DocumentArrayPath

DocumentArrayPath()

Parameters:
  • key «String»
  • schema «Schema»
  • options «Object»
  • schemaOptions «Object»
Inherits:

SubdocsArray SchemaType constructor

DocumentArrayPath.get()

Parameters:
  • getter «Function»
Returns:
  • «this»
Type:
  • «property»

Attaches a getter for all DocumentArrayPath instances

DocumentArrayPath.options

Type:
  • «property»

Options for all document arrays.

  • castNonArrays: true by default. If false, Mongoose will throw a CastError when a value isn't an array. If true, Mongoose will wrap the provided value in an array before casting.

DocumentArrayPath.prototype.discriminator()

Parameters:
  • name «String»
  • schema «Schema» fields to add to the schema for instances of this sub-class
  • [options] «Object|string» If string, same as options.value.
    • [options.value] «String» the string stored in the discriminatorKey property. If not specified, Mongoose uses the name parameter.
    • [options.clone=true] «Boolean» By default, discriminator() clones the given schema. Set to false to skip cloning.
Returns:
  • «Function» the constructor Mongoose will use for creating instances of this discriminator model
See:

Adds a discriminator to this document array.

Example: 

const shapeSchema = Schema({ name: String }, { discriminatorKey: 'kind' });
const schema = Schema({ shapes: [shapeSchema] });

const docArrayPath = parentSchema.path('shapes');
docArrayPath.discriminator('Circle', Schema({ radius: Number }));

DocumentArrayPath.schemaName

Type:
  • «property»

This schema type's name, to defend against minifiers that mangle function names.

DocumentArrayPath.set()

Parameters:
  • option «String» The name of the option you'd like to set (e.g. trim, lowercase, etc...)
  • value «Any» The value of the option you'd like to set.
Returns:
  • «void,void»
Type:

Sets a default option for all DocumentArray instances.

Example: 

// Make all numbers have option `min` equal to 0.
mongoose.Schema.DocumentArray.set('_id', false);
