Laravel 4 tables relationship Eloquent

I have four tables:

Users: id, username
Roles: id, name
Domains id, title
DomainsAssignedRolesUsers id, role_id, user_id, domain_id

I want to get all user roles for a domain.

I do: 

User::find(1)->domains->first()->roles

But i get all domains roles, not only for my user. Help me to get user roles only for the selected domain/

My relations:

// User model:

public function rolesDomain() {
    return $this->belongsToMany('Role', 'domainsAssignedRolesUsers', 'user_id', 'role_id');
}

public function domains() {
    return $this->belongsToMany('Domain', 'domainsAssignedRolesUsers');
}

// Role model:

public function domains() {
    return $this->belongsToMany('Domain', 'domainsAssignedRolesUsers');
}

// Domain model:

public function roles() {
    return $this->belongsToMany('Role', 'domainsAssignedRolesUsers', 'domain_id', 'role_id');
}

public function users() {
        return $this->belongsToMany('User', 'domainsAssignedRolesUsers', 'domain_id', 'user_id');
    }

You want to get all the roles, from a specific domain, in relation with an user?

So this should do the trick:

User::find(1)->rolesDomain()->where('domain_id', $specificID)->get()

But if you want to only get the roles from the first domain for an user.

User::find(1)->domains()->first()->roles()->get();

And if you only want to retrieve the roles for a user.

User::find(1)->rolesDomain()->get()

And if you only want to retrieve all the roles from each domain in relation with an user.

User::find(1)->domains()->with('roles')->get()

Even if Eloquent documentation has a few example, This orm is really intuitive.

Check out Eloquent Triple Pivot (also on Packagist), it sounds like it does exactly what you want.

You'd set up your Models as User, Domain and Role (a User has many Domains and can have a Role in each). Then look at the docs on the Github page (particularly step 6), and you'd define this on your Domain model:

class Domain extends Eloquent {
    ...
    public function getRolesAttribute() {
        return $this->getThirdAttribute();
    }
}

Then you can simply call

$user = User::find(1);

$domain = $user->domains->first();
// or
$domain = $user->domains->find(73);

$roles = $domain->roles;

// Or the above can be condensed into just...
$roles = User::findOrFail( 1 )
             ->domains()
             ->findOrFail( 73 )
             ->roles;
