Call to a Member Function find() on a non-object

Question

I’ve been racking my brain here for a while and I still don’t understand the mistake. I’m learning about Cakephp. I did the Regionals table MVC manually, and for the others, I used the Bake. The problem is that when I try to add a new congregation, this title error is returned. I’ve searched elsewhere, but I haven’t found a solution yet.

Grateful for any help.

It would be useful to have more information about the mistake to point you in a direction. Initially you are trying to call a method a variable that is not an object... To try to help you, if you are using apache, think about activating the Xdebug mod, it will give you more information about the error.

Xampp for windows:

Add these lines to your php.ini:

[XDebug]
zend_extension = "C:\xampp\php\ext\php_xdebug.dll"
xdebug.cli_color = 1
xdebug.var_display_max_children = -1
xdebug.var_display_max_depth = -1
xdebug.var_display_max_data = -1

In apache / linux:

Installation:

\# pecl install xdebug

Lines to add in php.ini

[XDebug]
zend_extension="/usr/local/php/modules/xdebug.so"
xdebug.cli_color = 1
xdebug.var_display_max_children = -1
xdebug.var_display_max_depth = -1
xdebug.var_display_max_data = -1

More information about Xdebug:

http://xdebug.org/docs/install

Put in the detail of the mistake and see if I can help you more.

Answer 2

I found the problem.

In Congregacaoscontroller.php, line 58, it looks like this:

$regionals = $this->Congregacao->Regional->find('list');

So I consulted my model Congregacao.php, and there it is, on line 46:

public $belongsTo = array(
        'Regionals' => array(
            'className' => 'Regionals',
            'foreignKey' => 'regionals_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        )
    );

That is, the correct is "Regionals", not "Regional". It was only correct in the controller and the add started to work normally.

$regionals = $this->Congregacao->Regionals->find('list', array(
            'fields' => array('id', 'descricao_regionals')
        ));
