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stackoverflow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
