Adding extra information to session, based on user role, just after successful authorization

I am new to Laravel and I need help to resolve the problem I am facing. In my Laravel 5.4 application, I have role based users. There are 4 types of role:

1. Admin
2. School_admin
3. Inspector
4. Committee_member

Following are my models (for their respective database tables): class Role extends Model { protected $fillable = [ 'name', 'description', ]; public function users(){ return $this->hasMany('App\User')->withTimeStamps(); } }

class User extends Authenticatable { use Notifiable; protected $fillable = [ 'name', 'uname', 'password', ]; protected $hidden = [ 'password', 'remember_token', ]; public function roles(){ return $this->belongsToMany('App\Role')->withTimestamps(); } }

Now I have a third table called “block_inspectors” that contains extra information about the inspectors. Users only with role “Inspector” will have entries in this table. Other users will not have any records in this table.

Block_inspectors table fields:

1. Id (primary key)
2. User_id (foreign key mapping to the id column of users table)
3. Designation
4. Block_id

My Query: How do I fetch the extra information from the block_inspectors table once I know the logged in user has a role “Inspector”? I would like to keep this fetched information in the session so that I can use them in other controllers / views as and when required Currently I am using default Laravel Authentication system. It would be great if this can be achieved with minimum changes to the default login system.
