标签：email password create import 第一时间
环境
Python 3.5.1
django 1.9.1
今天用django写web平台，第一时间想到django自带的认证，连session都提供好了，既然有轮子了，我们就不需要自己造了。
需求
注册登录都有现成的代码，主要是自带的User字段只有（email,username,password）,所以需要扩展User,来增加自己需要的字段
代码如下：
model.py
#coding:utf8 from django.db import models from django.contrib.auth.models import AbstractUser from django.utils.encoding import python_2_unicode_compatible # Create your models here. @python_2_unicode_compatible """是django内置的兼容python2和python3的unicode语法的一个装饰器 只是针对 __str__ 方法而用的，__str__方法是为了后台管理(admin)和django shell的显示，Meta类也是为后台显示服务的 """ class MyUser(AbstractUser): qq = models.CharField(u‘qq号‘, max_length=16) weChat =models.CharField(u‘微信账号‘, max_length=100) mobile =models.CharField(u‘手机号‘, primary_key=True, max_length=11) identicard =models.BooleanField(u‘身份证认证‘, default=False) #默认是0，未认证， 1：身份证认证， 2：视频认证 refuserid = models.CharField(u‘推荐人ID‘, max_length=20) Level = models.CharField(u‘用户等级‘, default=‘0‘, max_length=2) #默认是0，用户等级0-9 vevideo = models.BooleanField(u‘视频认证‘, default=False) #默认是0，未认证。 1：已认证 Type =models.CharField(u‘用户类型‘, default=‘0‘, max_length=1) #默认是0，未认证， 1：刷手 2：商家 def __str__(self): return self.username
settings.py
AUTH_USER_MODEL = ‘appname.MyUser‘ AUTHENTICATION_BACKENDS = (‘django.contrib.auth.backends.ModelBackend‘,)
踩过的坑：
1、扩展user表后，要在settings.py 添加
AUTH_USER_MODEL = ‘appname.扩展user的class name‘
2、认证后台要在settings添加，尤其记得加逗号，否则报错
认证后台不加的报错
Django-AttributeError ‘User‘ object has no attribute ‘backend‘
没加逗号的报错
ImportError: a doesn‘t look like a module path
form.py
#coding:utf-8
from django import forms
#注册表单
class RegisterForm(forms.Form):
username = forms.CharField(label=‘用户名‘,max_length=100)
password = forms.CharField(label=‘密码‘,widget=forms.PasswordInput())
password2 = forms.CharField(label=‘确认密码‘,widget=forms.PasswordInput())
mobile = forms.CharField(label=‘手机号‘, max_length=11)
email = forms.EmailField()
qq = forms.CharField(label=‘QQ号‘, max_length=16)
type = forms.ChoiceField(label=‘注册类型‘, choices=((‘buyer‘,‘买家‘),(‘saler‘,‘商家‘)))
def clean(self):
if not self.is_valid():
raise forms.ValidationError(‘所有项都为必填项‘)
elif self.cleaned_data[‘password2‘] != self.cleaned_data[‘password‘]:
raise forms.ValidationError(‘两次输入密码不一致‘)
else:
cleaned_data = super(RegisterForm, self).clean()
return cleaned_data
#登陆表单
class LoginForm(forms.Form):
username = forms.CharField(label=‘用户名‘,widget=forms.TextInput(attrs={"placeholder": "用户名", "required": "required",}),
max_length=50, error_messages={"required": "username不能为空",})
password = forms.CharField(label=‘密码‘,widget=forms.PasswordInput(attrs={"placeholder": "密码", "required": "required",}),
max_length=20, error_messages={"required": "password不能为空",})views.py

else:
lf = form.LoginForm()
return render_to_response(‘index.html‘,{‘lf‘:lf})
#退出
def do_logout(request):
logout(request)
return HttpResponseRedirect(‘/‘)踩过的坑：
1、登陆的时候用自带的认证模块总是报none
user = authenticate(username=username, password=password)
查看源码发现是check_password的方法是用hash进行校验，之前注册的password写法是
user.password=password
这种写法是明文入库，需要更改密码的入库写法
user.set_password(password)
