如何从包含1000个表的数据库中检查db 1表

Question

我有一个包含1000个表的模式,其中许多我不需要,我怎么能只检查db我需要的表？

Answer 1

您可以生成单个表的模型,运行此命令

python manage.py inspectdb TableName > output.py

如果要生成视图模型,这也适用

Answer 2

您可以在python控制台或*.py文件中执行此操作:

from django.core.management.commands.inspectdb import Command
from django.conf import settings
from your_project_dir.settings import DATABASES  #  replace `your_project_dir`

settings.configure()
settings.DATABASES = DATABASES

Command().execute(table_name_filter=lambda table_name: table_name in ('table_what_you_need_1', 'table_what_you_need_2', ), database='default')
