One solution to this problem is to use polymorphic relationships in Laravel. This allows a single table to have multiple types of relationships with other tables.
First, create a "services" table with a "serviceable_id" and "serviceable_type" column. The "serviceable_id" column will store the ID of the related record, and the "serviceable_type" column will store the class name of the related record.
Next, create the different tables for each service (e.g. "table_a", "table_b", etc.) with their respective columns.
Then, in each of the models for the different tables, define a morphMany relationship to the "services" table:
class TableA extends Model
{
public function services()
{
return $this->morphMany(Service::class, 'serviceable');
}
}
Finally, in the "Service" model, define the inverse morphTo relationship:
class Service extends Model
{
public function serviceable()
{
return $this->morphTo();
}
}
Now, when you create a new service for a specific table, you can use the morphMany relationship to associate it with the correct record:
$tableA = TableA::find(1);
$service = new Service;
$tableA->services()->save($service);
You can also retrieve the related service for a specific record using the morphOne or morphMany relationship:
$tableA = TableA::find(1);
$service = $tableA->services()->first();
