Pycharm: makemigrations 和 migrate 忽略我的更改

Question

这是我一直在做的事情，我想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，我有这个：

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

我错过了什么步骤来避免删除数据库文件？

Answer 1

更改模型后你就可以了

python manage.py makemigrations your_app

然后用

迁移它

python manage.py migrate

这样做你不必删除你的数据库。我希望这对你有帮助.. 但不要忘记运行在对模型应用更改后进行迁移
