Django-nonrel：重置应用程序的语法 [英] Django-nonrel: Syntax to Reset an App

问题描述

要重置我的应用程序，我运行了这个：

To reset my app, I ran this:

./manage.py reset node

它给我这个错误输出：

WARNING:root:The rdbms API is not available because the MySQLdb library could not be loaded.
Traceback (most recent call last):

在Django-nonrel中重置一个模型？

How do I reset a Model in Django-nonrel?

推荐答案

./manage.py reset node

执行 sqlreset 创建DROPT TABLE和CREATE表给定应用程序的SQL
语句

executes sqlreset to create DROPT TABLE and CREATE TABLE SQL statements for the given app.

https://docs.djangoproject.com/en/1.3/ref/django-admin/#reset-appname-appname

这不适用于App Engine数据存储，因为数据存储是无模式的，因此不需要CREATE / DROP表命令。

This does not work with the App Engine Datastore, because the Datastore is schemaless so there is no need for CREATE/DROP table commands.

如果要从数据存储中删除现有模型，可以使用 App Engine开发控制台删除模型的所有实体（只需确保在访问开发控制台时使用正确的端口）。

If you want to delete existing model from the datastore, you can use the App Engine Development Console to delete all entities of the model (just make sure you use the correct port when accessing the Development Console) .
