Mongoose Schema with a nested optional object with required fields

Question

I would like to create a Mongoose schema that validates the object below with the following restrictions:

• field2 optional (ratio 0-1),
• field2.type is required if field 2 exists (note that the name of the field "type" is the reserved word mongoose for type definitions),
• field2, and the base object must be in the same document.

Code example

{ field1: "data", field2: { type: "data", data: "data" } } 

Thanks in advance.

Answer 1

You can reference this answer :

 { field1: "your data", field2: { type: { "your data" }, required:false } } 

So an example would be:

 { field1: String, field2: { type: { nestedField1:{type:String,required:true}, nestedField2:String }, required:false } } 

if field 2 exists then nestedField1 will be required.

Answer 2

you can keep in mind something like this:

 var Field2Schema = new mongoose.Schema({ type: { type: String, required: true }, data: String }); var MainSchema = new mongoose.Schema({ field1: String, field2: Field2Schema });
