我应该将哪些数据存储在Laravel 5中的会话变量中

Question

I am new to laravel. I have been working on a laravel 5 app with different types of users. I need information about which type of user is currently logged in different sections of my views:

Currently, I have been doing something like below on various controller methods and with the user object, I can determine which type of user it is in my view:

In Controller:

public function someMethod(){
    $user = Auth::user();
    return view('applications.show', compact('user'));
}

In View:

if($user->is_manager)
   // do this
else if($user->is_admin)
  // do that 

Because I need information about the user-type in various views, I have been calling Auth::user() in several places and I am beginning to think that this is adding some load on the DB. Is it better to store the user-type in a session variable and what kind of data should I be storing in my session?

Answer 1

It wouldn't be an issue storing it in the session.

In the is_manager function in your User class, you could do something like the following...

public function is_manager()
{
    // Check if the session has been set first.
    if(\Session::has('is_manager')) {
        return \Session::get('is_manager');
    }

    // Do your necessary logic to determine if the user is a manager, ex...
    $is_manager = $this->roles()->where('name', '=', 'manager')->count() == 1;

    // Drop it in the session
    \Session::put('is_manager', $is_manager);

    return $is_manager;
}

Keep in mind if your session driver is set to database, then this obviously isn't going to help.
