考虑下面提到的document
const testSchema = new mongoose.Schema({
test1: {
name: String,
email: String
},
test2: {
name: String,
email: String
}
test3: {
name: String,
email: String
}
test4: {
name: String,
email: String
}
});
在上述模型test1, test2, test3...
中,重复数据已存在。有办法避免这种方法吗?

假设您的架构保留了可以存储的记录列表,例如
const RecordsSchema = new mongoose.Schema({
name: { //
type: String, //
required: true, // dummy
maxLength: 254 //
}, //
tests: {
type: [mongoose.Schema.ObjectId],
ref: 'TestSchema',
required: false
}
}
const TestSchema = new mongoose.Schema({
name: {
type: String,
required: true,
maxLength: 254
},
email: {
type: String,
required: true,
maxLength: 254,
trim: true
}
}
这样,您将创建一个模型,该模型将独立定义每个测试,然后您的控制器可以将该Test对象链接到RecordsSchema模型中的数组
