python - 从 Django 在另一个数据库中重新创建表

问题描述

我使用 django 3.1 创建了一个应用程序，我想在另一台计算机上运行代码，我在那台计算机上创建了一个数据库，我想创建表。我正在使用 postgres，我知道我们可以使用 sql 命令手动创建表，但我有很多表。我想知道是否可以使用 django 中的命令来制作它们，因为它们在我的 models.py 文件中。

我已经尝试过py manage.py makemigrations，py manage.py migrate但没有创建表格，而是显示了类似的评论 - 没有检测到任何更改和没有要应用的迁移。

这是我的 settings.py 文件

Django 可以要求您在makemigrations. 因此，只需运行项目根目录中的应用程序在python manage.py makemigrations app1 app2 app3哪里。app1, app2, app3
