我正在尝试使用AJAX在Django中实现一个赞按钮。我的模型是:

class post(models.Model):
    Profile=models.ForeignKey(Profile,on_delete=models.CASCADE)
    Picture=models.ImageField(upload_to='PostMedia',blank=True,null=True)
    DatePosted=models.DateTimeField(default=timezone.now)
    Content=models.TextField(blank=True,null=True)
    user_like=models.ManyToManyField(User,related_name="likes",blank=True)

    def __str__(self):
        return self.Profile.user.username

    @property
    def totallikes(self):
        return self.user_like.count()

    class Meta:
        ordering=['-DatePosted']

    @property
    def like_count(self):
        return len(likes.objects.filter(post=self))

我的网址是:-

 path('like/',views.like_button,name='like_button'),

我的查看功能是:-

def like_button(request):
if request.method=='POST':
    user=request.user
    postobject=get_object_or_404(post,pk=id)
    if postobject.likes.filter(id=user.id).exists():
        postobject.likes.remove(user)
    else:
        postobject.likes.add(user)

    context={'likes_count':postobject.total_likes}
    return HttpResponse(json.dumps(context),content_type='application/json')

最终模板是:-

{% for p in result %}
    <div class="SpriteContainer">
      <input type="button" class="like" name="{{ p.id }}" value="Like">
      <p>{{ p.totallikes }}</p>

    </div>
    {% endfor %}
<script>
$('.like').click(function(){
    var pk=$(this).attr('name')
    $.ajax({
        type:"POST"
        url:"{% url 'like_button' %}"
        data:{'pk':pk,'csrfmiddlewaretoken':'{{ csrf_token }}'}
        dataType:"json"
        success:function(response){
            alert('Company likes count is now'+response.count_likes);
        }
        error:function(rs,e){
            alert('Something went wrong')
        }
    });
})

当我在django admin中查看帖子条目时,还有一件事,它已经与所有可能的用户建立了多对多的关系。这是对的吗? enter image description here
