pass a variable from a different table than SiteTree DB to JSON
5 June 2010 at 4:08am
Hi all,
We did a nice implementation of flash with the Silverstripe backend. We're working on it, have a look:
http://krayersm.sites.hostmax.ch/projekte/Everything works well, except that we can't pass on variables from other tables, just default fields from the SiteTree like $Title, $MenuTitle, $URLSegment...
The JSON output you can see from: http://krayersm.sites.hostmax.ch/projekt1/jsonausgabe
The variable 'Anzahl' just shows: Anzahl":null," which is not the data existing in this field.
Does anybody know why this variable is not being sent with JSON. We even can't access the $Ausgabe in a SS-file.We'd be really glad to get a feedback.
yesmate!

You have the following code
'Anzahl' => $this->Anzahl,
'DeltaX' => $this->DeltaX,
'DeltaY' => $this->DeltaY,$this->Field would look for the database field on ProjektPage or Page.php. Those fields aren't on ProjektPage so $this-> won't work. Your using a ComplexTableField to manage the objects - did you want to attach multiple Projekteintrag to the ProjektPage or just 1? If its just one then you need a relationship to map the object to the page
static $has_one = array('Projekteintrag' => 'Projektangaben');
Then your ComplexTableField needs to be changed to a HasOneComplexTableField and that code I posted first would be changed to look like
'Anzahl' => $this->Projekteintrag()->Anzahl,
'DeltaX' => $this->Projekteintrag()->DeltaX,
'DeltaY' => $this->Projekteintrag()->DeltaY, -

Hi Willr,
Thanks a lot for your reply. I changed the files according to your suggestion. Just the 'HasOneComplexTableField' I couldn't use otherwise the fields woudn't show in the backend after filling in the form... so I left it to ComplexTableField.
I had no errors, just the
http://krayersm.sites.hostmax.ch/projekt1/jsonausgabe
still shows:"Anzahl":null,"DeltaX":null,"DeltaY":null,
...where it should show the value from the DB.
Could you imagine why?I attached the two changed files (attention: all the 'projektangaben' I changed to 'projektangabe').
Thanks
