C:\Users\Desktop\homeWork\Django_stu_man>python manage.py makemigrations
Migrations for 'app01':
app01\migrations\0001_initial.py
- Create model ClassList
- Create model Course
- Create model CourseRecord
- Create model Customer
- Create model CustomerFollowRecord
- Create model School
- Create model StudyRecord
- Create model UserProfile
- Add field follower to customerfollowrecord
- Add field consultant to customer
- Add field course to customer
- Add field referral_form to customer
- Add field teacher to courserecord
- Add field course to classlist
- Add field teachers to classlist
- Alter unique_together for courserecord (1 constraint(s))
- Alter unique_together for classlist (1 constraint(s)) C:\Users\Desktop\homeWork\Django_stu_man>python manage.py migrate
Operations to perform:
Apply all migrations: admin, app01, auth, contenttypes, sessions
Running migrations:
No migrations to apply.

如上所示,建完表之后,运行python manage.py migrate,总是No migrations to apply,数据库中表也没有建成。

通过查阅资料,大部分建议都是先运行python manage.py makemigrations,再运行python manage.py migrate,然并卵。

最后在*上发现了正解。

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:

DELETE FROM django_migrations WHERE app='your-app-name';

and then do:

python manage.py makemigrations
python manage.py migrate
C:\Users\Desktop\homeWork\Django_stu_man>python manage.py makemigrations
No changes detected C:\Users\Desktop\homeWork\Django_stu_man>python manage.py migrate
Operations to perform:
Apply all migrations: admin, app01, auth, contenttypes, sessions
Running migrations:
Applying app01.0001_initial... OK

binggo!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
