Django POST数据通过表单重定向到，并用POST数据重定向到页面

Question

我有一个Django表单，一旦提交了数据，我想重定向到另一个显示数据的页面。

我遇到了麻烦，因为在表单提交之前，我不知道如何检索外键

表单

class addEventForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(addEventForm, self).__init__(*args, **kwargs)
class Meta:
model = Event
fields = '__all__'

查看

class addEventView(LoginRequiredMixin,View):
template_name = 'pages/add_event.html'
def get(self, request, *args, **kwargs):
return render(request, self.template_name)
def post(self, request, *args, **kwargs):
form = addEventForm(request.POST)
if form.is_valid():
form.save()
data = {"success": "successfully added"}
else:
data = {"error": form.errors}
return JsonResponse(data, safe=False)

JS-

onst xhr = new XMLHttpRequest();
xhr.open("POST", "/pages/add_event");
xhr.setRequestHeader("X-CSRFToken", csrftoken);
xhr.send(formdata);
xhr.onload = () => {
window.location.reload();
};

如何重定向但从POST中提取数据？

感谢

您可以使用CreateView和success_url

试试

from django.views.generic.edit import CreateView
from django.urls.base import reverse_lazy
class addEventView(LoginRequiredMixin, CreateView):
template_name = 'pages/add_event.html'
model = Event
form_class = addEventForm
success_url = reverse_lazy('url_name_you_want_to_redirect_to')

仅供参考：在python中，类名通常应该使用CapWords约定，因此最好分别将addEventForm更改为AddEventForm，将addEventView更改为AddEventView
