Class: MorphMany<OM, TM, PKT, FT, PKF, FKID>
Represents a relationship between two models where the table and primary key of the foreign model stored as a property of the originating model.
Description
For example, a user has many contactMethod which can be either an email or a phone_number:
In your configuration you would have:
typescript
{
...
models: {
users: {
schema: '++id, contact_method_type, contact_method_id, password, createdAt, updatedAt',
properties: ['id', 'contact_method_type', 'contact_method_id', 'password', 'createdAt', 'updatedAt'],
primaryKey: 'id',
relationships: {
contactMethod: [MorphMany, 'contact_method_type', 'contact_method_id'],
}
},
emails: {
schema: '++id, address',
properties: ['id', 'address'],
primaryKey: 'id',
},
phone_numbers: {
schema: '++id, number',
properties: ['id', 'number'],
primaryKey: 'id',
},
}Which will then allow you to access the contact methods of a user from the contactMethod accessor on the user model: user.contactMethod.
Remarks
The inverse of this relationship is the MorphTo relationship. Configured using the MorphManyConfiguration tuple.
