如何从SQLite3在DJango中删除表？ [英] How do I drop a table from SQLite3 in DJango?

问题描述

我做了一个模型，并运行python manage.py syncdb。我认为在db中创建了一个表。然后我意识到我做了一个不正确的列，所以我改变它，并执行相同的命令，认为它会删除旧的表，并添加一个新的。

I made a model, and ran python manage.py syncdb. I think that created a table in the db. Then I realized that I had made a column incorrectly, so I changed it, and ran the same command, thinking that it would drop the old table, and add a new one.

然后我去了python manage.py shell，并试图运行.objects.all（），它失败，说列不存在。

Then I went to python manage.py shell, and tried to run .objects.all(), and it failed, saying that column doesn't exist.

我想清除旧的表，然后再次运行syncdb，但我不知道该怎么做。

I want to clear out the old table, and then run syncdb again, but I can't figure out how to do that.

推荐答案

p>另一种使用Django 1.4或更低版本的简单方法是

Another simple way to do this while using Django 1.4 or below, would be

python manage.py reset app_name

会删除并重新创建此应用程序的模型所使用的表。

which drops and re-creates the tables used by the models of this app.

这已在Django 1.3中弃用，不再可从Django 1.5中使用

This was deprecated in Django 1.3 and is no longer available from Django 1.5
