Django ajax关注和取消关注

def user_follow(request):    user_id = request.POST.get('id', None)    action = request.POST.get('action', '')    FOLLOW_ACTION = 'follow'    UNFOLLOW_ACTION = 'unfollow'    if request.user.is_anonymous:        return JsonResponse({ 'status':'ko', 'message': 'You must login'}        )    if action not in [FOLLOW_ACTION, UNFOLLOW_ACTION]:        return JsonResponse({ 'status':'ko', 'message': 'Unknown action {}'.format(action)}        )    try:        user = User.objects.get(id=user_id)        if action == UNFOLLOW_ACTION: Contact.objects.filter(user_from=request.user,user_to=user).delete() return JsonResponse({     'status':'ok'     })        else: contact, created = Contact.objects.get_or_create( user_from=request.user, user_to=user) return JsonResponse({     'status':'ok',     'message': 'Following id : {}'.format(contact.id) })    except User.DoesNotExist:        return JsonResponse({ 'status':'ko' 'message': 'user id: does not exist: {}'.format(user_id)        })

您将关注和取消关注混为一谈，如果取消关注则创建联系人。

模板：

{% if request.user != user %}  <a> Follow ....{% endif %}
