I've created relationshiop as below in the code. In 'tickets' table I use two foreign keys referring to 'users' table. When I use operator nad creator methods from Ticket model it works fine. But when I want to get ownerTickets or operatorTickets from User model i get null. I am not sure if I called these methods correctly.
My database is well filled, I see that user is either owner or operator.
class CreateTicketsTable extends Migration
{
public function up()
{
Schema::create('tickets', function (Blueprint $table) {
$table->increments('id');
$table->integer('owner_id')->unsigned();
$table->integer('operator_id')->unsigned()->nullable();
$table->timestamps();
$table->foreign('owner_id')->references('id')->on('users');
$table->foreign('operator_id')->references('id')->on('users');
});
}
/*...*/
}
class CreateUsersTable extends Migration
{
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->integer('position_id')->unsigned();
$table->rememberToken();
$table->timestamps();
$table->foreign('position_id')->references('id')->on('positions');
});
}
/*...*/
}
class Ticket extends Model {
/*...*/
public function owner() {
return $this->belongsTo(User::class, 'owner_id');
}
public function operator() {
return $this->belongsTo(User::class, 'operator_id');
}
}
class User extends Authenticatable {
/*...*/
public function ownerTickets() {
return $this->hasMany(Ticket::class, 'owner_id', 'id');
}
public function operatorTickets() {
return $this->hasMany(Ticket::class, 'operator_id', 'id');
}
}
Is there good solution for Eloquent model and this relationship? Should I change it?
What you showed is a good solution and there is no need to change it.
The relationships are working fine, for example with this code:
$user = User::find(1);
echo 'Owner ticket count: ' . $user->ownerTickets->count() . '<br>';
echo 'Operator ticket count: ' . $user->operatorTickets->count() . '<br>';
$ticket = Ticket::find(1);
echo 'Ticket owner ID: ' . $ticket->owner->id . '<br>';
echo 'Ticket operator ID: ' . $ticket->operator->id . '<br>';
