博客的文章点赞功能,点赞一次+1,使用session记录当前用户问题点就是:在文章1进行点赞,文章2点赞就会提示已支持过了,原因判断出已存在session如何实现文章不能重复点赞View代码class LikeNumView(View): def post(self, request): if request.session.get('has_like', False): return HttpResponse('{"status":"fail", "msg":"已支持过"}', content_type='application/json') comments_id = request.POST.get("comments_id", "") blog = Blog.objects.get(id=int(comments_id)) blog.like_number += 1 blog.save() request.session['has_like'] = True return HttpResponse('{"status":"success", "msg":"感谢你的支持"}', content_type='application/json')ajax代码function like() { $.ajax({ cache: false, type: "POST", url: "{% url 'like' %}", data: {'comments_id':{{ comments.id }}}, async: true, beforeSend:function(xhr, settings){ xhr.setRequestHeader("X-CSRFToken", "{{ csrf_token }}"); }, success:function (data) { if (data.status=='fail'){ layer.msg("你已支持过") } else { layers.msg("感谢你的支持") } } }) }
