Debugtoolbar misses query and double inheritance=dobule save and object doesn't save

        return self.__call__(pk__gt=date_int) if gt else self.__call__(pk__lt=date_int)

class PP(db.Document):
    theid= SequenceField(primary_key=True)

class Parent(object):
    updated = DateTimeField(db_field="2")
    created = IntField(primary_key=True)

    meta = {'cascade': False, 'allow_inheritance': False, 'queryset_class': AwesomerQuerySet}

    @classmethod
    def pre_save(cls, sender, document, **kwargs):
        document.gen_pk()
        print "pre_save"

    def gen_pk(self):
        self.created = str(self.project.pk)+str(int(time.mktime(datetime.datetime.utcnow().timetuple()) * 100 + random.randrange(99)))

class One(Parent,db.Document):
    related_videos = ListField(ReferenceField('Video',dbref=False),db_field="r")
    ssss = StringField()
    title = StringField(db_field="t")
    meta = {'cascade': False, 'allow_inheritance': False, 'queryset_class': AwesomerQuerySet}

signals.pre_save.connect(One.pre_save, sender=One)

@app.route('/test/')
def domain_testing():
    pp = PP()
    pp.save()
    one = One(project=pp)
    one.save()

    return render_template("empty.html")

The problems:

Save is triggered twice on the One class. There should be 3 queries in the toolbar: 1.PP created 2.One create 3.One updated. Only 3 is in the toolbar. PP object is not saved in the db. Ignore the queryset.

Please change the class in related_videos to something else. That listfield is so you can see in the debugtoolbar that the second save is removing the empty list because empty queries are not showed in the debugtoolbar.

Would you be willing to provide a testcase + pull request?
