首先建立一個註冊使用者的程式：

  def register(request):
  #校驗請求方式，進入不同的處理函式
    if request.method == 'GET':
   		return render(request,'index.html',)
	elif request.method == 'POST':
    '''獲取前端頁面的資料'''
        print('進入')
        user_name = request.POST.get('username')
        password = request.POST.get('password')
        cpassword = request.POST.get('cpassword')
        emai = request.POST.get('email')
        #判斷資料是否為空
        if not all([user_name, password, cpassword, emai]):
            return render(request, 'index.html')
        #判斷郵箱是否規範
        if not re.match(r'^([a-zA-Z0-9_-])
 
[email protected]([a-zA-Z0-9_-])+((\.[a-zA-Z0-9_-]{2,3}){1,2})$', emai):
            return render(request, 'index.html',{'errmsg':'郵箱不符合規範'})


        #判斷是否重複操作
        #判斷郵箱：
        try:
            user_email = UserInfo.objects.filter(email__exact = emai )
            print(user_email)


        except Exception as e:
            user_email = None
        if user_email:
            return render(request, 'index.html', {'errmsg': '郵箱已經被使用'})


        #判斷使用者名稱
        try:
            user = UserInfo.objects.get(username = user_name)

        except Exception as e:
            user = None
        if user:
            return render(request, 'index.html', {'errmsg': '使用者名稱已經被使用'})

        #建立一個使用者物件
        user = UserInfo.objects.create_user(username=user_name, email=emai, password=password)
        #create_user 自帶檢查是否重複
        # create_user(self, username, email=None, password=None,

        #講啟用標誌設定為0
        user.is_active = 0
        user.save()
        print('提交成功')

        return render(request, 'index.html')
 

第二步，進行資料庫的校驗：

class RegisterView(View):
	def get(self,request):
    	return render(request, 'index.html')

	def post(self,request):
	#獲取使用者輸入的資訊
        user_name = request.POST.get('username')
        password = request.POST.get('password')
        cpassword = request.POST.get('cpassword')
        email = request.POST.get('email')
        '''判斷資料是否為空'''
        if not all([user_name, password, cpassword, email]):
            return render(request, 'index.html')

        if not re.match(r'^([a-zA-Z0-9_-])
 
[email protected]([a-zA-Z0-9_-])+((\.[a-zA-Z0-9_-]{2,3}){1,2})$', email):
            return render(request, 'index.html', {'errmsg': '郵箱不符合規範'})
		try:
        user = UserInfo.objects.filter(email__exact=email)
        （UserInfo是資料庫裡面存放使用者資訊的一張表，filter是模糊查詢，去匹配資料庫裡面的資訊）

  		 except Exception as e:
   	    	 user = None

        if user:
            return render(request, 'index.html', {'errmsg': '郵箱已經被使用'})

        '''判斷使用者名稱'''
        try:
            usern = UserInfo.objects.get(username=user_name)

        except Exception as e:
            usern = None

        if usern:
            return render(request, 'index.html', {'errmsg': '使用者名稱已經被使用'})

        '''建立一個使用者物件'''
        user = UserInfo.objects.create_user(username=user_name, password=password, email=email)
        # create_user(self, username, email=None, password=None,
        '''將啟用標誌設定為0'''
        user.is_active = 0
        user.save()
        print('提交成功')
