    1. If you really know Django then you should appreciate drf because the only major difference is the serializer just like you would use modelform and forms.

  1. I passed the proper details into each of the views, but I am lost at the detailview page. My api is working perfectly save for the detailview page. I honestly am confused. Any help, please?

    # Project’s View.py
    class CommentGet(DetailView):
    model = Post
    template_name = “post_detail.html”

    def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    context[“form”] = CommentForm()
    return context

    class CommentPost(SingleObjectMixin, FormView):
    model = Post
    form_class = CommentForm
    template_name = “post_detail.html”

    def post(self, request, *args, **kwargs):
    self.object = self.get_object()
    return super().post(request, *args, **kwargs)

    def form_valid(self, form):
    comment = form.save(commit=False)
    comment.post = self.object
    comment.save()
    return super().form_valid(form)

    def get_success_url(self):
    post = self.get_object()
    return reverse(“post_detail”, kwargs={“pk”: post.pk})

    class PostDetailView(LoginRequiredMixin, View):
    def get(self, request, *args, **kwargs):
    view = CommentGet.as_view()
    return view(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
    view = CommentPost.as_view()
    return view(request, *args, **kwargs)

    # BlogAPi Views.py
    class CommentGet(DetailView):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

    def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    context[“form”] = CommentForm()
    return context

    class CommentPost(SingleObjectMixin, FormView):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

    def post(self, request, *args, **kwargs):
    self.object = self.get_object()
    return super().post(request, *args, **kwargs)

    def form_valid(self, form):
    comment = form.save(commit=False)
    comment.post = self.object
    comment.save()
    return super().form_valid(form)

    def get_success_url(self):
    post = self.get_object()
    return reverse(“post_detail”, kwargs={“pk”: post.pk})

    class PostDetailView(LoginRequiredMixin, View):
    def get(self, request, *args, **kwargs):
    view = CommentGet.as_view()
    return view(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
    view = CommentPost.as_view()
    return view(request, *args, **kwargs)

  2. I got this error “‘model’ object is not iterable” when accessing Todo_api/

    Had to use .filter instead of .get

    def get_object(self, todo_id, user_id):
    ”’
    Helper method to get the object with given todo_id, and user_id
    ”’
    try:
    return Todo.objects.filter(id=todo_id, user = user_id)
    except Todo.DoesNotExist:
    return None
