Show Relating DataObject as link? (Plus speed up record view in model admin)
6 July 2010 at 11:25pm Last edited: 7 October 2010 2:16am
Hi,
I have several relations ($has_one) that are slowing down the speed of browsing the record inside model admin - because the relating table has a lot of rows and it is read ALL rows to create the drop down.
class ExampleObject extends DataObject
{
static $db = array(
'Stuff' => 'Text',
);static $has_one = array(
'RelationToBigTable' => 'BigTable',
);
}So I changed them to be read only text fields (as they are not for changing in the gui anyway!).
class ExampleObject extends DataObject
{
static $db = array(
'Stuff' => 'Text',
);static $has_one = array(
'RelationToBigTable' => 'BigTable',
);function getCMSFields()
{
$fields = parent::getCMSFields();$fields->insertAfter(new ReadonlyField('readonlyfield','RelationToBigTableID',$this->RelationToBigTableID),'Stuff');
$fields->removeByName('RelationToBigTableID');return $fields;
}
}I wonder if there is a way to link them to the other dataobject (also in the same model admin) so that I could turn it into a link and it would jump to editing that record?

Hi,
On the off chance that this is of use to someone... here is the answer to my own question...
function getCMSFields()
{
...
$fields->insertBefore(
new LiteralField('testlit', "<button onClick=\"jQuery('#ModelAdminPanel').fn('loadForm',
'admin/<adminsection*>/<DataObject*>/<id*>/edit',function() {})\"> <buttonlabel*></button>"),'ExtraID');
...
}* fields need completing

yes
also I should point out I now use this rarely as I use this instead now...
$hasOneCTF = new HasOneComplexTableField($this,DATAOBJECTNAME,DATAOBJECTNAME,null,null,'ID='.$this->DATAOBJECTNAMEID);
$hasOneCTF->setPermissions(array('edit','show'));
$hasOneCTF->Markable = false;
$fields->addFieldToTab("Root.DATAOBJECTNAME", $hasOneCTF);and the above link is actually the js called when tapping the edit button on the tab created by teh above code..
