自定义一个用户认证
详细参考官方文档：
https://docs.djangoproject.com/en/1.9/topics/auth/customizing/#django.contrib.auth.models.PermissionsMixin.has_perms
一、创建用户的表
UserProfile()：存放用户信息的表
UserProfileManager(): 用户创建用户的类方法
1、生成一个单独的Moel文件专门用来存放用户表
#!/usr/bin/env python # _*_coding:utf-8_*_ from django.db import models from django.contrib.auth.models import ( BaseUserManager, AbstractBaseUser ) class UserProfileManager(BaseUserManager): def create_user(self, email, name, password=None): """ Creates and saves a User with the given email, date of birth and password. """ if not email: raise ValueError('Users must have an email address') user = self.model( email=self.normalize_email(email), name=name, ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, name, password): """ Creates and saves a superuser with the given email, date of birth and password. """ user = self.create_user(email, password=password, name=name ) user.is_admin = True user.save(using=self._db) return user class UserProfile(AbstractBaseUser): email = models.EmailField( verbose_name='email address', max_length=255, unique=True, ) name = models.CharField(max_length=64) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) class Meta: verbose_name = '用户表' verbose_name_plural = '账户表' objects = UserProfileManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['name'] def get_full_name(self): # The user is identified by their email address return self.email def get_short_name(self): # The user is identified by their email address return self.email def __str__(self): # __unicode__ on Python 2 return self.email def has_perm(self, perm, obj=None): "Does the user have a specific permission?" # Simplest possible answer: Yes, always return True def has_module_perms(self, app_label): "Does the user have permissions to view the app `app_label`?" # Simplest possible answer: Yes, always return True @property def is_staff(self): "Is the user a member of staff?" # Simplest possible answer: All admins are staff return self.is_admin
2、在models里面添加自定义的用户表
# _*_coding:utf-8_*_ from django.db import models from collect_app.user_models import UserProfile
3、在settings里面指定自定义表的位置，django会默认去models文件里去找相应的表 （app名+表名）
AUTH_USER_MODEL = 'collect_app.UserProfile'
此时，在用Manage.py创建用户时，就是自定义的创建过程
二、在Django Admin里面显示自定义的用户表
要把自定义的用户表在Django admin里面显示，需要稍加修改并注册到admin里
1、创建user_admin.py用来重写admin。
2、创建用户显示的UserAdmin类方法，并将其中的字段与自定义用户表的字段对应
3、创建更改用户和创建用户的类方法
#!/usr/bin/env python # _*_coding:utf-8_*_ from django import forms from django.contrib import admin from django.contrib.auth.models import Group from django.contrib.auth.admin import UserAdmin as BaseUserAdmin from django.contrib.auth.forms import ReadOnlyPasswordHashField from collect_app.models import UserProfile # 导入自定义的用户表 class UserCreationForm(forms.ModelForm): """A form for creating new users. Includes all the required fields, plus a repeated password.""" password1 = forms.CharField(label='Password', widget=forms.PasswordInput) password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput) class Meta: # 将其关联到UserProfile表 model = UserProfile fields = ('email', 'name') def clean_password2(self): # 判断两次密码输入 # Check that the two password entries match password1 = self.cleaned_data.get("password1") password2 = self.cleaned_data.get("password2") if password1 and password2 and password1 != password2: raise forms.ValidationError("Passwords don't match") return password2 def save(self, commit=True): # Save the provided password in hashed format user = super(UserCreationForm, self).save(commit=False) # 继承父类的save方法 并重写 user.set_password(self.cleaned_data["password1"]) if commit: user.save() # 保存创建的密码 return user class UserChangeForm(forms.ModelForm): """A form for updating users. Includes all the fields on the user, but replaces the password field with admin's password hash display field. """ password = ReadOnlyPasswordHashField() class Meta: model = UserProfile # 将其关联到UserProfile表 fields = ('email', 'password', 'name', 'is_active', 'is_admin') def clean_password(self): # Regardless of what the user provides, return the initial value. # This is done here, rather than on the field, because the # field does not have access to the initial value return self.initial["password"] class UserAdmin(BaseUserAdmin): # The forms to add and change user instances form = UserChangeForm # 修改用户信息 add_form = UserCreationForm # 创建用户信息 # The fields to be used in displaying the User model. # These override the definitions on the base UserAdmin # that reference specific fields on auth.User. list_display = ('email', 'name', 'is_admin') # 显示的字段 list_filter = ('is_admin',) fieldsets = ( # 分行显示 (None, {'fields': ('email', 'password')}), ('Personal info', {'fields': ('name',)}), ('Permissions', {'fields': ('is_admin',)}), ) # add_fieldsets is not a standard ModelAdmin attribute. UserAdmin # overrides get_fieldsets to use this attribute when creating a user. add_fieldsets = ( (None, { 'classes': ('wide',), # 显示样式 'fields': ('email', 'name', 'password1', 'password2')} # 创建用户时显示的字段 ), ) search_fields = ('email',) # 按email搜索 ordering = ('email',) filter_horizontal = () # Now register the new UserAdmin... # admin.site.register(UserProfile, UserAdmin) # ... and, since we're not using Django's built-in permissions, # unregister the Group model from admin. admin.site.unregister(Group) # 不显示Group
4、将自定义UserAdmin的方法注册到admin里面
from user_admin import UserAdmin admin.site.register(models.UserProfile, UserAdmin) # 将自定义的Admin注册到自定义的用户表中。
至此，再次登录django admin时，用户的信息就是我们自定义的信息。包括修改和创建用户时，都是我们自定义的内容。
