域名反向解析：當路徑發生改變後固定路徑需要改變，通過反向解析可以自動尋找並修改

huasheng/urls.py下 新增namespace
url(r'^user/',include('user.urls',namespace='user')),
各應用urls.py下 新增name
url(r'^$', views.index,name='index'),
html模板中
<form action="{% url 'user:register' %}" method="POST">user找姓register找名

檢視函式和類檢視

views.py下
from django.shortcuts import render,redirect	#redirect重定向
from django.core.urlresolvers import reverse	#匯入反向解析函式
from django.http import HttpResponse
from .models import User
from django.views.generic import View		#匯入View類
class RegisterView(View):
    def get(self,request):			#當method為get時執行
        return render(request, 'register.html')
def post(self,request):			#當method是post時執行
    user_name = request.POST.get('user_name')
    pwd = request.POST.get('pwd')
    email = request.POST.get('email')
    allow = request.POST.get('allow')
    print(allow)
    # 校驗資料是否為空
    if not all([user_name, pwd, email, allow]):
        return HttpResponse('資料有為空的情況')
    # 校驗資料格式的情況
    user = User.objects.create_user(username=user_name, email=email, password=pwd)
    # username, email = None, password = None, ** extra_fields
    user.is_active = 0			#將is_active屬性改為0並儲存
    user.save()

    return redirect(reverse('carlist:index'))	#重定向到首頁

urls.py下更改
url(r'register/',views.RegisterView.as_view(),name='register')	#跳轉到views.RegisterView.as_view()判斷method
 

利用建立類的方式對預設表格進行修改

apps資料夾下建立db資料夾下base_model.py
from django.db import  models

class BaseModel(models.Model):
    is_delete = models.BooleanField(default=False,verbose_name='是否刪除')	#新增is_delete
    create_time = models.DateTimeField(auto_now_add=True,verbose_name='建立時間')	#新增create_time

    class Meta:
        abstract = True
    #註冊類
 

應用下models.py中

from db.base_model import BaseModel
from django.contrib.auth.models import AbstractUser

class User(AbstractUser,BaseModel):		#讓User類繼承BaseModel類將新屬性新增進預設表結構中
    pass
###***注意遷移出錯刪庫時不要忘記刪除對應migrations檔案

檢查郵箱是否被註冊

reemail = User.objects.filter(email=email)
if len(reemail)!=0:
            return HttpResponse('郵箱已被註冊')
 

更改密碼介面
寫好對應html，配置好url
veiw.py中新增新類ChangePwd

 class ChangePwd(View):

    def get(self,request):
        return render(request, 'changepwd.html')

    def post(self,request):
        user_name = request.POST.get('user_name')
        pwd = request.POST.get('pwd')
        new_pwd = request.POST.get('new_pwd')
        new_cpwd = request.POST.get('new_cpwd')
        # print(allow)
        # 校驗資料是否為空
        print(user_name)
        print(pwd)
        print(new_pwd)
        print(new_cpwd)
        if not all([user_name, pwd, new_pwd, new_cpwd]):
            return HttpResponse('資料有為空的情況')
        try:
            user = User.objects.get(username = user_name)
        except Exception:
            return HttpResponse('賬號不存在')


        if new_pwd!=new_cpwd:
            return HttpResponse('兩次密碼輸入不一致')
        if not user.check_password(pwd):
            print(user)
            return HttpResponse('密碼錯誤')
        # 校驗資料格式的情況
        user.set_password(new_pwd)
        user.save()
        # username, email = None, password = None, ** extra_fields

        return redirect(reverse('carlist:index'))
