Postgresql 如何使用 Django Migrations 重新创建已删除的表

发布于05月22日

有两个模型组和学生，其中只有一个表，学生表被删除.

如何让Django重新创建已删除的表？如果我做makemigrations，它会打印"未检测到任何更改".

在管理页面上，当我点击学生表时，它会抛出一个异常:

relation "students_students" does not exist

推荐答案

In django 1.7 you can try:

1. Delete your migrations folder

2. In the database: DELETE FROM django_migrations WHERE app = 'app_name'.
   You could alternatively just truncate this table.

3. python manage.py makemigrations

4. python manage.py migrate --fake

If you are working in django 1.9.5 this is the 100 % solution for this problem:

1. Delete your migrations folder

2. In the database: DELETE FROM django_migrations WHERE app = 'app_name'.
   You could alternatively just truncate this table.

3. python manage.py makemigrations app_name

4. python manage.py migrate

这对我来说100%有效！
