Hi, So I just setup celery and rabbitmq, created my user, setup the vhost, mapped the user to the vhost, and ran the celery daemon succesfully (or so I assume) (queuetest)corky@corky-server:~/projects/queuetest$ ./manage.py celeryd celery@corky-server v0.9.5 is starting. Configuration -> . broker -> amqp://celery@localhost:5672/ . qu...
I think I've read somewhere that Django's ORM lazily loads objects. Let's say I want to update a large set of objects (say 500,000) in a batch-update operation. Would it be possible to simply iterate over a very large QuerySet, loading, updating and saving objects as I go? Similarly if I wanted to allow a paginated view of all of these ...
I have a queryset with a few million records. I need to update a Boolean Value, fundamentally toggle it, so that in the database table the values are reset. What's the fastest way to do that? I tried traversing the queryset and updating and saving each record, that obviously takes ages? We need to do this very fast, any suggestions? ...
Hi, so... I have a huge list ranked by various values (eg. scores) So I grab the list ordered by these values: players = Player.objects.order_by('-score', '-karma') I would like to: Grab a player and get the neighbouring players P1 score:123 P2 score:122 YOU! score:110 P3 score:90 P2 score:89 Grab the...
I have a field in my module that is used to hold the status of the object. So far I have used: ORDER_STATUS = ((0, 'Started'), (1, 'Done'), (2, 'Error')) status = models.SmallIntegerField(choices=ORDER_STATUS) Its easy to convert one way: def status_str(self): return ORDER_STATUS[self.status][1] The problem is when updating. I find...
Let's say that I have a model: class Ticket(models.Model): client = models.ForeignKey(Client) color = models.CharField(max_length=255) def clean(self): self.color = self.client.favorite_color When I run this on the latest Django (head of the SVN from 15 minutes ago), if I hit save without selecting a client, I get...
I'm trying to follow the code from http://docs.djangoproject.com/en/1.1/topics/auth/ regarding user logins. def my_view(request): username = request.POST['username'] password = request.POST['password'] user = authenticate(username=username, password=password) if user is not None: if user.is_active: ...
I'm running into this error when I attempt to syncdb: auth.user: The model User has two manually-defined m2m relations through the model FavoriteQuestion, which is not permitted. Please consider using an extra field on your intermediary model instead. I'm really don't understand what it means because I only see 1 model-to-model relation...

Ideally I'd like to be able to do something like: id_of_new_row = cursor.lastrowid() in which I get the id of the newly created or modified row. But this isn't available through psycopg2. Alternatively, I've tried this: id_of_new_row = cursor.execute('INSERT INTO this_table (value1, value2, value3) VALUES (%s, %s, %s) RETURNING id'...
I have a custom property on my Django model that returns the full name of a Person: class Person(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) def _get_full_name(self): return "%s %s" % (self.first_name, self.last_name) full_name = property(_get_full_name) When I create ...
All the time in Django I see DoesNotExist being raised like in db.models.fields.related.py. Not ObjectDoesNotExist which is defined in django.core.exceptions, but just DoesNotExist. Where is this exception class defined, or am I not fully understanding exceptions? I've checked that it's not in exceptions (at least not that I know of). I'...
I have a Python web application (Django, specifically). I'm reading in some data from a Trac database (where the descriptions use wiki formatting) and displaying it as HTML. I considered the markdown module, but realised that Trac wiki formatting and markdown are really quite different. Is there a module for Django, or a Python package t...
Hi. I'm running production server with 12 projects written in PHP and Python (Django framework). The problem is that every time i commit something to svn i have to ssh to server and do svn update manually. I've made a simple shell script for this, but it's definitenly not an option. I thought about capistrano+webistrano, but for this i'...
Hi, I'm a student and the lab staff has set up permissions that won't students install software on the machines (or to our profiles).

But when I try to use django-a...

Is there a way to count my queries during a manage.py shell session? It would be helpful as a means to inspect some of the ORM behavior between queries. Additionally, it would be nice to pull the queries themselves, and I guess their execution times while I'm at it. i.e. >>>from myapp.models import User >>>User.objects.filter(...
