Relationship with Pivot Table Laravel's Eloquent and Inner Loops

Question

Ok, can anyone help me with this scenerio? I want to make a loop of Divisions and an inner loop of all the teams in that division using relationships in Eloquent. Been googling and expermenting but can't get the right results.

My tables are as such:

Divisions

division_id INT PK
division_name VARCHAR
...

Teams

team_id INT PK
team_name VARCHAR
...

division_team (pivot table)

id INT PK
division_id INT FK
team_id INT FK

My Models are as such: DivisionTeamPivot

class DivisionTeamPivot extends \Eloquent {
    protected $fillable = [];
    protected $table = 'division_team';

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

    public function division(){
        return $this->belongsTo('Division');
    }

Divisons

class Division extends \Eloquent {

    protected $primaryKey = 'division_id';
    public function teams(){
        return $this->hasMany('Team','division_team','division_id','team_id');
    }

}

Teams

class Team extends \Eloquent {

    protected $primaryKey  = 'team_id';
    public function division(){
        return $this->belongsTo('Division','division_team','team_id','division_id');
    }

}

My Controller has:

$divisions = DivisionTeamPivot::with('Team','Division')->get();

My View:

<section class="panel">
            <header class="panel-heading">
               <h5>{{$division->division->division_name}} Division {{$i}}</h5>
            </header>
            <table class="table">
                <thead>
                <tr>
                    <th></th>
                    <th>Team Name</th>
                    <th class="center">Total Points</th>
                    <th class="center">Rank</th>
                </tr>
                </thead>
                <tbody>
                @foreach($division->team as $team)
                <tr>
                    <td width="75"><img src="/img/logos/{{team->team_logo}}" width="50"></td>
                    <td><a href="/teams/details"> {{team->team_name}}</a></td>
                    <td class="center">1,345</td>
                    <td class="center">1</td>
                </tr>
                 @foreach
                </tbody>
            </table>
        </section>

What I want to do is loop over the divisions and then sub loop the teams that are in those divisions. I saw someone on here to make a pivot table model but when I use it, it loops over all the same divisions based off the division_id table in the pivot but I get the name. Its creating one team per duplicate division. I need them grouped based on the divisions they are in. And, actually, I still can't get the teams name to show. I also really want the eager loading to be working so I get the most efficient queries I can. Thanks!!

For making the many-to-many relationship you need to use belongsToMany instead of belongsTo in your both models (Division and Team) and you don't need to use another model as DivisionTeamPivot for pivot table. So in Division and Team use belongsToMany method:

// Division Model
public function teams(){
    return $this->belongsToMany('Team', 'division_team', 'division_id', 'team_id');
}

// Team Model
public function divisions(){
    return $this->belongsToMany('Division', 'division_team', 'team_id', 'division_id');
}

Make the query like this:

$divisions = Division::with('teams')->get();
return View::make('viewname')->with('dvisions', $divisions);

In the view the nested loops could be something like this:

@foreach($divisions as $division)
    {{ $division->division_name }}
    @foreach($division->teams as $team)
        {{ ... }}
        {{ $team->team_name }}
    @endforeach
@endforeach
