Django1.7: ModelForm 没有指定模型 class

Question

我在 Django 中遇到 "ModelForm has no model class specified." 错误。我花了几个小时来解决这个问题，但看不出问题所在。

非常感谢您！

异常类型：/rango/add_category/
处的 ValueError 异常值：ModelForm 没有指定模型 class。

forms.py:

from django import forms
from rango.models import Page, Category

class CategoryForm(forms.ModelForm):
    name = forms.CharField(max_length=128, help_text="Please enter the category name.")
    views = forms.IntegerField(widget=forms.HiddenInput(), initial=0)
    likes = forms.IntegerField(widget=forms.HiddenInput(), initial=0)
    slug = forms.CharField(widget=forms.HiddenInput(), required=False)
    print name, views, likes, slug
    # An inline class to provide additional information on the form.
    class Mata:
        # Provide an association between the ModelForm and a model
        model = Category
        fields = ('name',)

views.py:

def add_category(request):

    if request.method=="POST":
        form = CategoryForm(request.POST)

        if form.is_valid():
            form.save(commit=True)

            return index(request)
        else:
            print form.errors
    else:
        form = CategoryForm()

    return render(request, 'rango/add_category.html', {'form': form})

改变

class Mata:

到

class Meta:

此外，我从未在模型窗体中看到打印语句。以防万一。
