tastypie get_list filter queryset

class ProjectResource(ModelResource):
  class Meta(object):
    queryset = models.Projects.objects.all()
    resource_name = 'projects'
    list_allowed_methods = ['get', 'post', 'put']
    always_return_data = True
    default_format = 'application/json'
    user = auth.ValidateUser()

  def get_list(self, request, **kwargs):
    user_projects = super(ProjectResource, self).get_list(request, **kwargs)
    result = json.dumps(user_projects.content)
    return http.HttpResponse(result,
                             content_type='application/json', status=200)

This is my tastypie resource. If I found a user from auth.ValidateUser() I need to reply only the associate project from projects table. If not I want to display a error dict saying no project is assigned. I'm not a able to add a filter to get_list. I'm able to do with get_object_list but if I wanted to reply a custom response like error dict ({'error': 'No user mapped.'}) it is throwing error AttributeError: "'dict' object has no attribute 'filter'"

Any help is much appreciated here.

You could do the filtering in get_object_list, then in get_list if the queryset is empty return your dict.

Alternatively, in get_object_list you can do:

from tastypie.exceptions import ImmediateHttpResponse
response = http.HttpResponse(json.dumps({'error': 'No user mapped.'}),
                         content_type='application/json', status=400)
raise ImmediateHttpResponse(response=response)
