django custom user model


Django Custom user model

Django With one admin function , It means Django By default, there are user management classes . This can also be done from Django See... In the table generated by default . as follows :

mysql> SHOW TABLES;
+----------------------------+
| Tables_in_kylin_ksrcdb |
+----------------------------+
| auth_group |
| auth_group_permissions |
| auth_permission |
| auth_user |
| auth_user_groups |
| auth_user_user_permissions |
| captcha_captchastore |

In general , When we implement the custom user model , Will come from AbstractUser Inherit . Then implement our custom user model . for example :

from django.db import models
from django.contrib.auth.models import AbstractUser # Import AbstractUser
# Create your models here.
class Users(AbstractUser):
...
class Meta:
db_table = 'xxxx' # It's best to have a and Django The default table has different names
verbose_name = ' User management '
verbose_name_plural = verbose_name

such ,model The definition is finished , Now you can generate the migration file , The migration was performed .

python3 manage.py makemigrations
python3 manage.py migrate

You'll find out migrate Report errors 了 . Error is as follows :

django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency users.0001_initial on database 'default'.

Solution

1. Comment out the of the project setting.py In file INSTALLED_APPS In the list 'django.contrib.admin'
2. At the same time, you need to comment out the urls.py Medium urlpatterns In the list path('admin/', admin.site.urls)
3. perform migrate, I can't tell you wrong .
4. Just change the notes back .
5. perform runserver, Found that the project can run successfully 

The above is the possible problems and solutions of user-defined model .
