GIS: GeoPoint inheritance
12 October 2009 at 1:29pm Last edited: 12 October 2009 1:30pm
hi everybody!
I have a strange behaviour in datamodel and property inheritance, here's what I am trying to do.
class BaseClass extends DataObject {
static $db = array(
'Point' => 'GeoPoint',
'Text' => 'Varchar'
);
}class ChildClass extends BaseClass {
public function getCMSFields(){
print_r($this->Point); // empty
print_r($this->Text); // it's ok, I see this property
}
}It is simplified example of what I am trying to do. This code always return empty object. I have this object entry in db with right Point data, but it always return me object with no coordinates or any data that exist in db. any ideas?

Try Debug::show($this->dbObject('Point')); and see if that returns you the GeoPoint object.

public function getCMSFields() {
Debug::show($this->dbObject('Point'));
}Didn't found better place for it, anyway - it shows nothing...

main problem is not that simple I posted before, but I think it is a cause of this:
[User Error] GeoPoint::setValue() - Bad value '\000\000\000\000\000\000\000���� �T@�����K@'

Looks like a 2.3 specific bug, works fine in SilverStripe trunk - see this unit test: http://open.silverstripe.com/changeset/89142
The 2.3 bug is in DataObject->buildSQL(), where it uses databaseFields() instead of inheritedDatabaseFields(). The logic changed a bit in trunk, and I don't think its feasible to fix something so deep in the core for a late stage release branch. I'd suggest you patch your 2.3 installation for now, or wait for 2.4
