表单提交的内容为什么没有显示出来，提交后都显示的默认的title和content。并且刷新页面后重复提交
def edit_action(request):
title = request.POST.get("title","TITLE")
content = request.POST.get("content","CONTENT")
models.Article.objects.create(title=title, content=content)
articles = models.Article.objects.all()
return render(request, "index.html", {"articles": articles})
