Model Form Answer - my answers don't save!

Whenever I add an answer and click save, the answer doesn't save. I've run through the video a few times, and have double checked my views.py.

Can anyone spot the issue? Also it wont let me attach my code from workspace so had to copy it in.

answer_form.html -

{% extends "courses/layout.html" %} {% load course_extras %}

{% block title %}New Answer| {{ question.prompt }} | {{ question.quiz.course.title }} {{ block.super }}{% endblock %}

{% block breadcrumbs %} <li><a href="{% url 'courses:detail' pk=question.quiz.course.pk %}">{{ question.quiz.course.title }}</a></li> <li><a href="{% url 'courses:quiz' course_pk=question.quiz.course.pk step_pk=question.quiz.pk %}">{{ question.quiz.title }}</a></li> <li>{{ question.prompt }}</li> {% endblock %}

{% block content %} <div class="row columns"> {{ block.super }} <h1>Add Answer</h1> <form method="POST" action=""> {% csrf_token %} {{ form.as_p }} <input type="submit" class="button" value="Save"> </form> </div> {% endblock %}

answer form part of views.py -

@login_required def answer_form(request, question_pk): question =get_object_or_404(models.Question, pk=question_pk)

form = forms.AnswerForm()

if request.method == 'POST':
    form = forms.AnswerForm(request.POST)
    if form.is_valid:
        answer = form.save(commit=False)
        answer.question = question
        answer.save()
        messages.success(request, "Answer added")
        return HttpResponseRedirect(question.get_absolute_url())
return render(request, "courses/answer_form.html", {
    'question':question,
    'form':form
})

Thanks in advance!
