I have 4 tables:

User model
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Zizaco\Entrust\Traits\EntrustUserTrait;
class User extends Authenticatable
{
use Notifiable;
use EntrustUserTrait;
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
public function roles()
{
return $this->hasOne('App\Role', 'id', 'role_id');
}

Answer 1

In you Role model
Something like this you need to do (Many to Many)
//.......................
public function permissions()
{
return $this->belongsToMany('App\Permission','permission_role''role_id', 'permission_id');
}
//......................
See Many to Many relationship: Link
And to get the data into your controller
//..........................................
$user = get data with role and permission
$roles= $user->roles;
foreach($roles as $role){
foreach($role->permissions as $permission){
$permissiona_name = $permission->name;
}
}
//...........................
first check with var_dump($user)
Many to many with pivot (see Retrieving Intermediate Table Columns section)
return $this->belongsToMany('App\Role')->withPivot('column1', 'column2');
