Laravel - Relationships - Custom Pivot Models And Incrementing Ids
If you have defined a many-to-many relationship that uses a custom pivot model, and that pivot model has an auto-incrementing primary key, you should ensure your custom pivot model class defines an incrementing
property that is set to true
.
/**
* Indicates if the IDs are auto-incrementing.
*
* @var bool
*/
public $incrementing = true;
