Controller does not define Model object

Need Help
1

Dear all,

I am quite New to CakePHP, especially version 4.x.

I created Migrations and run migrate to create my DB tables, then I use bake to generate all the scaffolding files.

I have users and user_groups tables. users table has user_group_id foreign key.

Whenever i go to <app_root>/usergroups/ , or any actions of UserGroupsController , debug says:

[ Notice (1024)]: Undefined property: UserGroupsController::$UserGroups

I am stuck at this, I have read again convention, but everything seem to be fine. What did I do wrong?
I have wrote an app in CakePHP 3x before, so the concept of CakePHP is not too new to me, but obviously there is something wrong with my code.

I am currently have mental block because of this in last few days. Please someone point me out of this.
Thank you very much.

Could you post your UserGroupsController code here?

Firstly thank you Mr. dakota for your kind and quick response.

Please see my UserGroupsController code below.

I have generated code in CakePHP 3.8 using bake, and the code works fine if I access with URL like <app_root>/user_groups/* and failed as above question if accessed with URL <app_root>/usergroups/* .

Tried again <app_root>/user_groups/* with CakePHP 4.0.1 , it says Cake\Http\Exception\MissingControllerException

Documentation said that we can access it either way (ver 3.x doc), but seem only the way with underscore works (in ver 3.x only). Is it a bug?

<?php
declare(strict_types=1);
namespace App\Controller;

class UserGroupsController extends AppController
{


    public function index()
    {
        $this->paginate = [
            //'contain' => ['Leaders', 'UpperGroups'],
        ];
        $userGroups = $this->paginate($this->UserGroups);

        $this->set('UGController', compact($this));
        $this->set(compact('userGroups'));
    }

   
    public function view($id = null)
    {
        $userGroup = $this->UserGroups->get($id, [
            'contain' => ['Leaders', 'UpperGroups', 'Users'],
        ]);

        $this->set('userGroup', $userGroup);
    }

   
    public function add()
    {
        $userGroup = $this->UserGroups->newEmptyEntity();
        if ($this->request->is('post')) {
            $userGroup = $this->UserGroups->patchEntity($userGroup, $this->request->getData());
            if ($this->UserGroups->save($userGroup)) {
                $this->Flash->success(__('The user group has been saved.'));

                return $this->redirect(['action' => 'index']);
            }
            $this->Flash->error(__('The user group could not be saved. Please, try again.'));
        }
        $leaders = $this->UserGroups->Leaders->find('list', ['limit' => 200]);
        $upperGroups = $this->UserGroups->UpperGroups->find('list', ['limit' => 200]);
        $this->set(compact('userGroup', 'leaders', 'upperGroups'));
    }

    
    public function edit($id = null)
    {
        $userGroup = $this->UserGroups->get($id, [
            'contain' => [],
        ]);
        if ($this->request->is(['patch', 'post', 'put'])) {
            $userGroup = $this->UserGroups->patchEntity($userGroup, $this->request->getData());
            if ($this->UserGroups->save($userGroup)) {
                $this->Flash->success(__('The user group has been saved.'));

                return $this->redirect(['action' => 'index']);
            }
            $this->Flash->error(__('The user group could not be saved. Please, try again.'));
        }
        $leaders = $this->UserGroups->Leaders->find('list', ['limit' => 200]);
        $upperGroups = $this->UserGroups->UpperGroups->find('list', ['limit' => 200]);
        $this->set(compact('userGroup', 'leaders', 'upperGroups'));
    }

    
    public function delete($id = null)
    {
        $this->request->allowMethod(['post', 'delete']);
        $userGroup = $this->UserGroups->get($id);
        if ($this->UserGroups->delete($userGroup)) {
            $this->Flash->success(__('The user group has been deleted.'));
        } else {
            $this->Flash->error(__('The user group could not be deleted. Please, try again.'));
        }

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

Ah, I see the issue. CakePHP 4 changed the default routing to be dashed instead of underscored, so the correct url would be /user-groups.

It depends on your router configuration.
