刷新页面后重新提交django表单

Question

我第一次提交表单然后刷新表单后，它会重新提交，我不想要

create_group.html：

<form id="create_group" class="form-horizontal" role="form" action="" method="post">
                        {% csrf_token %}
                        {% include 'whatsapp_blast/form_template.html' %}
                        <div class="form-group">
                            <div class="col-sm-offset-2 col-sm-10">
                                <button style="background-color:#FA4616;border: none;" type="submit" class="btn btn-primary">Submit</button>
                            </div>
                        </div>
                    </form>

views.py：

def create_group(request):
    groups = Group.objects.filter(user=request.user)
    print(groups)
    if request.method == "POST":
        print("In IF")
        form = GroupForm(request.POST)
        if form.is_valid():
            group = form.save(commit=False)
            group.user = request.user
            group.save()

            # Redirect to THIS view, assuming it lives in 'some app'
            return HttpResponseRedirect("whatsapp_blast.views.create_group")
    else:
        print("else")
        form = GroupForm(request.POST)
        print(form)
        context = {
            "form": form,
        }
    return render(request,'whatsapp_blast/create_group.html', context)
