    */
    'providers' => [

        'ChatProvider'

    ],

    'debug' => true,

];

and in providers/ChatProvider.php

<?php

use Vinelab\Minion\Provider;

class ChatProvider extends Provider {

    protected $prefix = 'order.';

    public function boot()
    {
        // will be registered to topic: chat.send
        $this->register('send', 'sendMessage');
    }

    public function sendMessage($args, $data)
    {
        $message = $data->message;

        // store message in the database

        // tell everyone about it
        $this->publish('message', compact('message'));

        // response with the status
        return true;
    }
    }
}

I check for various name space and lot of things but i can not solve this.

Please tell where i am wrong.

Thanks...

What version of Laravel are you using ?

[Mulkave]

Ah, I see from your structure it seems to be Laravel 4. can you please use the following in your composer.json:

{
   "vinelab/minion": "1.2"
}

then perform a composer update and try again.

[arjundas]

NO, its not work, :(,

I am using modular structure in Laravel, Can it affect this?

I am using creolab/laravel-modules for Modularization in laravel.

[Mulkave]

It shouldn't matter what structure you use, as long as your provider is extending Vinelab\Minion\Provider it should work.

If you are running minion using artisan make sure you tell minion about your ChatProvider class with the register option:

php artisan minion:run --register="ChatProvider"

[arjundas]

I tried this also but it still not working.

[Mulkave]

seems like Minion is detecting the wrong ChatProvider class

[ChaosPower]

@arjundas I replied to your stackoverflow. @Mulkave is right, it is detecting a different ChatProvider class. Make sure Laravel is loading providers folder or you can't just use ChatProvider directly. You need to specify proper namespacing. PSR-0 standard.

namespace Providers\ChatProvider;

then you register ChatProvider like this --register"Providers\ChatProvider" you need to specify composer what to autoload.

Minion and Laravel are loading differently. That's why you need to specify a namespace.

Just got the same error. I am using Laravel 4. Here is my folder configuration :

app
    + Arato
        + push
            - AlertProvider.php
    + commands
    + config
    + controllers

in my composer.json :

"autoload": {
    "classmap": [
        ...
        "app/Arato"
    ]
}

the minion.php :

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Router Realm
    |--------------------------------------------------------------------------
    |
    | The realm that the router should use.
    |
    */
    'realm'     => 'minion',

    /*
    |--------------------------------------------------------------------------
    | Router Host
    |--------------------------------------------------------------------------
    |
    | The IP or hostname that the router should run under.
    |
    */
    'host'      => '127.0.0.1',

    /*
    |--------------------------------------------------------------------------
    | Router Port
    |--------------------------------------------------------------------------
    |
    | The port that should be used by the router.
    |
    */
    'port'      => 9090,

    /*
    |--------------------------------------------------------------------------
    | Auto-registered Providers
    |--------------------------------------------------------------------------
    |

    | session start of the router, in return their role is to register RPCs,
    | subscribe and publish to topics and pretty much whatever an Internal Client does.
    |
    */
    'providers' => [
        "Arato\push\AlertProvider"
    ],

    'debug'     => true,

];

the AlertProvider.php file :

<?php
namespace Arato\push;

use Vinelab\Minion\Provider;

class AlertProvider extends Provider
{
    public function boot()
    {
        $this->publish('i.am.here', ['name' => 'mr.minion']);
    }
}

I do not know why the namespace is incorrect.

Best regards.

[Mulkave]

The problem is a namespace problem, you are classmapping in composer instead of autoloading with PSR, try:

"autoload": {
   " ...",
   "psr-0": {
       "Arato": "app/"
    }
}

And as a standard convention, try uppercasing the push folder, namespace and provider such as:

namespace Arato\Push;

Thank you, I think it should be fixed now.

However I still have a problem, when I run php artisan minion:run with debug to true, I get the following :

and it is looping.

EDIT : seems this behavior comes from $this->publish('i.am.here', ['name' => 'mr.minion']); EDIT 2 :

it should be

$this->publish('i.am.here', [], ['name' => 'mr.minion']);

[Mulkave]

@prbaron exactly! It is publish($topic, $args, $kwArgs) where $args is an array of arguments and $kwArgs is the key-value array. Glad you had it resolved.
