**Your software**  
My Mautic version is: 2.15.2  
My PHP version is: PHP 7.2.19-0ubuntu0.18.04.2 (cli) (built: Aug 12 2019 19:34:28) ( NTS )

**Your problem**  
My problem is: I have created a mautic hello world plugin based on mautic doc but i am unable to see the in database

These errors are showing in the log:

Steps I have tried to fix the problem:

1. Copied existing plugin and renamed in plugin dir to see if it shows (Failed)

2. Download sample plugin from internet (failed)  
[https://github.com/vishal-px/Mautic-Simple-Plugin](https://github.com/vishal-px/Mautic-Simple-Plugin)

3. Created a mautic plugin based on doc and run following command :  
php app/console cache:warmup --env=prod --no-debug  
php app/console mautic:plugins:reload

But i am not able to see the plugin. please tell me the steps i may be missing.

I have tried one of sample plugins and it seems to work and using that i have tried to create a sample plugin but i am getting an error. I have check the log and got below due which it seemed the plugin was not showing

mautic.CRITICAL: Uncaught PHP Exception InvalidArgumentException: “mautic.helloworld.model.contact is not a registered container key.” at /app/app/bundles/CoreBundle/Factory/ModelFactory.php line 58 {“exception”:"[object] (InvalidArgumentException(code: 0): mautic.helloworld.model.contact is not a registered container key. at /app/app/bundles/CoreBundle/Factory/ModelFactory.php:58)"}

In config i have set the following 🙂  
‘services’ =\> array(  
‘models’ =\> [  
‘mautic.helloworld.model.contact’ =\> [  
‘class’ =\> \MauticPlugin\MauticHelloWorldBundle\Model\ContactModel::class  
],  
],  
),

Hey,

Found the problem solved it based on doc is was extending CommonModel but the new mautic requires extending FormModel.
