python - csrf_token verification failed or aborted error with form

Question

I'm getting CSRF verification failed. Request aborted. My index view:

def index(request):
    tasks = Task.objects.all()

    form = TaskForm()

    if request.method == 'POST':
        form = TaskForm(request.POST)
        if form.is_valid():
            form.save()
        return redirect('/')

    context = {'tasks':tasks,'form':form}
    return render(request, 'tasks/list.html', context)

My list.html template with form:

<h3>TO DO</h3>
<form method="POST" action="/">
  {% csrf_token %}
  {{ form.title }}
  <input type="submit" name="" value="Create Task">
</form>
{% for task in tasks %}
  <div>
    <p>{{ task }}</p>
  </div>
{% endfor %}
