如何在Mongoose中将架构属性设置为SubDocument类型？

Question

I want to do something like this:

var userSchema = new Schema({
  local: localSchema,
  facebook: facebookSchema,
  twitter: twitterSchema,
  google: googleSchema
});

But it seems that a Schema is not a valid SchemaType .

In the SubDocuments guide , they only give an example where the child schema is put inside of an array, but that isn't what I want to do.

var childSchema = new Schema({ name: 'string' });

var parentSchema = new Schema({
  children: [childSchema]
})

It looks like you're just trying to create a sub object for each of those properties. You can accomplish this one of two ways.

Embedded in the schema itself

var userSchema = new Schema({
    local: {
        someProperty: {type: String}
        //More sub-properties...
    }
    //More root level properties
});

Reusable object to be used in multiple schemas

//this could be defined in a separate module and exported for reuse
var localObject = {
    someProperty: {type: String}
    //more properties
}

var userSchema = new Schema({
    local: localObject
});

var someOtherSchema = new Schema({
    test: localObject
});
