Hi ItsRD , assuming that you have owner as a boolean in your migration here is what you have to do.

Project Model

 public function users()
{
    return $this->belongsToMany('App\User')->withPivot('owner');
}

withPivot lets you define others columns apart from the ids of the relationship. Documentation in the section: Retrieving Intermediate Table Columns

User Model

 public function projects()
{
    return $this->belongsToMany('App\Project')->withPivot('owner');
}

The same here.

Attaching Example

Route::get('attach',function (){

    $user = App\User::find(1);
    $user->projects()->attach(1,['owner'=> true]);
    $user->projects()->attach(3,['owner'=> false]);

    $user = App\User::find(2);
    $user->projects()->attach(3,['owner'=> true]);
});

I just create a database seeder with three projects and two users and use the route for attaching. Do it as you like it.

Project Item Blade

<h1>Name: {{ $project->name }}</h1>  
<p>Users: </p>
@foreach($project->users as $user)
<li>{{$user->name}} Owner: {{ $user->pivot->owner }}</li>
@endforeach

Output
