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
