如何在一个HTML页面Django中使用两个不同的函数

Question

我想创建一个网站，在那里我可以列出所有创建的表单，也可以在同一页面中创建表单。但是我想不出来。首先，我尝试使用两个链接到同一HTML文件的类，但后来我发现这是错误的，然后我尝试使用get post和get_queryset函数将这两个类写在一个类中。但是现在我只能创建表单，如果我删除get函数，我可以列出创建的表单

非常感谢，下面是我的views.py和HTML

views.py

from django.shortcuts import render,redirect
from django.contrib.auth.decorators import login_required
from django.views import generic
from .models import PostModel
from .forms import PostForm


# Create your views here.
class PostList(generic.ListView):
    template_name = 'home.html'
    form_class=PostForm

    def get_queryset(self):
        return PostModel.objects.order_by('-created_on')

    def get(self, request, *args, **kwargs):
        form = self.form_class()
        return render(request, self.template_name, {'form': form})

    def post(self,request,*args, **kwargs):
        form=self.form_class(request.POST)
        if form.is_valid():
            form.save()
            return redirect('home')
        return render(request,self.template_name,{'form':form})


class PostDetail(generic.DetailView):
    model = PostModel
    template_name = 'post_detail.html'

home.html

如果我正确理解了这个问题，您可以使用CreateView而不是ListView，并从get_context_data返回上下文中的帖子列表

class PostList(generic.CreateView):
    template_name = 'home.html'
    form_class=PostForm
    model = Post
    
    def get_context_data(self, **kwargs)
        context = super().get_context_data(**kwargs)
        context ['postmodel_list'] = PostModel.objects.order_by('-created_on')
        return context
