【问题描述】:
我正在尝试使用“艺术家”的参考 ID 查询我的事件模型,以便我可以显示由给定艺术家主持的所有事件,但收到一个演员错误。下面的第四行是我如何尝试提取与给定艺术家相关的事件:
module.exports.showArtist = async (req, res,) => {
const artist = await Artist.findById(req.params.id).populate('events');
const artistId = "ObjectId(" + req.params.id + ")";
const event = await Event.find( { "artist": artistId });
if (!artist) {
req.flash('error', 'Cannot find that Artist');
return res.redirect('/artists');
}
res.render('artists/show', { artist });
}
我的代码顶部需要两个模型:
const Artist = require('../models/artist');
const Event = require('../models/event');
这是我的一个 mongodb 事件文档的外观 - 艺术家位于底部:
{ "_id" : ObjectId("6138c78e15832f41e263c601"),
"geometry" :
{ "type" : "Point",
"coordinates" : [ -97.748541, 30.269936 ]
},
"event_name" : "Friday night show",
"location" : "Austin, Tx 78745",
"description" : "Show at our Sam's Town Point",
"event_start" : ISODate("2021-09-11T03:00:00Z"),
"event_end" : ISODate("2021-09-11T04:25:00Z"),
"image" : "https://starbar.com",
"created" : ISODate("2021-09-08T14:24:14.399Z"),
"artist" : ObjectId("610f16a6ba0d5fc2d4593093"),
"__v" : 4,
"notification" : "30"
}
这是完整的错误 - 我做错了什么?
CastError: Cast to ObjectId failed for value "ObjectId(610f16a6ba0d5fc2d4593093)" (type string) at path "artist" for model "Event"
