我正在与MongoDB和Mongoose构建一个反应应用程序。我有看护人和病人。
我在登录后抓住看护人ID并使用它来填充"患者"与该看守相关联。但出于某种原因,我无法弄清楚为什么我的看守人系列本身(Caretaker)而不是来自"患者"集合。
患者模型:
const patientSchema = new Schema({
firstName: {type: String, required: true},
lastName: {type: String, required: true},
address: {type: String, required: true},
address2: {type: String},
city: {type: String, required: true},
state: {type: String, required: true},
zip: {type: String, required: true},
preferredLanguage: {type: String, required: true},
medicalCond: {type: String, required: true},
medication: {type: String},
allergies: {type: String},
notes: {type: String},
primaryCareName: {type: String},
primaryCareNumber: {type: String},
contactFirstName: {type: String, required: true},
contactLastName: {type: String, required: true},
contactRelationship: {type: String, required: true},
contactNumb: {type: String, required: true}
});
看守模型:
const caretakerSchema = new Schema({
username: {type: String, unique: true, required: true},
password: {type: String, required: true},
phoneNumb: {type: String, required: true},
local: {
username: {type: String, unique: true},
password: {type: String, unique: true}
},
patient: [{
type: Schema.Types.ObjectId,
ref: "Patient"
}]
});
在上述患者密钥中,它填写了非患者登记的看护人的价值。
这是我的代码.populate
findById: function(req, res) {
db.Caretaker
.findOne({_id: req.params.id})
.populate("patient")
.then(dbModel => res.json(dbModel))
.catch(err => res.status(422).json(err));
}
答案 0 :(得分:0)
所以在你的例子中你:
