If I have a managed model that I want to restrict which of the DataObjects in the model can be searched for. For example I have a DataObject Student that has_one school so that some of the students have school A and some have school B. I want the ModelAdmin that is managing Students to only be able to search for students that are in School A and not School B. I would think that I could have a hidden field in the SearchForm that has the School A statically defined. I don't know how to accomplish. I want the search to work as if the person searching has put School A in the School search form but I don't actually want the person to see the form or be able to put anything in it.

I hope this makes sense.

On the student dataobject there are a lot of parameters that might help to include. I'm not sure if it'll solve the issue but try adding

static $searchable_fields = array(
'school '

static $defaults = array(
"school " => 'A'

And then I think you'll need to over write the modeladmin search form with $this->fields->removeByName('school ');

I'm not that familiar with SilverStripe, let alone ModelAdmin, so this is guessing form what I've read so far

I just tried to override SearchForm like this:

class MyAdmin extends ModelAdmin{

function SearchForm() {
$form = parent::SearchForm();


But MyAdmin ran as normal. This seems very strange behaviour to me.

shouldn't that be in the overridden ModelAdmin_CollectionController instead of the ModelAdmin class Nicolaas?

I have overridden the form myself, but I am just clueless on how the SearchContext stuff works. I wish it were as simple as the regular site search as that allows you to play with a DataObjectSet to add/remove as you wish... but I have no idea how to get passed the...

$context = singleton($this->modelClass)->getDefaultSearchContext();

...part. is there someone that could shed some light on this please? I have check the documentation and read the source, but the lights haven't come on yet!

probably yes, because it sure did not work ....

But since then I have shifted my attention to DataObject::scaffoldSearchFields and this seems to be very useful.
