Laravel 5 Global CRUD Class

Before anyone asks, I looked at the generators CRUDand I know everything about resource routes Laravel, but that’s not quite what I am pulling for this.

I want to create one route with pair parameters and one global class that (uses / extends?) The model controller for simple operations CRUD. We have about 20 models and creating a resource Controllerfor each table would be more time-consuming than finding a way to create a global class CRUDto handle all calls like " api" and any request ajax json, for example, the create / update / destroy instruction.

So my question is, what is the cleanest and best way to structure a class to handle all the requests CRUDfor each Modelthat we have, without having to have a resource Controllerfor each Model? I tried to investigate this and cannot find any links, except for one, for generators CRUDand links describing laravel Resource route.

The easiest way is to do the following:

  • Add a route for your resource controller:

    Route::resource('crud', 'CrudController', array('except' => array('create', 'edit')));

  • Build your crud controller

    <?php namespace App\Http\Controllers;

use Illuminate\Routing\Controller;
use App\Models\User;
use App\Models\Product;
use Input;

class CrudController extends Controller
{
    const MODEL_KEY = 'model';

    protected $modelsMapping = [
        'user' => User::class,
        'product' => Product::class
    ];

    protected function getModel() {
        $modelKey = Input::get(static::MODEL_KEY);
        if (array_key_exists($modelKey, $this->modelsMapping)) {
            return $this->modelsMapping[$modelKey];
        }

        throw new \InvalidArgumentException('Invalid model');
    }

    public function index()
    {
        $model = $this->getModel();
        return $model::all();
    }

    public function store()
    {
        $model = $this->getModel();
        return $model::create(array_except(Input::all(), static::MODEL_KEY));
    }

    public function show($id)
    {
        $model = $this->getModel();
        return $model::findOrFail($id);
    }

    public function update($id)
    {
        $model = $this->getModel();
        $object = $model::findOrFail($id);
        return $object->update(array_except(Input::all(), static::MODEL_KEY));
    }

    public function destroy($id)
    {
        $model = $this->getModel();
        return $model::remove($id);
    }
}

  • :) model, - . . id = 5 do

    GET /crud/5?model=user

CrudController, :

    // Show either an empty form or a form
    // populated with the given model atts
    public function createOrEdit($model)
    {
        $classNameArray = explode('\\', get_class($model));

        $className = strtolower(array_pop($classNameArray));

        $view = view($className . '.form');

        $view->formAction = "$className/save";

        if(is_object($model) && $model->exists)
        {
            $view->model = $model;

            $view->formAction .= "/{$model->id}";
        }

        return $view;
    }

    public function save($model)
    {
        // Validation required so do it
        // Make sure each Model has $fillable specified
        return $this->model->fill($this->request)->save();
    }

    public function delete($model)
    {
        return $this->model->delete();
    }
}
