How to return Random items from a Mongodb Resource

[Anuj Chauhan]

Hi Friends,

I need to return random items from a tastypie resource which is a resources.MongoEngineResource.

I have already tried using MyClass.objects.all().order_by('?'), but it simply keep returning the same rows always. Following is the code of my resource.

class MViewSubResponseRandomResource(resources.MongoEngineResource):

    class Meta:

        queryset = SubResponse.objects.all().filter(asset_type='Photo').order_by('?')

        resource_name = 'mview/random'

        allowed_methods = ['get']

        authentication = SillyAuthentication()

        authorization = SillyAuthorization()

    def dehydrate(self, bundle):

        resource_uri = self.get_resource_uri(bundle)

        bundle.data = {}

        bundle.data['id']=bundle.obj.id

        bundle.data['file_url']=bundle.obj.file_url

        bundle.data['action_type']=bundle.obj.action_type

        bundle.data['asset_type']=bundle.obj.asset_type

        bundle.data['resource_uri']=resource_uri

        bundle.data['end_date']=bundle.obj.end_date

        return bundle

    

    def get_object_list(self, request):

        workgroup_id=request.REQUEST['wid']

        superset_limit=1000

        subresponses = SubResponse.objects.all().filter(asset_type='Photo', rejected=False, work_group_id=workgroup_id).order_by('?')[:superset_limit]

        return subresponses

Regards,

Anuj

Hello,

You should use the Python's built-in random module. See random.sample()
