Laravel 5.3 : eager load with many to many relationship - eloquent

Question

I'm trying to use eloquent to retrieve 5 last messages and display them on the dashboard.
The problem is, I need to get those messages depending on the user->role. But the message is linked to an update log. This update log is use to dispatch every dashboard message, sms to notify and email.
There is how it work :
User
public function role()
{
return $this->belongsTo(Role::class);
}
Role
public function updatelogs()
{
return $this->belongsToMany(Updatelog::class, 'role_updatelog');
}
public function users()
{
return $this->hasMany(User::class);
}
Updatelog
public function roles()
{
return $this->belongsToMany(Role::class, 'role_updatelog');
}
public function dashboard_message()
{
return $this->hasOne(DashboardMessage::class);
}
DashboardMessage
public function updatelog()
{
return $this->belongsTo(Updatelog::class);
}
There is what I tried:
$dashmessages = DashboardMessage::with(array('updatelog' => function($q) use($user) {
$q->with(array('roles' => function($q2) use($user) {
$q2->whereHas($user->role_id);
}));
$q->whereHas('institution');
}))->with('updatelog.institution.rate_grids')->orderBy('updated_at', 'DESC')->take(5)->get();
I'm getting the last 5 DashboardMessages without the role constraint. What am I doing wrong?
EDIT---------------------------------------------------
I just tried something else and it work perfectly:
$updatelog = Updatelog::whereHas('roles', function ($query) use($user) {
$query->where('role_id', $user->role_id);
})
->whereHas('dashboard_message')
->with('dashboard_message')
->whereHas('institution')
->with('institution')
->with('rate_grid')
->take(5)->get();
