Hi,

I am maintaining a large existing site and I am going to add create a new module to contain a new development.

I have a ComplexTable Field maintaining a dataobject called Tip. I have added some page types to the mysite code and tested my functionality. There are no problems there.

When I move the code to a new module in the root, everything looks the same until I come to save my page. I get no error returned but Silverstripe is no longer saving the dataobject relationship.

My page class looks as follows:

class FAQ extends Page {

    static $db = array(
        'RelatedFAQs' => 'HTMLText',
    );

	public static $has_one = array(
		'MyTip' => 'Tip'
	);
	
    function getCMSFields() {
        $fields = parent::getCMSFields();
         
        $tablefield = new HasOneComplexTableField(
            $this,
            'MyTip',
            'Tip',
            array(
                'TipName' => 'Tip Name',
                'TipContent' => 'Tip Content'
            ),
            'getCMSFields_forPopup'
        );
	  		$tablefield->setParentClass('FAQ');
         
        $fields->addFieldToTab( 'Root.Content.Tips', $tablefield );
        $fields->addFieldToTab('Root.Content.Main', new HTMLEditorField('RelatedFAQs'));
         
        return $fields;
    }
	
 
}

My dataobject looks as follows:

class Tip extends DataObject {

	public static $db = array(
		'TipName' => 'Text',
		'TipContent' => 'HTMLText'
	);
   
   function getCMSFields_forPopup() {
       $fields = new FieldSet();
         
       $fields->push( new TextField( 'TipName' ) );
       $fields->push( new HTMLEditorField( 'TipContent' ) );
         
       return $fields;
   }
	public static $has_many = array(
		'FAQs' => 'FAQ'
	);

}

Is this a known issue? Do I need to add anything in to my module config file? It is currently empty.

Thanks in advance!

Has your module got a _config.php file in the root? SS won't parse the directory unless it has. Also you will need to run a ?flush=1 whenever you move classes around.

Hi Willr,

Thanks for getting back. As you know, a gentleman always flushes :-).

I have three installations of this (there is one in UAT etc) and I got this issue in all three after a build, a flush etc.

I have managed to get it working by changing the name of the field holding the relationship between the tip and the faq:

}
   public static $has_many = array(
      'FAQs' => 'FAQ'
   );

}

}
   public static $has_many = array(
      'FAQ' => 'FAQ'
   );

}

I think the relationship was somehow lost after the folder move.

Thanks,

Nick

Hi,

This error has re-occurred after initially working. It makes me think that my HasOneComplexTableField and the dataobject relationship is not defined correctly or something similar.

This time, there has been no movement of the module classes or anything like that. I do not know why it stopped maintaining the relationship between the FAQ page and the Tip dataObject.

When I click save / save and publish, the radio button which I have selected on the HasOneComplexTableField empties at the last moment.

Again, I have done a few rebuilds / changed a few things. The first time I got it back working was when I rolled back all my changes and rebuilt with the original code:

Can anyone see anything incorrect or incomplete here?

class FAQ extends Page {

    static $db = array(
        'RelatedFAQs' => 'HTMLText',
    );

	public static $has_one = array(
		'MyTip' => 'Tip'
	);
	
    function getCMSFields() {
        $fields = parent::getCMSFields();
         
        $tablefield = new HasOneComplexTableField(
            $this,
            'MyTip',
            'Tip',
            array(
                'TipName' => 'Tip Name',
                'TipContent' => 'Tip Content'
            ),
            'getCMSFields_forPopup'
        );
	  		$tablefield->setParentClass('FAQ');
         
        $fields->addFieldToTab( 'Root.Content.Tips', $tablefield );
        $fields->addFieldToTab('Root.Content.Main', new HTMLEditorField('RelatedFAQs'));
         
        return $fields;
    }
	
 
}

class Tip extends DataObject {

	public static $db = array(
		'TipName' => 'Text',
		'TipContent' => 'HTMLText'
	);
   
   function getCMSFields_forPopup() {
       $fields = new FieldSet();
         
       $fields->push( new TextField( 'TipName' ) );
       $fields->push( new HTMLEditorField( 'TipContent' ) );
         
       return $fields;
   }
	public static $has_many = array(
		'FAQ' => 'FAQ'
	);

}
