Question

以下是我一直在做的事情，我认为这不是正确的解决方案：

修改我的模型
删除db.sqlite3文件
启动makemigrations，然后migrate

如果我不删除db.sqlite3文件，当我尝试运行makemigrations然后migrate时，我会这样做：

manage.py@pyweb > makemigrations
"C:\Program Files (x86)\JetBrains\PyCharm 4.5.3\bin\runnerw.exe" C:\Python34\python.exe "C:\Program Files (x86)\JetBrains\PyCharm 4.5.3\helpers\pycharm\django_manage.py" makemigrations C:/Users/Olivier/PycharmProjects/pyweb
No changes detected

Process finished with exit code 0
manage.py@pyweb > migrate
"C:\Program Files (x86)\JetBrains\PyCharm 4.5.3\bin\runnerw.exe" C:\Python34\python.exe "C:\Program Files (x86)\JetBrains\PyCharm 4.5.3\helpers\pycharm\django_manage.py" migrate C:/Users/Olivier/PycharmProjects/pyweb
Operations to perform:
  Synchronize unmigrated apps: staticfiles, messages, produits
  Apply all migrations: sessions, auth, contenttypes, admin
Synchronizing apps without migrations:
  Creating tables...
    Running deferred SQL...
  Installing custom SQL...
Running migrations:
  No migrations to apply.

Process finished with exit code 0

为避免删除db文件，我错过了哪一步？

Answer 1

更改模型后，您只需

python manage.py makemigrations your_app

然后使用

进行迁移

python manage.py migrate

这样做你不必删除你的数据库。我希望这有助于你..但是不要忘记在对模型应用更改后运行makemigrations

Pycharm：makemigrations和migrate忽略我的更改
