I got so much trouble forming the right query to get my result...
from django.db import models
from django.contrib.auth.models import User
class GeoCatch(models.Model):
user_me = models.ForeignKey(User, null=True, related_name='me')
user_he = models.ForeignKey(User, null=True, related_name='he')
permission_he = models.BooleanField(default=False)
permission_me = models.BooleanField(default=False)
The query I need:
get names in djangos User table of various user_he which have user_me = 1 and have permission_he = True and permission_me= True
This and a couple other querys were not successful...
get_friends = User.objects.values_list('username').filter(geoCatch__user_me=id)/
.filter(permission_he = True).filter(permission_me= True)
Gives me Error:
django.core.exceptions.FieldError: Cannot resolve keyword 'geoCatch' into field.
friends = GeoCatch.objects.filter(user_me=User.objects.get(pk=id)) \
.filter(permission_me=True) \
.filter(permission_he=True).user_he_set.all()
# id is an id of a user object
get_friends = User.objects.values_list('username', flat=True)\
.filter(me__user_me__id=id, me__permission_he = True, me__permission_me= True)
