CakePHP在同一Controller的非对象上调用成员函数create（）

Question

Okay this is really odd I have the following test_sign_up action:

  public function test_sign_up(){

    if($this->request->is('post')){
        $signup_result = $this->request->data;

        $userData = array('User' => array(
            'username' =>$signup_result['User']['username'],
            'password'=> $signup_result['User']['password'],
            'group_id' => 2,
            'client_id' => 9999));

        $this->User->create();
    if ($this->User->saveAll($userData)) {
        $this->Session->setFlash(__('The user has been saved'));
        $this->redirect(array('action' => 'index'));
    } else {
        $this->Session->setFlash(__('The user could not be saved. Please, try again.'));
    }

    }

}

Now when I try to save a user I get:

 Call to a member function create() on a non-object 

Note that this function is within my UsersController

update

If I do:

$this->loadModel('User');

It works no problem, But should that be necessary when i'm already in the controller bound to the User model?

Answer 1

If you have a $uses array in your controller, then the controller will load these as models upon instantiation. For example:

<?php
class UsersController extends AppController {

    public $uses = array(
        'Client',
        'Website',
        'Category',
        'Type',
        'WebsiteIssue'
    );
}

In the above, the Users controller will only load the five models specified. If you want the User model to be instantiated too (as it would by default if $uses was not specified) then simply add 'User' to your $uses array as well.

Answer 2

Use $this->Form->create() instead of $form->create() .

You must use $this before helper object.

Your index.php code should looks like:

echo $this->Form->create("Contact");
