',
                'Version' => 'Text',
                'Editeur' => 'Text',
		'Description' => 'Text'
	);

	static $has_one = array (
		'Photo' => 'Image',
		'PubPage' => 'PubPage'
	);

	public function getCMSFields_forPopup()
	{
		return new FieldSet(
			new TextField('Titre'),
                        new TextField('Auteur'),
                        new TextField('Pages'),
                        new TextField('Version'),
                        new TextField('Editeur'),
			new TextareaField('Description'),
			new FileIFrameField('Photo')
		);
	}
}
?>

I get this error in the admin cms whenever I create a PubPage!

any help? thanks

The file relationship is "Photo", not "photo".

one thing I didn't quite grasp: I tried has_one 'photo' => 'File' and it worked before, I'm using here has_one 'photo' => 'Image', is this the best option?
