/**

|
* Schema constructor.
|
||
|
*
|
||
|
* ####Example:
|
||
|
*
|
||
|
* var child = new Schema({ name: String });
|
||
|
* var schema = new Schema({ name: String, age: Number, children: [child] });
|
||
|
* var Tree = mongoose.model('Tree', schema);
|
||
|
*
|
||
|
* // setting schema options
|
||
|
* new Schema({ name: String }, { _id: false, autoIndex: false })
|
||
|
*
|
||
|
* ####Options:
|
||
|
*
|
||
|
* - [autoIndex](/docs/guide.html#autoIndex): bool - defaults to null (which means use the connection's autoIndex option)
|
||
|
* - [autoCreate](/docs/guide.html#autoCreate): bool - defaults to null (which means use the connection's autoCreate option)
|
||
|
* - [bufferCommands](/docs/guide.html#bufferCommands): bool - defaults to true
|
||
|
* - [capped](/docs/guide.html#capped): bool - defaults to false
|
||
|
* - [collection](/docs/guide.html#collection): string - no default
|
||
|
* - [id](/docs/guide.html#id): bool - defaults to true
|
||
|
* - [_id](/docs/guide.html#_id): bool - defaults to true
|
||
|
* - [minimize](/docs/guide.html#minimize): bool - controls [document#toObject](#document_Document-toObject) behavior when called manually - defaults to true
|
||
|
* - [read](/docs/guide.html#read): string
|
||
|
* - [writeConcern](/docs/guide.html#writeConcern): object - defaults to null, use to override [the MongoDB server's default write concern settings](https://docs.mongodb.com/manual/reference/write-concern/)
|
||
|
* - [shardKey](/docs/guide.html#shardKey): object - defaults to `null`
|
||
|
* - [strict](/docs/guide.html#strict): bool - defaults to true
|
||
|
* - [strictQuery](/docs/guide.html#strictQuery): bool - defaults to false
|
||
|
* - [toJSON](/docs/guide.html#toJSON) - object - no default
|
||
|
* - [toObject](/docs/guide.html#toObject) - object - no default
|
||
|
* - [typeKey](/docs/guide.html#typeKey) - string - defaults to 'type'
|
||
|
* - [typePojoToMixed](/docs/guide.html#typePojoToMixed) - boolean - defaults to true. Determines whether a type set to a POJO becomes a Mixed path or a Subdocument
|
||
|
* - [useNestedStrict](/docs/guide.html#useNestedStrict) - boolean - defaults to false
|
||
|
* - [validateBeforeSave](/docs/guide.html#validateBeforeSave) - bool - defaults to `true`
|
||
|
* - [versionKey](/docs/guide.html#versionKey): string - defaults to "__v"
|
||
|
* - [collation](/docs/guide.html#collation): object - defaults to null (which means use no collation)
|
||
|
* - [selectPopulatedPaths](/docs/guide.html#selectPopulatedPaths): boolean - defaults to `true`
|
||
|
* - [skipVersioning](/docs/guide.html#skipVersioning): object - paths to exclude from versioning
|
||
|
* - [timestamps](/docs/guide.html#timestamps): object or boolean - defaults to `false`. If true, Mongoose adds `createdAt` and `updatedAt` properties to your schema and manages those properties for you.
|
||
|
* - [storeSubdocValidationError](/docs/guide.html#storeSubdocValidationError): boolean - Defaults to true. If false, Mongoose will wrap validation errors in single nested document subpaths into a single validation error on the single nested subdoc's path.
|
||
|
*
|
||
|
* ####Options for Nested Schemas:
|
||
|
* - `excludeIndexes`: bool - defaults to `false`. If `true`, skip building indexes on this schema's paths.
|
||
|
*
|
||
|
* ####Note:
|
||
|
*
|
||
|
* _When nesting schemas, (`children` in the example above), always declare the child schema first before passing it into its parent._
|
||
|
*
