Hi!

I'm facing a problem with a belongsToMany relationsship on a custom pivot model I cannot solve. My custom Model works. I have a Game model, a Team model and a custom GameTeam model for the pivot table. Now I have an additional Bet model which has a belongsToMany relationship to the GameTeam model and the custom GameTeam model should also have a belongsToMany relationship to the Bet model. So there is another pivot table between GameTeam and Bet.

I always get the following error if I want to call $bet->gameTeams

Error: Argument 1 passed to Illuminate\Database\Eloquent\Relations\Pivot::__construct() must be an instance of Illuminate\Database\Eloquent\Model, none given

Here is my code:

Game Model

class Game extends Eloquent {

public function teams() {
	return $this -> belongsToMany('Team', 'game_team', 'game_id', 'team_id') -> withPivot('id','goals', 'approved');
}

public function newPivot(Eloquent $parent, array $attributes, $table, $exists) {
	if ($parent instanceof Team) {
		return new GameTeam($parent, $attributes, $table, $exists);
	}
	return parent::newPivot($parent, $attributes, $table, $exists);
}

}

Team model

class Team extends Eloquent {

public function games() {
	return $this -> belongsToMany('Game', 'game_team', 'team_id', 'game_id') -> withPivot('id','goals', 'approved');
}

public function newPivot(Eloquent $parent, array $attributes, $table, $exists) {
	if ($parent instanceof Game) {
		return new GameTeam($parent, $attributes, $table, $exists);
	}
	return parent::newPivot($parent, $attributes, $table, $exists);
}

}

GameTeam custom pivot model

class GameTeam extends Pivot {

protected $table = 'game_team';

public function team() {
	return $this -> belongsTo('Team');
}

public function game() {
	return $this -> belongsTo('Game');
}

public function bets() {
	return $this -> belongsToMany('Bet', 'game_team_bet', 'game_team_id', 'bet_id')-> withPivot('goals');
}

}

Bet model

class Bet extends Eloquent {

public function gameTeams() {
	return $this -> belongsToMany('GameTeam', 'game_team_bet', 'bet_id', 'game_team_id')-> withPivot('goals');
}

}
