我有以下架构:
var StorySchema = new Schema({
title: { type: String, required: true },
users: {
id: { type: Schema.ObjectId, ref: 'users' },
creator: { type: Boolean }
},
maxlines: { type: Number, default: '10'},
lines: {
text: { type: String },
entered_at: { type: Date },
user: {
id: { type: Schema.ObjectId, ref: 'users' }
}
},
created_date: { type: Date, default: Date.now },
updated_date: { type: Date, default: Date.now },
})
我有以下查询:
exports.view = function (req, res) {
Stories
.findOne({
_id: req.params.id
})
/*.populate('users') */ **<-- If I uncomment this I get the error**
.exec(function (err, story) {
if (err) {
res.json(200, {
success: "false",
message: err.message
})
} else if (story) {
res.json({
sucess: "true",
message: story
})
} else {
res.json(200, {
sucess: "false",
message: "story not found"
})
}
})
}
如上所述,如果我添加.populate('users')
,则会标记以下错误:
{
"success": "false",
"message": "Cast to ObjectId failed for value \"[object Object]\" at path \"_id\""
}
我正在调用/ view / 51fc2e02576f2dc058000001(这是故事表的对象ID),如果我调用它带回文档的URL,则没有.populate('users')
。
用户 - &gt; id值填充ObjectId("51fbe87ec137760025000001")
- 这是用户集合中的有效_id
我看不出我错过了什么?
添加了用户架构
var UserSchema = new Schema({
name: { type: String, required: true },
email: { type: String, required: true, unique: true },
username: { type: String, required: true, unique: true },
provider: { type: String, required: true, enum: ['local', 'facebook'] },
password: { type: String, required: true },
avatar: { type: String, default: 'http://i.imgur.com/1PtcFos.jpg' },
gender: { type: String, required: true, uppercase: true, enum: ['M', 'F'] },
facebook: {
id: { type: String },
token: { type: String },
token_expiry: { type: Date }
},
device: {
token: { type: String },
type: { type: String, enum: ['ios', 'android'] },
badge: { type: Number },
id: { type: String },
created_date: { type: Date, default: Date.now },
updated_date: { type: Date, default: Date.now }
},
created_date: { type: Date, default: Date.now },
updated_date: { type: Date, default: Date.now }
})
