正則表達式電子郵件驗證django

在學校的項目上工作我知道如何做到這一點在燒瓶，但學習Django。我試圖確保在發佈之前輸入有效的電子郵件。如果我不做if if語句，表單會通過，但不會驗證它。我有以下內容，唯一不工作的部分是帶有註釋的部分，但是我包含了整個views.py，因此您可以看到頂部可能出錯的內容。正則表達式電子郵件驗證django

views.py

from django.shortcuts import render, redirect 
from .models import User 
import re 
EMAIL_REGEX = re.compile(r'^[a-zA-Z0-9.+_-][email protected][a-zA-Z0-9._-]+\.[a-zA-Z]+$') 

# Create your views here. 
def index(request): 

    return render(request, "emailvalidation/index.html") 


def create(request): 
    if request.method == 'POST':         #here down 

     if len(request.form['email']) < 1: 
      add_message("Invalid Email Address!")     #if i take out the if else the form does work 
     elif not EMAIL_REGEX.match(request.form['email']):    #the validation. 
      add_message("Invalid Email Address!") 
     else: 
      User.objects.create(email = request.POST['email'])  #to here 


     context ={ 

      "email": User.objects.all(), 
     } 

    return render(request, 'emailvalidation/success.html' ,context)

你的url模式是什麼樣的？ – Vallentin

而不是創建你自己的模式，你應該看看這個：https://docs.djangoproject.com/en/1.10/ref/validators/#validate-email –

request沒有form屬性。既然你已經有了if request.method == "POST" - 你可以放心地執行以下操作：

變化

request.form['email']

與

request.POST['email']

理想情況下，你應該使用django forms for handing the validations等Django表單有更好的驗證邏輯，正則表達式驗證器等。

LOL ty多數民衆贊成在從瓶子到Django在兩週內。 –

在那裏..做到了:) – karthikr
