在模型.py在

^{pr2}$

在表单.py在

from django import forms
from .models import Opretkunde
from django.forms import ModelForm



class Opret_kunde_form(ModelForm):
    class Meta:
        model = Opretkunde
        fields = ['Fornavn', 'Efternavn', 'Telefon', 'Adresse']

在视图.py在

from django.shortcuts import render
from .forms import Opret_kunde_form
# Create your views here.
def index(request):
    if request.method == 'POST': #Påbegynder starten af scriptet hvis der observeres en POST request
        form = Opret_kunde_form(request.POST, request.FILES) #initialiserer formen
        if form.is_valid():
            return render(request, 'createUser.html',)

Answer 1

Django模型子类models.Model，并且需要是一个类本身，因为这个类的实例将是一个模型实例。在

class Opretkunde(models.Model)
    # the rest of your model fields go here

这就是为什么会出现这个错误，函数没有属性_meta，因为函数不能有元类，只能有类。在
