Code models.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

views.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 wartości'   i   ' w słowniku!')

            return render(request, 'kod.html', {'kod': kod})

    return render(request, 'start.html', {'password_form': password_form})

I would be grateful for help!!

CodePudding user response：

The text is a Password object, not a string. You should iterate over the password so:

password_form = PasswordsForm(request.POST or None)
if password_form.is_valid():
    password = password_form.save()
    try:
        for i in password.text:
            # …
    except KeyError:
        # …
