Form not displaying when called by extended generic view

I'm trying to create a blog with comments. I've extended the generic DetailView so that I can save and display comments, but, although it seems to pass the information I want, nothing is displayed in the template.

Here is the code for the extended generic view.

class BlogDetailView(DetailView):
context ={}
form = CommentForm()
context['form'] = form
context_object_name = "comments"
model = Comments
def get_context_data(self, **kwargs):
    form = CommentForm()
    if self.request.method =='POST':
        if form.is_valid():
            t = form.save(commit=False)
            t.time = datetime.datetime.now()
            t.save()
            return HttpResponseRedirect(reverse('blog/blogpost_detail.html'))
    context = super(BlogDetailView, self).get_context_data(**kwargs)
    context['form'] = form
    context['comments'] = Comments.objects.all()
    return render(self.request, 'blog/blogpost_detail.html', context)

here is the code from the form I'm trying to pass

class CommentForm(forms.ModelForm):
class Meta:
  model = Comments
  fields=('commentText',)
  exclude =('post','commentTime','commentImage',)
  widgets={
        'commentText': forms.Textarea(attrs={'cols': 80, 'rows': 20}),
    }

and here is the relevant code from the template that I'm trying to display the form on.

    <!-- Post Content -->
<article>
    <div class="container">
        <div class="row">
            <div class="col-lg-8 col-lg-offset-2 col-md-10 col-md-offset-1">
    <table>
            {% for comment in comments %}
            <p>{{ comment }}</p>
            {% endfor %}
            <div class="test">
        <form role="form" method="post">
            <div class="input-group">
                {% csrf_token %}
                {{ form }}
                {% for field in form %}
                {{ field }}
                {% endfor %}
                <p>Comment: </p>
              <span class="input-group-btn">
            <button class="btn btn-default" type="submit">Submit</button>
            </span>
            </div>
        </form>
    </div>
    </table>
    </form>
            </div>
        </div>
    </div>
</article>

As of now, the page will load but the text field will not display. When I click the submit button it loads a blank page with the same url as before. I also think I might be missing some things as I am very new to Django.

Thanks for the help!
