AttributeError: 'QuerySet' object has no attribute 'model'

The code is simple:

Models.py

from future import unicode_literals

from mongoengine import *

connect('test',alias='default')

class user(Document):

email = StringField(required=True)  

first_name = StringField(max_length=50) 
last_name = StringField(max_length=50) 

class Comment (EmbeddedDocument): content=StringField() name=StringField(max_length=120)

class Post(Document): title=StringField(max_length=120, required=True) author = ReferenceField(user,reverse_delete_rule=CASCADE) tags=ListField(StringField(max_length=30)) comments=ListField(EmbeddedDocumentField(Comment)) meta={'allow_inheritance':True}

class TextPost(Post): content = StringField()

class ImagePost(Post): image_path=StringField()

class LinkPost(Post): link_url=StringField()

BlogModelResources.py

from tastypie.resources import ModelResource
from blog.models import user

class UserResource(ModelResource):
class Meta:
queryset = user.objects.all()

Django (1.10.1) django-filter (1.0.1) django-rest-framework-mongoengine (3.3.1) django-tastypie (0.13.3) django-tastypie-mongoengine (0.4.6) djangorestframework (3.5.3) pymongo (3.4.0)

I always got the error message:
