I am facing some issue here i am try to store only one object either school or college or work, but mongoose automatically create other two object.
how to omit other object. here i should use default
let mySchema = new Schema({
"type": { type: String, default: "" }, // school or college or work
"school": {
'name':{ type: String, default: "" },
'parent':{ type: String, default: "" },
'address':{ type: String, default: "" },
'email_id':{ type: String, default: "" },
'phone_no':{ type: String, default: "" },
},
"college": {
'name':{ type: String, default: "" },
'friend':{ type: String, default: "" },
'address':{ type: String, default: "" },
'email_id':{ type: String, default: "" },
'phone_no':{ type: String, default: "" },
},
"work": {
'name':{ type: String, default: "" },
'colleague':{ type: String, default: "" },
'address':{ type: String, default: "" },
'email_id':{ type: String, default: "" },
'phone_no':{ type: String, default: "" },
},
});
Is something avoiding you to set this programmatically?
const myType = "school"; // Just for example const mySchemaObj = { "type": { type: String, default: myType } }; mySchemaObj[myType] = { "school": { 'name':{ type: String, default: "" }, 'parent':{ type: String, default: "" }, 'address':{ type: String, default: "" }, 'email_id':{ type: String, default: "" }, 'phone_no':{ type: String, default: "" }, }, "college": { 'name':{ type: String, default: "" }, 'friend':{ type: String, default: "" }, 'address':{ type: String, default: "" }, 'email_id':{ type: String, default: "" }, 'phone_no':{ type: String, default: "" }, }, "work": { 'name':{ type: String, default: "" }, 'colleague':{ type: String, default: "" }, 'address':{ type: String, default: "" }, 'email_id':{ type: String, default: "" }, 'phone_no':{ type: String, default: "" }, } }[myType]; console.log(mySchemaObj); /* Then, later... let mySchema = new Schema(mySchemaObj); */
If you check this section from Mongoose docs, you will see that Mongoose always creates an empty object for nested documents (eg school
in your case).
You could use a subdocument instead, where school
, college
and work
are instances of Schema
.
What you can do:
const mySchema = new Schema({
school: new Schema({
name: { type: String },
parent: { type: String },
address: { type: String },
email_id: { type: String },
phone_no: { type: String },
}),
college: new Schema({
name: { type: String },
friend: { type: String },
address: { type: String },
email_id: { type: String },
phone_no: { type: String },
}),
work: new Schema({
name: { type: String },
colleague: { type: String },
address: { type: String },
email_id: { type: String },
phone_no: { type: String },
}),
});
const MyModel = mongoose.model('MyModel', mySchema);
const myDocument = new MyModel();
myDocument.college = { name: 'Harvard' };
await myDocument.save();
