No migrations to apply
Django keeps track of all the applied migrations in django_migrations table. So just delete all the rows in the django_migrations table that are related to you app like:
python manage.py makemigrations
python manage.py migrate
Django. No changes detected when "makemigrations"
在修改了models.py后,有些用户会喜欢用python manage.py makemigrations生成对应的py代码。
但有时执行python manage.py makemigrations命令,会提示"No changes detected." 可能有用的解决方式如下:
直接使用python manage.py migrate.
可能会先生成对应数据库的py代码,再自动执行这段代码,创建数据库表格 (我没有仔细去读文档 不清楚这条命令的逻辑)来自:https://docs.djangoproject.com/en/1.8/topics/migrations/
先python manage.py makemigrations --empty yourappname
生成一个空的initial.py
再python manage.py makemigrations
生成原先的model对应的migration file
