django.db.migrations.exceptions.InconsistentMigrationHistory [英] django.db.migrations.exceptions.InconsistentMigrationHistory
问题描述
当我在Django项目上运行 python manage.py migration
时,出现以下错误:
When I run python manage.py migrate
on my Django project, I get the following error:
Traceback (most recent call last):
File "manage.py", line 22, in <module>
execute_from_command_line(sys.argv)
File "/home/hari/project/env/local/lib/python2.7/site- packages/django/core/management/__init__.py", line 363, in execute_from_command_line

connection.alias,
django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency account.0001_initial on database 'default'.
我的用户模型如下:
class User(AbstractUser):
place = models.CharField(max_length=64, null=True, blank=True)
address = models.CharField(max_length=128, null=True, blank=True)
如何解决此问题?
推荐答案
您数据库中的django_migrations表是导致不一致的原因,仅从本地路径删除所有迁移将不起作用。
Your django_migrations table in your database is the cause of inconsistency and deleting all the migrations just from local path won't work.
您必须从数据库中截断django_migrations表,然后尝试再次应用迁移。它应该可以工作,但是如果不能运行,请再次运行makemigrations然后再进行迁移。
You have to truncate the django_migrations table from your database and then try applying the migrations again. It should work but if it does not then run makemigrations again and then migrate.
注意:请不要忘记备份数据。
Note: don't forget to take a backup of your data.
