**What**
- Allow to provide `foreignKeyName` option for hasOne and belongsTo relationships
- `model.hasOne(() => OtherEntity, { foreignKey: true, foreignKeyName: 'other_entity_something_id' })`
- The above will also output a generated type that takes into consideration the custom fk name 🔽
- Update types to account for defined custom foreign key name
- Fix joiner config linkable generation to account for custom linkable keys that provide a public API for their model but are not part of the list of the models included in the MedusaService
- This was supposed to be handled correctly but the implementation was not considering that custom linkable keys could reference models not part of the one provided to medusa service
- Migrate fulfillment module to DML
- Fix has one with fk behaviour and hooks (the relation should be assigned but not the fk)
- Fix has one belongsTo hooks (the relation should be assigned but not the fk)
- Fix hasOneWithFk and belongsTo non persisted fk to be selectable
- Allow to define `belongsTo` without other side definition for `ManyToOne` with no counter part defined
- Meaning that if a user defined `belongsTo` on one side andnot mapped by and no counter part on the other entity it will be considered as a `ManyToOne`
- `orphanRemoval` on `OneToOne` have been removed, this means that when assigning a new object relation to an entity, the previous one gets deconected but not deleted automatically. This prevent removing data un volountarely
**NOTE**
As per our convention here are some information to keep in mind
**HasOne <> BelongsTo**
Define `OneToOne`, The foreign key is owned by the belongs to and the relation needs to be provided to cascade if wanted
**HasMany <> BelongsTo**
Define `OneToMane` <> `ManyToOne`, the foreign key is owned by the many to one and for those relation no cascade will be performed, the foreign key must be provided. For the `HasMany` the cascade is available
**HasOne (with FK)**
Will act similarly to belongs to with **HasOne <> BelongsTo**
