CakePHP controller method: unable to invoke it

Question

I've follow tutorial for CakePHP and i've generate a controller, a view, and a model for one database table. I've also implemented the add method for insert new values inside database, and everything works. Now, i've try to use cake bake to do the same thing, and after auto genereate controller with basic crud methods, i'm still not able to do add rows. This is the generated code:

class Admin extends AppModel {

/**
 * Primary key field
 *
 * @var string
 */
public $primaryKey = 'username';

/**
 * Display field
 *
 * @var string
 */
public $displayField = 'username';

/**
 * Validation rules
 *
 * @var array
 */
public $validate = array(
    'username' => array(
        'notEmpty' => array(
            'rule' => array('notEmpty'),
            'message' => 'insert username',
            'allowEmpty' => false
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'alphaNumeric' => array(
            'rule' => array('alphaNumeric'),
        //'message' => 'too long',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'isUnique' => array(
            'rule' => 'isUnique',
            'message' => 'This username has already been taken.'
        ),
        'maxLength' => array(
            'rule' => array('maxLength', 50),
            'message' => 'too long',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
    ),
    'password' => array(
        'notEmpty' => array(
            'rule' => array('notEmpty'),
            'message' => 'insert password',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'alphaNumeric' => array(
            'rule' => array('alphaNumeric'),
        //'message' => 'Your custom message here',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'maxLength' => array(
            'rule' => array('maxLength', 50),
            'message' => 'max lenght',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
    ),
);
}

}

and this is simple add View:

echo $this->Form->create(array('type' => 'post'));
echo $this->Form->input('username', array('label' => 'username', 'type' => 'text'));
echo $this->Form->input('password');
echo $this->Form->end('Save admin');

now, when i try to invoke

/admin/add

for show input form, i obtain this error message:

Error: AdminAddController could not be found. Error: Create the class AddController below in file: app\Controller\AddController.php

what's wrong?

Answer 1

In cakephp always Controller name are plural , Model name is singular and database table name are plural for example your table is admins & the Model name must be Admin. controller name AdminsController with camel caps and at the End of Admins, Controller must be added because AdminsController are inherit the properties of AppController class you should write this in your controller

class AdminsController extends AppController {
/* your action */
}

and your address bar

/Admins/add

Answer 2

You should Always make controller name plural like :

AdminsController

And call like /admins/add . This is basic cakePHP steps. Read cakePHP cook book.
