Am working on an application built using Laravel,, on the backend I have some eloquent Many to many relationship between 2 tables mainly roles and permissions respectively . There is also a pivot table called role_permission. I have created relationships in the models and in the controller am capturing the following values to create a permission: name, description , slug, role_id.
On the logic am storing name, description and slug in the permissions table while the role_id am storing in the pivot table (role_permission). This works fine. On the response am fetching all the permissions stored in the permission table and displaying back as a JSON object.
The problem is I want to fetch the role_id in the pivot table and append to each JSON object that was shown as a response.
Role Model
<?php
namespace Modules\API\Entities;
use Modules\API\Entities\Permission;
use Illuminate\Database\Eloquent\Model;
class Role extends Model
{
protected $fillable = ['name' , 'slug' , 'description'];
/**
* A role has more than one permission
*/
public function permissions(){
return $this->belongsToMany(Permission::class , 'role_permission');
}
}
Permission model
<?php
namespace Modules\API\Entities;
use Modules\API\Entities\Role;
use Illuminate\Database\Eloquent\Model;
class Permission extends Model
{
protected $fillable = ['name' , 'slug' , 'description'];
/**
* A permission has more than one role
*/
public function roles(){
return $this->belongsToMany(Role::class , 'role_permission');
}
}
Controller file (PermissionController.php)
<?php
namespace Modules\API\Http\Controllers;
use Carbon\Carbon;
use Modules\API\Common\helpers\GeneralHelper;
use Illuminate\Http\Request;
use Illuminate\Database\QueryException;
use Illuminate\Http\Response;
use Illuminate\Routing\Controller;
use Validator;
use Modules\API\Entities\Permission;
class PermissionController extends Controller
{
protected $requestTime;
protected $reference_number;
public function __construct()
{
$this->requestTime = Carbon::now()->toDateTimeString();
}
public function createPermission(Request $request) {
$validator = Validator::make($request->all(), [
'name' => 'required',
"slug" => 'required',
]);
if ($validator->fails()) {
$response = GeneralHelper::failureException("Validation Failed", $validator->errors()->all(), Carbon::now()->toDateTimeString());
}
else{
$name = $request->name;
$description = isset($request->description) ? $request->description : null;
$slug = isset($request->slug) ? $request->slug : null;
$role = isset($request->role_id) ? $request->role_id : null;
try{
$permission = new Permission;
$permission->name = $name;
$permission->slug = $slug;
$permission->description = $description;
$permission->save();
//Attach role to pivot table if permission is saved
if($permission->save() && !is_null($role)){
$permission->roles()->attach($role);
}
//Select specific columns from permissions table and return a JSON object
$permissions = Permission::select('id' , 'name', 'slug', 'description')->get()->toArray();
$response = response()->json(GeneralHelper::success("Permision Successfully added", "data", $permissions , Carbon::now()->toDateTimeString()));
} catch(QueryException $e){
$response = response()->json(GeneralHelper::failureException("Database Exception", $e->getMessage() . " at LINE " . $e->getLine(), Carbon::now()->toDateTimeString()), Response::HTTP_INTERNAL_SERVER_ERROR);
}
}
return $response;
}
}
Sample response in POSTMAN after the above logic
{
"request_time": "2019-09-03 07:54:54",
"response_time": "2019-09-03 07:54:54",
"status": "success",
"message": "Permision Successfully added",
"data": [
{
"id": 1,
"name": "Create Post",
"slug": "craete-post",
"description": "mnmnmn"
},
{
"id": 3,
"name": "delete User",
"slug": "del-user",
"description": "mnmnmn"
},
{
"id": 5,
"name": "Create User",
"slug": "create-user",
"description": "mnmnmn"
}
]
}
Updated response
{
"request_time": "2019-09-03 09:16:46",
"response_time": "2019-09-03 09:16:46",
"status": "success",
"message": "Permision Successfully added",
"data": [
{
"id": 1,
"name": "Kingston",
"slug": "kingston-red-iuy",
"description": "mnaskjas",
"roles": [
{
"id": 3,
"name": "Editor",
"slug": "editor",
"description": "Editor",
"created_at": "2019-09-02 06:37:08",
"updated_at": "2019-09-02 06:37:08",
"pivot": {
"permission_id": 9,
"role_id": 3
}
}
]
}
]
}`
After using this command in the logic :
$permissions = Permission::select('id' , 'name', 'slug', 'description')->with('roles')->get()->toArray();
