Post request with Django DetailView gives error 'MyView' object has no attribute 'object'

Question

I am trying to create an object with django DetailView. My code is like that.

class Detail(DetailView):
    model = MyModel
    template_name = 'mymodel_detail.html'

    def get_context_data(self, **kwargs):
        context = super(Detail, self).get_context_data(**kwargs)
        context['form'] = DetailForm
        return context

    def post(self, request, *args, **kwargs):
        form = DetailForm(request.POST, request.FILES)
        if form.is_valid():
            context['reply_form'] = DetailForm
            self.object = super(Detail, self).get_object()
            context['object'] = super(Detail, self).get_object()

            return self.render_to_response(request=request, template=self.get_template_names(), context=context)
        else:
            context = context = super(Detail, self).get_context_data(**kwargs)
            context['reply_form'] = form
            self.object = super(Detail, self).get_object()
            context['object'] = super(Detail, self).get_object()

            return self.render_to_response(request=request, template=self.get_template_names(), context=context)

But here I am getting error that

'Detail' object has no attribute 'object'

I tried to assign object in context instance and with self as well. But nothing works.

What you are missing here is that you have to assign the object to the class or self before calling the get_context_data().

class Detail(DetailView):
    model = MyModel
    template_name = 'mymodel_detail.html'

    def get_context_data(self, **kwargs):
        context = super(Detail, self).get_context_data(**kwargs)
        context['form'] = DetailForm
        return context

    def post(self, request, *args, **kwargs):
        form = DetailForm(request.POST, request.FILES)
        if form.is_valid():
            # Write Your Logic here

            self.object = self.get_object()
            context = super(Detail, self).get_context_data(**kwargs)
            context['form'] = DetailForm
            return self.render_to_response(context=context)

        else:
            self.object = self.get_object()
            context = super(Detail, self).get_context_data(**kwargs)
            context['form'] = form
            return self.render_to_response( context=context)

and in render_to_response() Just pass context. No other arguments.

Hope it will work for you.
