Hi Everyone.

I am having a peculiar error that I cant seem to locate the issue. I am simply creating a DOM to display news articles. I have successfully created the page and added articles within the CMS. The problem is when I click on the edit button for one of the items, i get an error message about a query issue.

I tried to just start all the way in the begining and use a working example from uncle Cheese's Testimonial code. Still no progress.

I am pasting my code below, along with the error. Maybe I am missing something small, or this is something larger?

Here is the NewsArticlePage code

<?php
class DPSNewsArticlePage extends Page
{
	static $has_many = array (
		'DPSNewsArticles' => 'DPSNewsArticle'
	);
	
	public function getCMSFields()
	{
		$f = parent::getCMSFields();
		$manager = new DataObjectManager(
			$this, // Controller
			'DPSNewsArticles', // Source name
			'DPSNewsArticle', // Source class
			array('Date' => 'Date', 'Author' => 'Author', 'Quote' => 'Quote'), // Headings
			'getCMSFields_forPopup' // Detail fields function or FieldSet
			// Filter clause
			// Sort clause
			// Join clause
		);
		
		
		$f->addFieldToTab("Root.Content.Articles", $manager);
		
		return $f;
	}

}
class DPSNewsArticlePage_Controller extends Page_Controller
{
}
?>

<?php
class DPSNewsArticle extends DataObject
{
	static $db = array (
		'Date' => 'Date',
		'Author' => 'Text',
		'Quote' => 'Text'
	);
	
	static $has_one = array (
		'DPSNewsArticlePage' => 'DPSNewsArticle'
	);
	
	public function getCMSFields_forPopup()
	{
		return new FieldSet(
			new DatePickerField('Date'),
			new TextField('Author'),
			new TextareaField('Quote')
		);
	}
}
?>

Are you sure this is what you want??

static $has_one = array (
'DPSNewsArticlePage' => 'DPSNewsArticle'
);

Look at that closely.

Doh! Yes, I see it now. I changed to below and it works. Thanks UC. I appreciate you taking time to point this out. I actually like that you turned it back on me to see it. Good way to learn form my mistake.

static $has_one = array (
'DPSNewsArticlePage' => 'DPSNewsArticlePage'
);
