我想在访问Image模型时显示commentCount
字段。这是代码:
imageSchema
.virtual('commentCount')
.get(async function () {
const image_id = this._id;
const commentCount = await Comment.count({ image_id });
return commentCount;
});
在图像的最终输出中,我得到:
{ uploaded: 2018-05-04T09:24:46.063Z,
_id: 5aec26ed56d4491ef4b3d15a,
title: 'Another snake',
description: 'Lorem ipsum dolor sit, amet consectetur adipisicing elit. Exercitationem ipsa autem culpa ea enim itaque, illo inventore obcaecati commodi minus?',
photo: '4a0831c2-f8d0-459d-ab06-794ee26c6c87.jpeg',
__v: 0,
commentCount: Promise { <pending> },
id: '5aec26ed56d4491ef4b3d15a' } ]
commentCount是一个承诺,即使在我等待Promise之后。我该如何解决这个问题?
答案 0 :(得分:0)
请在创建架构时尝试此操作:
var imageSchema= new Schema({
commentCount : {type: mongoose.Schema.Types.count, ref: 'Comment'},
pid: String,
oFile: String
});
