How to remove models from django?

Question

In Django how do you remove models that you have synced into the database?

For example in Django tutorial page had this following code

from django.db import models

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice = models.CharField(max_length=200)
    votes = models.IntegerField()

Then I used python manage.py sql polls and python manage.py sql choice to create the tables into the database. But what if I did something wrong and don't want that model any more. What's the syntax to remove it?

Answer 1

If you don't want to delete and re-sync your current database, the best way is to drop the table from your model manually:

$ python manage.py dbshell

> (Inside the DB shell)
> DROP TABLE {app-name}_{model-name};

Answer 2

There is no syntax. Django doesn't removes tables or columns. You have to manually change your database or use a migration tool like South.

If you justing playing around with tutorial the easier way is to delete your sqlite database file and run a sync again.
