No value for key "item" found

[kdim95]

Laravel framework version: 9.26.1
Aimeos Laravel version: * 2022.07.2
PHP Version: 8.1.9
Environment: Linux

Following the example here, I created a decorator named "Mydecorator" inside
<MY PLUGIN>/src/Admin/JQAdm/Common/Decorator/Mydecorator.php
https://aimeos.org/docs/latest/admin/jq ... nd-panels/

I overrode the save() method like in the example:

Code: Select all

public function save() : ?string
{
	$item = $this->view()->item;
	// notifiy the 3rd party system
	return $this->getClient()->save();
}

I configured <MY PLUGIN>/config/admin.php like this:

Code: Select all

return [
	'jqadm' => [
		'product' => [
			'decorators' => [
				'global' => [ 'Mydecorator' ]
			]
		]
	],
	'jsonadm' => [
	],
];

When attempting to test saving the product, I get the following error:
"No value for key 'item' found"

The error occurs on this line:
$item = $this->view()->item;

I want to implement an audit log for tracking who changed what in every module.
I have tried the package "owen-it/laravel-auditing", but it does not work, as Aimeos does not use Eloquent models.

Help would be appreciated, thank you.

This is a mistake in the docs. Can you please try this instead:

Code: Select all

    public function save() : ?string
    {
        $result = $this->getClient()->save();
        $item = $this->view()->item; // assigned by inner objects
        // notify the 3rd party system
        return $result;
    }

Thank you, this removes the error, but there is another problem.

Now that this line is above everything, I can't reach the state of the item before the change.
$result = $this->getClient()->save();

After save() is called, the item is already changed, right?
How can I get the attributes of the item before the actual change?

You can only get the POST parameters using "$this->view()->param()" or "$this->view()->param( '<name>' )" but not set them and the item is assigned by the inner object so the options are limited for your use case.

Thank you, the best thing I can think of is:
1) Getting the product ID from the $_POST parameters
2) Querying the product to get the original values
3) While we are at it with the $_POST parameters, get the new values as well
4) Save the previous and changed values as JSONs in the database
4) Execute $this->getClient()->save();

I don't know how practical of a solution this is, I thought I could find a cleaner solution in the docs, thank you.

The Changelog manager decorator in the aimeos-core package is much better suited for that:

You can create your own decorator that does something similar.
