覆盖 POST 方法时对象没有属性 get

Question

class CreatePosts(CreateView):
    model = posts
    fields = ['title','comments']

    def post(self, request, *args, **kwargs):

        current_inspectionfile = Inspectionfile.objects.get(pk =   self.kwargs['pk'])
        new_post =   posts.objects.create(inspectionfile=current_inspectionfile,
                 title =request.POST.get("title"),
                 comments =request.POST.get("comments"))

       return new_post

型号

class posts(models.Model):
    inspectionfile = models.ForeignKey(Inspectionfile,   on_delete=models.CASCADE, default=1)
    title = models.CharField(max_length=120)
    comments = models.TextField()
    flag = models.BooleanField(default=False)

    def get_absolute_url(self):
       return reverse('posts_form', kwargs={'pk': self.pk})

    def __str__(self):
        return self.title

表单是一个简单的模板：

<form class = "form_horizontal" action = "" method = "post">
    {% csrf_token %}
    {{form.as_p}}
    <button type="submit">Submit</button>
    </form>


my url is:
url(r'^(?P<pk>[0-9]+)/$',views.CreatePosts.as_view(),name=='posts_form')

我收到的错误是

"posts" object has no attribute get.

我试过查看其他博客，但似乎无济于事。我已经覆盖了 CreatePosts class 中的 post 方法以某种方式工作。这就是我收到此错误的原因，还是因为某些 URL 不匹配。一旦用户点击提交，我希望他们返回相同的表单，因此 URL.

您的 post 方法是 return 您模型的一个实例

return new_post

所有视图都必须 return 一个 HttpResponse，因此在上下文中使用新的 post return 最简单的事情是 render

return render(request, self.template_name, {'new_post': new_post })

覆盖 POST 方法时对象没有属性 get

object has no attribute get while overriding the POST method
