Проблема при отправке формы. Почему при вводе в поле имя и категории пишет, что данного варианта нет среди допустимых значений?

Задача создать новую тему (topic) через форму. Когда ввожу в поле ввода name, category, то пишет: Выберите корректный вариант. Вашего варианта нет среди допустимых значений.

class TopicForm(forms.ModelForm):
    class Meta:
        model = Topic

        fields = ['name', 'category', 'author', 'content', 'tags']

        widgets = {
            'name': forms.TextInput(attrs={'class': 'form-control'}),
            'content': forms.Textarea(attrs={'class': 'form-control'}),
            'author': forms.TextInput(attrs={'class': 'form-control'}),
            'category': forms.TextInput(attrs={'class': 'form-control'}),
            'tags': forms.TextInput(attrs={'class': 'form-control'}),
        }

views.py

class TopicCreate(View):
    def get(self, request):
        form = TopicForm()
        return render(request, 'topic_create_form.html', context={'form': form})


    def post(self, request):
        bound_form = TopicForm(request.POST)
        if bound_form.is_valid():
            new_topic = bound_form.save()
            return redirect(new_topic)
        return render(request, 'create_top.html', context={'form': bound_form})
