/**
|
||
|
|
* Converts this document into a plain-old JavaScript object ([POJO](https://masteringjs.io/tutorials/fundamentals/pojo)).
|
||
|
|
*
|
||
|
|
* Buffers are converted to instances of [mongodb.Binary](http://mongodb.github.com/node-mongodb-native/api-bson-generated/binary.html) for proper storage.
|
||
|
|
*
|
||
|
|
* ####Options:
|
||
|
|
*
|
||
|
|
* - `getters` apply all getters (path and virtual getters), defaults to false
|
||
|
|
* - `aliases` apply all aliases if `virtuals=true`, defaults to true
|
||
|
|
* - `virtuals` apply virtual getters (can override `getters` option), defaults to false
|
||
|
|
* - `minimize` remove empty objects, defaults to true
|
||
|
|
* - `transform` a transform function to apply to the resulting document before returning
|
||
|
|
* - `depopulate` depopulate any populated paths, replacing them with their original refs, defaults to false
|
||
|
|
* - `versionKey` whether to include the version key, defaults to true
|
||
|
|
* - `flattenMaps` convert Maps to POJOs. Useful if you want to JSON.stringify() the result of toObject(), defaults to false
|
||
|
|
* - `useProjection` set to `true` to omit fields that are excluded in this document's projection. Unless you specified a projection, this will omit any field that has `select: false` in the schema.
|
||
|
|
*
|
||
|
|
* ####Getters/Virtuals
|
||
|
|
*
|
||
|
|
* Example of only applying path getters
|
||
|
|
*
|
||
|
|
* doc.toObject({ getters: true, virtuals: false })
|
||
|
|
*
|
||
|
|
* Example of only applying virtual getters
|
||
|
|
*
|
||
|
|
* doc.toObject({ virtuals: true })
|
||
|
|
*
|
||
|
|
* Example of applying both path and virtual getters
|
||
|
|
*
|
||
|
|
* doc.toObject({ getters: true })
|
||
|
|
*
|
||
|
|
* To apply these options to every document of your schema by default, set your [schemas](#schema_Schema) `toObject` option to the same argument.
|
||
|
|
*
|
||
|
|
* schema.set('toObject', { virtuals: true })
|
||
|
|
*
|
||
|
|
* ####Transform
|
||
|
|
*
|
||
|
|
* We may need to perform a transformation of the resulting object based on some criteria, say to remove some sensitive information or return a custom object. In this case we set the optional `transform` function.
|
||
|
|
*
|
||
|
|
* Transform functions receive three arguments
|
||
|
|
*
|
||
|
|
* function (doc, ret, options) {}
|
||
|
|
*
|
||
|
|
* - `doc` The mongoose document which is being converted
|
||
|
|
* - `ret` The plain object representation which has been converted
|
||
|
|
* - `options` The options in use (either schema options or the options passed inline)
|
||
|
|
*
|
||
|
|
* ####Example
|
||
|
|
*
|
||
|
|
* // specify the transform schema option
|
||
|
|
* if (!schema.options.toObject) schema.options.toObject = {};
|
||
|
|
* schema.options.toObject.transform = function (doc, ret, options) {
|
||
|
|
* // remove the _id of every document before returning the result
|
||
|
|
* delete ret._id;
|
||
|
|
* return ret;
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* // without the transformation in the schema
|
||
|
|
* doc.toObject(); // { _id: 'anId', name: 'Wreck-it Ralph' }
|
||
|
|
*
|
||
|
|
* // with the transformation
|
||
|
|
* doc.toObject(); // { name: 'Wreck-it Ralph' }
|
||
|
|
*
|
||
|
|
* With transformations we can do a lot more than remove properties. We can even return completely new customized objects:
|
||
|
|
*
|
||
|
|
* if (!schema.options.toObject) schema.options.toObject = {};
|
||
|
|
* schema.options.toObject.transform = function (doc, ret, options) {
|
||
|
|
* return { movie: ret.name }
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* // without the transformation in the schema
|
||
|
|
* doc.toObject(); // { _id: 'anId', name: 'Wreck-it Ralph' }
|
||
|
|
*
|
||
|
|
* // with the transformation
|
||
|
|
* doc.toObject(); // { movie: 'Wreck-it Ralph' }
|
||
|
|
*
|
||
|
|
* _Note: if a transform function returns `undefined`, the return value will be ignored._
|
||
|
|
*
|
||
|
|
* Transformations may also be applied inline, overridding any transform set in the options:
|
||
|
|
*
|
||
|
|
* function xform (doc, ret, options) {
|
||
|
|
* return { inline: ret.name, custom: true }
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* // pass the transform as an inline option
|
||
|
|
* doc.toObject({ transform: xform }); // { inline: 'Wreck-it Ralph', custom: true }
|
||
|
|
*
|
||
|
|
* If you want to skip transformations, use `transform: false`:
|
||
|
|
*
|
||
|
|
* schema.options.toObject.hide = '_id';
|
||
|
|
* schema.options.toObject.transform = function (doc, ret, options) {
|
||
|
|
* if (options.hide) {
|
||
|
|
* options.hide.split(' ').forEach(function (prop) {
|
||
|
|
* delete ret[prop];
|
||
|
|
* });
|
||
|
|
* }
|
||
|
|
* return ret;
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* const doc = new Doc({ _id: 'anId', secret: 47, name: 'Wreck-it Ralph' });
|
||
|
|
* doc.toObject(); // { secret: 47, name: 'Wreck-it Ralph' }
|
||
|
|
* doc.toObject({ hide: 'secret _id', transform: false });// { _id: 'anId', secret: 47, name: 'Wreck-it Ralph' }
|
||
|
|
* doc.toObject({ hide: 'secret _id', transform: true }); // { name: 'Wreck-it Ralph' }
|
||
|
|
*
|
||
|
|
* If you pass a transform in `toObject()` options, Mongoose will apply the transform
|
||
|
|
* to [subdocuments](/docs/subdocs.html) in addition to the top-level document.
|
||
|
|
* Similarly, `transform: false` skips transforms for all subdocuments.
|
||
|
|
* Note that this is behavior is different for transforms defined in the schema:
|
||
|
|
* if you define a transform in `schema.options.toObject.transform`, that transform
|
||
|
|
* will **not** apply to subdocuments.
|
||
|
|
*
|
||
|
|
* const memberSchema = new Schema({ name: String, email: String });
|
||
|
|
* const groupSchema = new Schema({ members: [memberSchema], name: String, email });
|
||
|
|
* const Group = mongoose.model('Group', groupSchema);
|
||
|
|
*
|
||
|
|
* const doc = new Group({
|
||
|
|
* name: 'Engineering',
|
||
|
|
* email: 'dev@mongoosejs.io',
|
||
|
|
* members: [{ name: 'Val', email: 'val@mongoosejs.io' }]
|
||
|
|
* });
|
||
|
|
*
|
||
|
|
* // Removes `email` from both top-level document **and** array elements
|
||
|
|
* // { name: 'Engineering', members: [{ name: 'Val' }] }
|
||
|
|
* doc.toObject({ transform: (doc, ret) => { delete ret.email; return ret; } });
|
||
|
|
*
|
||
|
|
* Transforms, like all of these options, are also available for `toJSON`. See [this guide to `JSON.stringify()`](https://thecodebarbarian.com/the-80-20-guide-to-json-stringify-in-javascript.html) to learn why `toJSON()` and `toObject()` are separate functions.
|
||
|
|
*
|
||
|
|
* See [schema options](/docs/guide.html#toObject) for some more details.
|
||
|
|
*
|
||
|
|
* _During save, no custom options are applied to the document before being sent to the database._
|
||
|
|
*
|
||
|
|
* @param {Object} [options]
|
||
|
|
* @param {Boolean} [options.getters=false] if true, apply all getters, including virtuals
|
||
|
|
* @param {Boolean} [options.virtuals=false] if true, apply virtuals, including aliases. Use `{ getters: true, virtuals: false }` to just apply getters, not virtuals
|
||
|
|
* @param {Boolean} [options.aliases=true] if `options.virtuals = true`, you can set `options.aliases = false` to skip applying aliases. This option is a no-op if `options.virtuals = false`.
