I'm getting the results for all users - help please

[Rob Trehy]

Hi, I'm struggling to get this right and probably need another set of eyes over it if you can please!

I have three models; User, Session, SessionLap

Users have many Sessions and each Session has many Users (via session_drivers table)

User has many SessionLaps (has user_id and session_id fields)

I have the following relationships

User Model

public function sessions(): HasMany
{
    return $this->hasMany(Session::class);
}

public function laps()
{
    return $this->hasManyDeep(
        SessionLap::class,
        ['session_drivers', Session::class],
        ['user_id', 'id'],
    );
}

Sessions Model

public function users()
{
   return $this->belongsToMany(User::class, 'session_drivers', 'session_id', 'user_id');
}

I'm trying to load the relationship with the following:
Session::where('id', 1)->with(['users', 'users.laps'])->get();

However, whilst I can correctly see the Sesssion->Users, each User then has all laps with the session_id of 1 and the user_id is ignored.

After looking over this, I can lazy load the data as I want it. But could it be loaded with relationships?

$sessions = Session::whereIn('id', [1,2,3])->with(['users'])->get();

foreach ($sessions as $session) {
    foreach ($session->users as $user) {
        $driver->laps = SessionLap::where('session_id', $session->id)->where('user_id', $user->id)->get();
    }
}

Hi @RobTrehy,
Unfortunately, it's not possible to get this result with a relationship.

Thanks - I thought so once I took some time away and came back to it 🙂
