Question

我构建了一个包含两个字段的FormView。我想使用表单将查询传递给视图。

class SectorForm(forms.Form):
    date = forms.DateField()
    days = forms.IntegerField(max_value=365, min_value=1)

有没有办法可以从有效的表单字段中获取FormView并构建 success_url ？

重写get_success_url。

      def get_success_url(self): 
        return reverse_lazy('queryable-view' date days)

我以为我可以从form_valid中取出它但从未取得过成功。

Answer 1

get_success_url无法访问Form个实例，但form_valid可以访问from django.shortcuts import redirect class YourFormView(FormView): # ... def form_valid(self, form): date, days = form.cleaned_data['date'], form.cleaned_data['days'] return redirect('queryable-view', date, days)个实例。尝试这样的事情：

{{1}}

Answer 2

我曾遇到过类似的问题。当您使用表单时，您可能不会使用kwargs并且get_success_url无法访问表单（如前所述）我已经到处了：

class YourView(CreateView):
appointment_id =0

def form_valid(self,form):
    appointment = form.save()
    self.appointment_id = appointment.pk
    print self.appointment_id

    return super(AppointmentCreate,self).form_valid(form)

def get_success_url(self, **kwargs):         
    if  kwargs != None:
        return reverse_lazy('payment', kwargs = {'appid': self.appointment_id})

Django Success_url
