How can I check if an user is superuser in django
I'm listing registered users on a ListView page and I'm trying to show if user is superuser or not. My main user is created with "manage.py createsuperuser" command and I'm sure it is a superuser beacuse I've checked from admin panel too. When I try to print if it is superuser or not my code always shows a "False" output. Here are my codes: views.py @method_decorator(staff_member_required, name='dispatch') class Uyeler(ListView): model = User paginate_by = 40 ordering = ['-pk'] template_name = "panel/uyeler.html" and in template file: {% for obj in object_list %} {% if obj.is_superuser %}SuperUser {% else %} Not SuperUser {{ obj.is_superuser }} {%endif%} {% endfor % And my html output is "Not SuperUser False" for all users including my superuser account. Any ideas? -

Bulk create with multi-table inheritance models
I'm using multi-table inheritance models. from django.db import models class Place(models.Model): name = models.CharField(max_length=50) address = models.CharField(max_length=80) class Restaurant(Place): serves_hot_dogs = models.BooleanField(default=False) serves_pizza = models.BooleanField(default=False) class Cinema(Place): sells_tickets = models.BooleanField(default=False) sells_popcorn = models.BooleanField(default=False) class Coffee(Place): sells_tea = models.BooleanField(default=False) I have a view that creates several different models: items = [ Restaurant(...), Restaurant(...), Restaurant(...), Cinema(...), Cinema(...), Coffee(...), Coffee(...), # + 1.000 other items ] for item in items: item.save() Obviously, this is really inefficient since it creates a lot of queries. Unfortunately, Django doesn't provide a bulk-create method for multi-table inheritance yet (there is an open pull request for it). What is the best way to optimize this code? Do I have to write a raw SQL query or is there another way? -

Working with composite primary key and foreign keys in django project with legacy database
In this question, e4c5 suggests updating tables in the legacy database with a single primary key to work with Django. However, every table referencing the updated table will be using the composite primary key as reference and will therefore not work in Django. Is there a way to either update the tables so they would use the new primary key, or a workaround for this? -
