自定义用户认证（继承django的）

1、在app下创建一个自己用户认证文件,文件名随意，记得为.py文件

2、编辑该userauth.py文件

 #!/usr/bin/env python
 #coding:utf-8
 from django.db import models
 from django.contrib.auth.models import (
     BaseUserManager, AbstractBaseUser
 )
 import django

 class UserManager(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,
             #token=token,
             #department=department,
             #tel=tel,
             #memo=memo,

         )

         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,
             #token=token,
             #department=department,
             #tel=tel,
             #memo=memo,
         )
         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,
     )

     is_active = models.BooleanField(default=True)
     is_admin = models.BooleanField(default=False)

     name = models.CharField(u'名字', max_length=32)
     token = models.CharField(u'token', max_length=128,default=None,blank=True,null=True)
     department = models.CharField(u'部门', max_length=32,default=None,blank=True,null=True)

     mobile = models.CharField(u'手机', max_length=32,default=None,blank=True,null=True)

     memo = models.TextField(u'备注', blank=True,null=True,default=None)
     date_joined = models.DateTimeField(blank=True, auto_now_add=True)
     valid_begin_time = models.DateTimeField(default=django.utils.timezone.now)
     valid_end_time = models.DateTimeField(blank=True,null=True)

     USERNAME_FIELD = 'email'  #定义email为用户名
     #REQUIRED_FIELDS = ['name','token','department','tel','mobile','memo']
     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_perms(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

     class Meta:
         verbose_name = u'用户信息'
         verbose_name_plural = u"用户信息"
     def __unicode__(self):
         return self.name

     objects = UserManager()

3、在models中导入该文件中的UserProfile类

4、admin中注册

编辑admin.py文件

 #_*_coding:utf8_*_
 from django.contrib import admin

 # Register your models here.

 from django import forms
 from django.contrib import admin
 from django.contrib.auth.models import Group
 from django.contrib.auth.admin import UserAdmin
 from django.contrib.auth.forms import ReadOnlyPasswordHashField
 import models

 from userauth import UserProfile
 from django.contrib.auth import  forms as auth_form

 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:
         model = UserProfile
         fields = ('email','token')

     def clean_password2(self):
         # 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)
         user.set_password(self.cleaned_data["password1"])
         if commit:
             user.save()
         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(label="Password",
         help_text=("Raw passwords are not stored, so there is no way to see "
                     "this user's password, but you can change the password "
                     "using <a href=\"password/\">this form</a>."))

     class Meta:
         model = UserProfile
         fields = ('email', 'password','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 UserProfileAdmin(UserAdmin):
     # The forms to add and change user instances
     form = UserChangeForm
     add_form = UserCreationForm

     # 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 = ('id','email','is_admin','is_active')
     list_filter = ('is_admin',)
     fieldsets = (
         (None, {'fields': ('email', 'password')}),
         ('Personal info', {'fields': ('department','name','mobile','memo')}),
         ('API TOKEN info', {'fields': ('token',)}),
         ('Permissions', {'fields': ('is_active','is_admin')}),
         ('账户有效期', {'fields': ('valid_begin_time','valid_end_time')}),
     )
     # 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',),
             'fields': ('email',  'password1', 'password2','is_active','is_admin')}
         ),
     )
     search_fields = ('email',)
     ordering = ('email',)
     filter_horizontal = ()

 # Now register the new UserAdmin...
 admin.site.register(models.UserProfile,UserProfileAdmin)
 admin.site.unregister(Group)

 #这里需注意，第51行
"using <a href=\"password/\">this form</a>."))

#这是django1.8的写法，如果>1.8的话需要修改成
"using <a href=\"../password/\">this form</a>."))
否则在admin后台点击修改密码的话会提示404找不到页面

5、在settings告诉django使用我们自己定义的用户认证系统

修改settings，结尾添加

AUTH_USER_MODEL = 'database.UserProfile'

#database为app名称
#UserProfile为我们刚才在userauth.py中创建的类名称

6、同步数据库

可以看到创建了UserProfile表，这样就可以直接使用django的用户认证功能

7、创建超级用户

可以看到提示已经跟django默认的不一样了，以email地址作为用户名

8、此时访问django admin
