How to generate a crud in cakephp 4, To create a crud in cakephp 4 it is necessary to add the following process

How to generate a crud in cakephp 4

First it is necessary to create a controller, for this example we will create a controller called Users, with the following command, which creates the resources type methods

bin/cake bake controller Users

Once the controller is created, we proceed to create the model and the table

bin/cake bake model Users

Then we will create the views, with their corresponding structure

bin/cake bake template Users

The above steps can be simplified with the following command


bin/cake bake all Users

Once the process is finished, a default structure will be created, in the templates/Users folder you will find the necessary files with a .php extension, which are the following

  • add.php
  • edit.php
  • index.php
  • view.php

Each of these files will extend the default Layout/default.php file.

Each of these views will be associated with a controller which will be called UsersController.php , and will have the following structure by default

 

declare(strict_types=1);

namespace App\Controller;

use Cake\Http\Exception\NotFoundException;

/**
 * Users Controller
 *
 * @property \App\Model\Table\UsersTable $Users
 * @method \App\Model\Entity\User[]|\Cake\Datasource\ResultSetInterface paginate($object = null, array $settings = [])
 */
class UsersController extends AppController
{   
    /**
     * Index method
     *
     * @return \Cake\Http\Response|null|void Renders view
     */
    public function index()
    {
        $users = $this->paginate($this->Users);

        $this->set(compact('users'));
    }

    /**
     * View method
     *
     * @param string|null $id User id.
     * @return \Cake\Http\Response|null|void Renders view
     * @throws \Cake\Datasource\Exception\RecordNotFoundException When record not found.
     */
    public function view($id = null)
    {
        $user = $this->Users->get($id, [
            'contain' => [],
        ]);

        $this->set(compact('user'));
    }

    /**
     * Add method
     *
     * @return \Cake\Http\Response|null|void Redirects on successful add, renders view otherwise.
     */
    public function add()
    {
        $user = $this->Users->newEmptyEntity();
        if ($this->request->is('post')) {
            $user = $this->Users->patchEntity($user, $this->request->getData());
            if ($this->Users->save($user)) {
                $this->Flash->success(__('The user has been saved.'));

                return $this->redirect(['action' => 'index']);
            }
            $this->Flash->error(__('The user could not be saved. Please, try again.'));
        }
        $this->set(compact('user'));
    }

    /**
     * Edit method
     *
     * @param string|null $id User id.
     * @return \Cake\Http\Response|null|void Redirects on successful edit, renders view otherwise.
     * @throws \Cake\Datasource\Exception\RecordNotFoundException When record not found.
     */
    public function edit($id = null)
    {
        $user = $this->Users->get($id, [
            'contain' => [],
        ]);
        if ($this->request->is(['patch', 'post', 'put'])) {
            $user = $this->Users->patchEntity($user, $this->request->getData());
            if ($this->Users->save($user)) {
                $this->Flash->success(__('The user has been saved.'));

                return $this->redirect(['action' => 'index']);
            }
            $this->Flash->error(__('The user could not be saved. Please, try again.'));
        }
        $this->set(compact('user'));
    }

    /**
     * Delete method
     *
     * @param string|null $id User id.
     * @return \Cake\Http\Response|null|void Redirects to index.
     * @throws \Cake\Datasource\Exception\RecordNotFoundException When record not found.
     */
    public function delete($id = null)
    {
        $this->request->allowMethod(['post', 'delete']);
        $user = $this->Users->get($id);
        if ($this->Users->delete($user)) {
            $this->Flash->success(__('The user has been deleted.'));
        } else {
            $this->Flash->error(__('The user could not be deleted. Please, try again.'));
        }

        return $this->redirect(['action' => 'index']);
    }      
   
}

And with these simple steps we have created a CRUD in a short time, something necessary that a cakephp framework developer should know
