I was unable to rebuild my model after upgrading from phalcon 1.3.2 to 1.3.4 and the latest (master) devtool
This is the error I received
C:\wamp\www\myproject\application\myapp>phalcon all-models --relations --fk --validations --get-set --doc --force --namespace=Myapp\Models --extends=\Myapp\Library\ModelBase
Phalcon DevTools (1.3.4)
  Error: Unable to write to '.\public/C:\wamp\www\myproject\application\myapp\app\config/../../app/models\Admin.php'
I figured out it was going into a condition that I didn't need (i think) from the phalcon-dev-tools-master/scripts/Phalcon/commands/Builtin/AllModels.php line #86
       if (file_exists($path.'public')) {
            $modelsDir = 'public/'.$config->application->modelsDir;
        } else {
            $modelsDir = $config->application->modelsDir;
        }
After commenting the "public" part it resolved my issue:
        //            if (file_exists($path.'public')) {
        //                $modelsDir = 'public/'.$config->application->modelsDir;
        //            } else {
                          $modelsDir = $config->application->modelsDir;
        //            }
I also tried to specify the path with the --directory=s parameter but it did even worst
  Error: Unable to write to 'C:\wamp\www\myproject\application\myapp/\public/C:\wamp\www\myproject\application\myapp\app\config/../../app/models\Admin.php'
Am I missing something?
Thanks !
