Question

我无法将表单数据保存到数据库中，每次尝试时，都会收到另一个错误。

这是我的表单模型

    class Meta:
        model = Asistente
        exclude = ('evento',)
        widgets = {'nombre': forms.TextInput(attrs={'class': 'form-control'}),
                   'telefono': forms.TextInput(attrs={'class': 'form-control'}),
                   'num_asistentes': forms.TextInput(attrs={'class': 'form-control'})}

这是我认为的代码。

    def post(self, request, evento_id):
        evento = Evento.objects.filter(id=evento_id).first()
        form = RegistroAsistenteForm(request.POST)

        if form.is_valid():
            registro_asistente = form.save(commit=False)
            registro_asistente.evento.pk = evento_id
            registro_asistente.save()
        else:
            form = RegistroAsistenteForm()

        return HttpResponseRedirect('/evento-reg/' + str(evento_id) + '/asistente/')```

There are times when I don't get any error, it just don't do anything.

您的视图应外观

def post(request, evento_id):
    if request.method == 'POST':
       evento = Evento.objects.filter(id=evento_id).first()
       form = RegistroAsistenteForm(request.POST)
       if form.is_valid():
           registro_asistente.evento = evento
           form.save()
           #to get the id u can us form.instance.id
           return redirect('to what ever u want from you urls')

    else:
       form = RegistroAsistenteForm()

    return HttpResponseRedirect('/evento-reg/' + str(evento_id) + '/asistente/')```

这就是在视图中收集您想做的事情的过程，它不需要自我
