新建accounts应用

python3 manage.py startapp accounts

创建models.py

  1. # accounts/models.py
  2. from django.db import models
  3. from django.contrib.auth.models import AbstractUser
  6. class MyUser(AbstractUser):
  7.     """自定义用户模型类"""
  9.     mobile = models.CharField(max_length=11, unique=True, verbose_name='手机号')
  11.     # default为函数，如dict, list, tuple等
  12.     dbs = models.JSONField(verbose_name='我的数据库', default=list)
  14.     class Meta:
  15.         db_table = 'my_auth_user'
  16.         verbose_name = 'user'
  17.         verbose_name_plural = 'users'

配置settings.py

  1. # proj/settings.py
  3. # 安装应用
  4. INSTALLED_APPS += ['accounts']
  6. # 覆盖认证模型，注意不是accounts.models.MyUser
  7. AUTH_USER_MODEL = 'accounts.MyUser'

使用MyUser

  1. from accounts.models import MyUser
  3. # 修改用户信息
  4. u = MyUser.objects.get(username='admin')
  5. u.mobile = '13812345678'
  6. u.save()
  8. # 新增用户
  9. new_user = MyUser()
  10. new_user.username = 'demo01'
  11. new_user.set_password('123456')

配置admin

  1. # accounts/admin.py
  3. from django.contrib import admin
  4. from django.contrib.auth.admin import UserAdmin
  5. from django.contrib.auth.models import Group
  7. from .models import MyUser
  8. from .forms import CustomUserCreationForm
  11. ADDITIONAL_USER_FIELDS = (
  12.     (None, {'fields': ('email', 'mobile', 'dbs')}),
  13. )
  16. class CustomUserAdmin(UserAdmin):
  17.     model = MyUser
  19.     add_form = CustomUserCreationForm
  21.     list_display = ['username', 'email', 'mobile', 'dbs']
  23.     add_fieldsets = UserAdmin.add_fieldsets + ADDITIONAL_USER_FIELDS
  26. admin.site.register(MyUser, CustomUserAdmin)
  28. # admin.site.unregister(Group)
  1. # accounts/forms.py
  3. from django.contrib.auth.forms import UserCreationForm, UserChangeForm
  4. from django import forms
  6. from accounts.models import MyUser
  9. class CustomUserCreationForm(UserCreationForm):
  11.     # username = forms.CharField(label='用户名')
  12.     # password1 = forms.CharField(label='密码', widget=forms.PasswordInput)
  13.     # password2 = forms.CharField(label='确认密码', widget=forms.PasswordInput)
  15.     # email = forms.EmailField(label='邮箱地址', required=False)
  17.     # mobile = forms.CharField(label='手机号', required=False)
  18.     # dbs = forms.JSONField(label='数据库', required=False)
  20.     class Meta(UserCreationForm.Meta):
  21.         model = MyUser
  22.         fields = ('username', 'email', 'mobile', 'dbs')
  24.     def save(self, commit=True):
  25.         user = super().save(commit=False)
  26.         user.email = self.cleaned_data["email"]
  27.         user.mobile = self.cleaned_data["mobile"]
  28.         user.dbs = self.cleaned_data["dbs"]
  29.         if commit:
  30.             user.save()
  31.         return user
