在旧数据库选项卡中注册用户

Question

我是Django的新手，想知道我是否需要在我在数据库中创建的表中注册用户，或者将来我可以注册一个表“产品”或“帮助台”

我的项目是帮助台。 我的应用程序正在登录

login\view.py

from .forms import Testecadastro

def cadastro(request):
form = Testecadastro(request.POST or None)
if request.method == 'POST':
        form.save()
return render(request, 'cad.html', {'form': form})

login\forms.py

from django import forms
from .models import Testecadastro

class TesteCadastro(forms.ModelForm):
class Meta:
    model = Testecadastro
    fields = ['username', 'password']
    widgets = {
        'username': forms.TextInput(attrs={'class': 'form-control', 'maxlength': 255}),
        'password': forms.PasswordInput(attrs={'class': 'form-control', 'maxlengeth': 255})
    }

login\model.py

class Testecadastro(models.Model):
first_name = models.CharField(max_length=100, blank=True, null=True)
last_name = models.CharField(max_length=100, blank=True, null=True)
email = models.CharField(max_length=100, blank=True, null=True)
username = models.CharField(max_length=100, blank=True, null=True)
password = models.CharField(max_length=100, blank=True, null=True)

class Meta:
    managed = True
    db_table = 'Testecadastro'

login\url.py

from .views import cadastro
from .views import user_login
from django.urls import path
from django.conf import settings

urlpatterns = [
path('teste/', cadastro, name='cadastro'),
path('login/', user_login, name='login')

url.py

app_name = 'helpdesk'
urlpatterns = [
path('admin/', admin.site.urls),
path('teste/', include(login_urls)),
path('login/', include(login_urls))

login\templates\cad.html

{% extends 'base.html' %}
{% block content %}
    <form  method="post" class="form-signin">
        {% csrf_token %}
        <h2 class="form-signin-heading">Login</h2>
        <label>Usuário:</label>
        {{ form.username }}
        {{ form.username.errors }}
        <label>Password:</label>
        {{ form.password }}
        {{ form.password.errors }}
        <br>
        <button class="btn btn-lg btn-primary btn-block" 
type="submit">Entrar</button>
    </form>
{% endblock %}

错误：int（）参数必须是字符串、类似字节的对象或数字，而不是“QueryDict”
