I am trying to construct a simple or
query using MongoEngine
and the django.db.models.Q
class.
My code (run from ./manage.py shell
) is:
from db.models import User
from django.db.models import Q
User.objects.filter(Q(username='foo') | Q(email='bar'))
My models.py
is just
from mongoengine import *
class User(Document):
username = StringField()
email = StringField()
I have tried several different versions, and always get the following error:
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "venv/lib/python2.7/site-packages/mongoengine/queryset/base.py", line 193, in filter
return self.__call__(*q_objs, **query)
File "venv/lib/python2.7/site-packages/mongoengine/queryset/base.py", line 109, in __call__
raise InvalidQueryError(msg)
InvalidQueryError: Not a query object: (OR: ('username', 'foo'), ('email', 'bar')). Did you intend to use key=value?
I'm using Python 2.7.6 with the following packages:
dj-database-url==0.3.0
dj-static==0.0.6
Django==1.8
django-toolbelt==0.0.1
gunicorn==19.3.0
mongoengine==0.9.0
psycopg2==2.6
pymongo==2.8
static3==0.5.1
I am new to Python and Django, but this seems fairly simple. What am I doing wrong?
It turns out that I was importing the wrong Q
class. For MongoEngine
it should be:
from mongoengine.queryset.visitor import Q
