How to insert multiple role in employee table using laravel - php

Question

I'm building API and I'm struggling with store data for multiple employee roles, how to store, could you provide me some example,
sorry for using the foreign language.
Karyawan=employee,
Jabatan=role
Karyawan.php
public function jabatan() {
return $this->hasMany('\App\Jabatan','id_jabatan');
}
Jabatan.php
public function karyawan(){
return $this->belongsTo('\App\Karyawan','id_jabatan');
}
how to KaryawanController at store function should be...
this is my model and controller
i created my pivot table and i got this error
SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'field list' (SQL: insert into tb_jabatan_karyawan (id_jabatan, id_karyawan, 0, 1) values (0, 57, 1, 2))
ini controller sama modelnya..

Answer 1

I am using User and Role instead of Karyawan and Jabatan respectively (sorry for that). User and Role has Many-to-Many relation because one User may have multiple Roles and vice versa.
roles Table
+----+------+-----------+
| id | role | timeStamps|
+----+------+-----------+
role_user Pivot Table
+----+---------+---------+
| id | user_id | role_id |
+----+---------+---------+
Role Model
public function users(){
return $this->belongsToMany('App\User');
}
User Model
public function roles(){
return $this->belongsToMany('App\Role');
}
RoleUser Pivot
namespace App;
use Illuminate\Database\Eloquent\Relations\Pivot;
class RoleUser extends Pivot
{
protected $table='role_user';
protected $fillable = [
'user_id','role_id'
];
public static $role_attach_rules = [
'roles' => 'required|array|min:1|exists:roles,id'
];
public function user(){
return $this->hasOne('App\User', 'id', 'user_id');
}
public function role(){
return $this->hasOne('App\Role', 'id', 'user_id');
}
}
Controller Code for Assigning Roles to the User
Here you will understand the methods by their names.
public function getAssignRole(){
$users = User::all();
$roles=Role::all();
return View::make('assignrole', compact('users', 'roles'));
}
public function postAssignRole(Request $request){
$attachvalidator = Validator::make($request->all(),RoleUser::$role_attach_rules);
if ($attachvalidator->fails()){
return Redirect::back()->withErrors($attachvalidator)->withInput();
}
$user=$request->get('user');
$role=$request->get('roles');
$attach = User::find($user)->roles()->attach($role);
return 'Success';
}
public function detachRole(Request $request){
$user=$request->get('user_update');
$role=$request->get('roles_update');
$attach = User::find($user)->roles()->detach($role);
return 'detach Success';
}
View file (assignrole.blade.php) for Assigning Roles
//This form is for assigning roles
<form method="post" action="{{route('role.assignrole.post')}}">
{{csrf_field()}}
<select id="user" name="user" class="select_with_style" required>
#foreach($users as $user)
<option value="{{$user['id']}}">{{$user['name']}}</option>
#endforeach
</select>
<select id="roles" name="roles[]" class="select_with_style" multiple="" required>
#foreach($roles as $role)
<option value="{{$role['id']}}">{{$role['role']}}</option>
#endforeach
</select>
<br>
<input type="submit" name="submit" class="submit action-button" value="Submit"/>
</form>
//This is for detaching roles from user
<form method="post" action="{{route('role.detach')}}">
{{csrf_field()}}
<select id="user_update" name="user_update" class="select_with_style" required>
#foreach($users as $user)
<option value="{{$user['id']}}">{{$user['name']}}</option>
#endforeach
</select>
<select id="roles_update" name="roles_update[]" class="select_with_style" multiple="" required>
#foreach($roles as $role)
<option value="{{$role['id']}}">{{$role['role']}}</option>
#endforeach
</select>
<br>
<input type="submit" name="submit" class="submit action-button" value="Update"/>
</form>
Routes
Route::get('role/assignrole', array('as' => 'role.assignrole', 'uses' => 'YourController#getAssignRole'));
Route::post('role/assignrole', array('as' => 'role.assignrole.post', 'uses' => 'YourController#postAssignrole'));
Route::post('role/detach', array('as' => 'role.detach', 'uses' => 'YourController#detachRole'));
Hope this helps.
Edit
You can use Voyager instead of doing this much work. It is very easy to understand and well structured and I think you will love it.
