喜欢和不喜欢用户对产品的角度评论

Question

用户架构：

var UserSchema = new Schema({
    review_likes :      [{type:String}],
    review_dislikes :   [{type:String}]
});

查看架构：

var ReviewSchema = new Schema({
    productID:{type: String, required: true},
    numoflikes:{type:Number, required:true},
    numofdislikes:{type:Number, required:true}
})

html：

</div>  

我正在尝试喜欢/不喜欢问题评论列表中的评论

我想将 1 个喜欢/不喜欢限制为 1 个用户的评论

这里发生的问题是，在 html 的显示中，字形图标立即成功更改，但 ng-bind="review.numoflikes" 和 ng-bind="review.numofdislikes" 的跨度并没有立即更新，而是页面刷新时更新

数据库正在成功更新

另外，如果你能帮助我限制用户只喜欢或不喜欢，那就太好了。谢谢。
