How to pass a form view to another view as a context in django?

I'm using Django 1.8 to create an application. I have a Link model and a Comment model which has Link as a ForeignKey. I'm using generic views to generate a LinkDetailView and CommentCreateView and show them in separate template files and then include comment in link detail template. Here is the code:

views.py

class LinkDetailView(DetailView):
    models      = Link
    queryset    = Link.objects.all()

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

class CommentCreateView(CreateView):
    form_class  = CommentForm
    template_name = "comments/comment_form.html"


    def form_valid(self, form):
        link = get_object_or_404(Link, pk=form.data["link"] )
        f = form.save(commit=False)
        f.user = self.request.user
        f.link = link
        f.save()
        return super(CommentCreateView, self).form_valid(form)

link_detail.html

{% block content %}
 . . . 
{% include "comments/comment_form.html" %}
{% endblock %}

comment_form.html

<h2>Add Comment</h2>
<form action="" method="POST">
    {% csrf_token %}
    <table>
        {{ form.as_p }}
    </table>
    <input type="submit" name="submit" value="Submit" />
</form>

The form shows up in the link detail page but when I click submit button it goes to nowhere [I see error "POST /links/1/slug/ HTTP/1.1" 405 0 in shell] and obviously doesn't save in database.

I'm not sure if I've chosen correct approach to do this, so any help would be appreciated.

I've solved the problem using FormMixin here's the docs

and here's how the views.py looks like now:

class LinkDetailView(FormMixin, DetailView):
    models      = Link
    queryset    = Link.objects.all()

    form_class  = CommentForm

    def get_success_url(self):
        return reverse('link_detail', kwargs={'pk': self.object.pk, 'slug': self.object.slug})

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

    def post(self, request, *args, **kwargs):
        if not request.user.is_authenticated():
            return HttpResponseForbidden()
        self.object = self.get_object()
        form = self.get_form()
        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_invalid(form)

    def form_valid(self, form):
        link = get_object_or_404(Link, pk=self.object.pk)
        print link
        f = form.save(commit=False)
        f.user = self.request.user
        f.link = link
        f.save()
        return super(LinkDetailView, self).form_valid(form)
