问题描述
我一直在家里摆弄 Django 和 Django ORM，我不得不说，我觉得它是最好的易用性之一.
I've been messing around with Django and the Django ORM at home, and I've got to say, I feel it is one of the best out there in terms of ease of use.
但是，我想知道是否可以反向"使用它.
However, I was wondering if it was possible to use it in "reverse".
基本上我想做的是从现有的数据库模式(来自一个不使用 django 并且很旧的项目)生成 Django 模型.
Basically what I would like to do is generate Django models from an existing database schema (from a project that doesn't use django and is pretty old).
这可能吗?
更新:有问题的数据库是 Oracle
Update: the database in question is Oracle
推荐答案
是的，使用 inspectdb 命令:
- http://docs.djangoproject.com/en/dev/ref/django-admin/#inspectdb
检查数据库
内省 DATABASE_NAME 设置指向的数据库中的数据库表，并将 Django 模型模块(models.py 文件)输出到标准输出.
Introspects the database tables in the database pointed-to by the DATABASE_NAME setting and outputs a Django model module (a models.py file) to standard output.
如果您有一个要使用 Django 的旧数据库，请使用此选项.该脚本将检查数据库并为其中的每个表创建一个模型.
Use this if you have a legacy database with which you'd like to use Django. The script will inspect the database and create a model for each table within it.
如您所料，创建的模型将具有表中每个字段的属性.请注意，inspectdb 在其字段名输出中有一些特殊情况:
As you might expect, the created models will have an attribute for every field in the table. Note that inspectdb has a few special cases in its field-name output:
