Aura\Di error I can't figure out

[Chris Johnson]

I'm getting this error message:

Aura\Di\Exception\MissingParam: Param missing: \Clx\Api\X12ApiAction::$log

Yet I cannot tell how the parameter is missing.  What am I missing here?

Here's my container configuration:

public function define(Container $di)
{
    $di->params[X12ApiAction::class] = [
        'log' => $di->lazyNew(ClxMsg::class),
    ];
}

And here's my class constructor:

class X12ApiAction extends Action
{
    /**
     * @var ClxMsg
     */
    protected $log;

    /**
     * @param ClxMsg $log
     */
    public function __construct(ClxMsg $log)
    {

Looks like the problem with namespace.

Can you explicitly add 

$di->params['Clx\Api\X12ApiAction'] = [ 

    'log' => $di->lazyNew('Clx\Api\ClxMsg'), 

];

I have came across something when your namespace is using `use` and without use.

Eg :

$di->params[X12ApiAction::class] = [ 

    'log' => $di->lazyNew(ClxMsg::class), 

];

class X12ApiAction extends Action
{
    /**
     * @var ClxMsg
     */
    protected $log;

    /**
     * @param ClxMsg $log
     */

    public function __construct(\Clx\Api\ClxMsg $log)
    {

The `\Clx\Api\ClxMsg` and `Clx\Api\ClxMsg` are interpreted differently in params.

Hope that helps.

Hello Hari,

Thanks much for the reply.  I've tried many combinations of explicitly providing the namespaces, and I still get the same error.  The correct, full namespaces are actually:

\Clx\Api\X12ApiAction
\Clx\ClxMsg

I've got use statements in all involved files to alias them to just the class names.  But even when I spell out the full namespace, it fails.  I feel like I am overlooking some very simple and basic, but just cannot find it.

Regards,

..chris

Ah, it was a namespace resolution problem.  PHP is unpredictable this way.  Maybe Aura\Di should have some fuzzy logic built to handle these kinds of cases?

This works:

$di->params['\Clx\Api\X12ApiAction'] = [

    'log' => $di->lazyNew(\Clx\ClxMsg::class),
];

This does not work, even though it should be equivalent:

$di->params['Clx\Api\X12ApiAction'] = [

    'log' => $di->lazyNew(\Clx\ClxMsg::class),
];

This also fails, which is also the same as above:

$di->params[\Clx\Api\X12ApiAction::class] = [
    'log' => $di->lazyNew(\Clx\ClxMsg::class),
];

Look at this small test program:

<?php
namespace bar;
class Baz {}


echo \bar\Baz::class . PHP_EOL;
?>

This outputs:  bar\Baz with no leading \.

Based on your tests (and not on anything else, since I haven't used Aura yet), this should work too btw:

$di->params['\' . \Clx\Api\X12ApiAction::class] = [

    'log' => $di->lazyNew(\Clx\ClxMsg::class),
];

Happy to know this works for you :-) .
