我對 Django 模型有一些問題，我想迭代從基于模型的表單中的文本欄位獲取的資料。但我不能它仍然是一個錯誤：

代碼模型.py
from django.db import models
# Create your models here.
class Passwords(models.Model):
text = models.TextField(max_length=2000,null=True)
cipher = models.CharField(max_length=64)
def __str__(self):
return self.text
視圖.py
def start(request):
password_form = PasswordsForm(request.POST or None)
if password_form.is_valid():
text = password_form.save()
try:
for i in text:
value = (alphabet[i])
klucz = 10
new_value = int(value) klucz
if new_value > 70:
new_value = new_value - 70
for key, value in alphabet.items():
if value == str(new_value):
print(key, end='')
return ''
except KeyError:
return ('Nie znaleziono warto?ci' i ' w s?owniku!')
return render(request, 'kod.html', {'kod': kod})
return render(request, 'start.html', {'password_form': password_form})
我將不勝感激！

password = password_form.save()
try:
for i in password.text:
# …
