Recently I have been trying to learn web development in Django and i am very happy about it... But, one thing is really annoying -especially when you get the idea about 'simplicity' philosophy behind django. It is that updating a table in django is really far away from simplicity as i just experienced. For example, just like the real ...
Hi, I'm going to post some incomplete code to make the example simple. I'm running a recursive function to compute some metrics on a hierarchical structure. class Category(models.Model): parent = models.ForeignKey('self', null=True, blank=True, related_name='children', default=1) def compute_metrics(self, shop_object, metric_queryse...
We've got some really strange extraneous DB hits happening in our project. Is there any way to monitor where the requests are coming from, possibly by line number? The SQL printing middleware helps, but we've looked everywhere those kinds of requests might be generated and can't find the source. If the above isn't possible, any pointers...

Hi at all. I have a project with 2 applications ( books and reader ). Books application has a table with 4 milions of rows with this fields: book_title = models.CharField(max_length=40) book_description = models.CharField(max_length=400) To avoid to query the database with 4 milions of rows, I am thinking to divide it by subject ( ...
So far Django has good integration with several RDBMS. NoSQL, schema-less and document-oriented DBMS are picking up. What's the status of integration those on-trend and fashionable DBMSes with Django? Are there any production-ready or at least ready-to-use libraries for Django? So far I have these at hand: http://github.com/lethain/co...
If you've got a database setup in Django, how can you have the TestRunner use the 'live' database (per the DATABASE_* settings in settings.py) instead of running them on the ephemeral test database. For example, I'd like to run the following test on the live database that's specified in settings.py: import unittest from example import...
I know this exists django-admin.py inspectdb > models.py However, is there an easy way to limit it? Without manually deleting what I don't want. I'm connecting to a database that has over one hundred tables, but I only want models of about 4 or 5. Is there an easy way to generate models from a few given tables? They are quite big ta...
I'm interested in running Django on an async framework like Concurrence or gevent. Both frameworks come with its own async MySQL driver. Problem is Django only officially supports MySQLdb. What do I need to do to make Django work with the MySQL drivers that come with gevent or Concurrence? Is there a step-by-step guide somewhere that ...
Has anyone made Django work with myconnpy? I've checked out http://github.com/rtyler/connector-django-mysql but the author said it's very outdated and not supported. If you've managed to make Django work with myconnpy, please share your experience. Thanks. ...

I have some django models for my extended users profile. Problem is that this code does not create tables when syncdb is used (simply nothing happens. No validation errors). Why is that happening? (Also those models give import error elsewhere) : #!/usr/bin/env python # encoding: utf-8 from django.db import models from django.contrib.au...
I am working on one project with django 1.2. I have 2 databases : - First, for users, user's profile, session ... - Second is to store data from my specifics models like post of blog, pictures, files ...

Hi, anyone know if there's a django database debugging app which supports Django's multi-db API? I used to use django-debug-toolbar but it doesn't support multiple databases and the corresponding ticket is now open for 3 months. Are there any alternatives worth looking at? ...

Is there a way to specify that a model (or app, even) should only ever use one particular database? I am working with a legacy database that I don't want to change. I have two databases - the 'default' is an sqlite one that could be used for admin etc, and the legacy one. I used inspectdb to create a model for (part of) the legacy datab...
Hi, I've hit a bit of a wall when trying to add data to a UserProfile model created to hold user info beyond what is catered for in django's built in Auth component. My question is how do I get an instance of the user just registered in order to create the the UserProfile? I thought it would be something like below: # Registration for...
