在django中将UpdateView表单与CreateView表单显示在同一页上

from django.views.generic import UpdateView, CreateView
from django.urls import reverse_lazy
from .models import YourModel
from .forms import YourForm

class FormView(UpdateView, CreateView):
    model = YourModel
    form_class = YourForm
    template_name = 'your_template.html'
    success_url = reverse_lazy('your_success_url')

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['update_form'] = self.get_form(self.get_form_class())
        context['create_form'] = self.get_form(self.get_form_class())
        return context

<form method="post">
  {% csrf_token %}
  {{ update_form.as_p }}
  {{ create_form.as_p }}
  <input type="submit" value="Save">
</form>
