Im trying to use Q to make query in django. Database im using for this class is PostgreSQL.
My model is:
class DataSetPG(models.Model):
tower_code = models.CharField(max_length=20, null=False)
time_stamp = models.DateTimeField(default=datetime.now, null=True, blank=True)
value = models.CharField(max_length=200)
class Meta:
ordering = ('tower_code',)
def __str__(self):
return "%s" % self.tower_code
My view is asking for:
DataSetPG.objects.filter(Q(tower_code="something"))
But i got this error:
TypeError: cannot unpack non-iterable Q object
What I'm doing wrong? I tried .get instead of .filter and many many other kinds of stuff, but nothing. Im also using Q for querying in mongo database and works fine.

Putting my comment as an answer:
You can't use the Mongo Q as a Django Q to my understanding. You should instead import like so:
from mongoengine.queryset.visitor import Q as MongoQ
from django.db.models import Q as DjangoQ
With this, instead of Q(tower_code='something') use DjangoQ(tower_code='something'). Wherever you used the Q from mongoengine, replace it with MongoQ.

Yes, that's it. I was already desperate with this and didn't pay attention to the import. Thank you.
