First my django model was like this:

class List(Document):
    owner = ReferenceField('User')
    name = StringField()
    users = ListField(ReferenceField('User'))
    created_at = DateTimeField(default=datetime.datetime.now)

After I added a new filed is_cancelled and now it is like that:

class List(Document):
    owner = ReferenceField('User')
    name = StringField()
    users = ListField(ReferenceField('User'))
    created_at = DateTimeField(default=datetime.datetime.now)
    is_cancelled = BooleanField(default = False)

I use mongoengine for django mongodb ORM. But now when i want to make a filter query:

List.objects.filter(is_cancelled=False)
returns []

I make all is_cancelled fields to False with django object:

for x in List.objects.all():
    x.is_cancelled = False
    x.save()

But I’m still getting an empty list for the query above.
I’m looking a django objects’ is_cancelled filed and I see is_cancelled = False

l = List.objects.all()[0]
l.is_cancelled

False

But when I look from mongodb shell. There is no filed as is_cancelled.

db.list.find()
{ "_cls" : "List", "_id" : ObjectId("4e8451598ebfa80228000000"), "_types" : [ "List" ],     
"created_at" : ISODate("2011-09-29T16:24:28.781Z"), "name" : "listname", "users" : [          
{
            "$ref" : "user",
            "$id" : ObjectId("4e79caf78ebfa80c00000001")
    },      {
            "$ref" : "user",
            "$id" : ObjectId("4e79e4df8ebfa80b64000001")
    },      {
            "$ref" : "user",
            "$id" : ObjectId("4e7aeb898ebfa80b64000001")
    },      {
            "$ref" : "user",
            "$id" : ObjectId("4e79ce028ebfa80c00000004")
    } ] }

How can I fix this query
