【问题描述】：

我收到此错误消息：值错误：ModelForm 没有指定模型类。并且花了几个小时试图修复它没有任何进展，我开始收到错误，在我添加了我的 forms.py 部分之后。我将展示我的 forms.py 然后是我的 views.py

from django.forms import ModelForm
from .models import Found

class FoundForm(ModelForm):
    class Meta: 
        model: Found
        fields = ['date', 'type']

```from django.shortcuts import render
```from .models import Rock #main app.models, models attribute. even photo models
```from .forms import FoundForm




```# Create your views here.views send data to our context dictionary
```def home(request):
    return render(request, 'home.html')

```def about(request):
    return render(request, 'about.html')

```def rocks_index(request):
    rocks = Rock.objects.all()
    return render(request, 'rocks/index.html', {'rocks': rocks})

```def rocks_detail(request, rock_id):
    rock = Rock.objects.get(id=rock_id)
    found_form = FoundForm()
    return render(request,'rocks/detail.html', {
        'rock': rock, 
        'found_form': found_form
    })

```class RockCreate(CreateView):
    model = Rock
    fields = '__all__' #class based view generate html5 forms

【解决方案1】：

将model: Found 替换为model = Found

class FoundForm(ModelForm):
    class Meta: 
        model = Found
        fields = ['date', 'type']

参考：Django ModelForm

更多type 是保留关键字，您还可以使用date 和DateTimeField。命名字段时最好保留保留的。
