phql changed when executing using modelsManager - phalcon

Question

I'm new to Phalcon and would like to create a PHP web-service on my WAMP server. I have a table called "coreswings" in MySQL database and it represents the cores and wings of a large building. There are five fields: abbr, name, type, busyFrom, busyTo.
Following the tutorial on http://docs.phalconphp.com/en/latest/reference/tutorial-rest.html , I can route my requests to my desired functions, but the phql, "SELECT * FROM coreswings", doesn't work and returns me fatal errors.
index.php
<?php
/*###########################################################################
########## Set up connection to be used by model CoresWings, start ##########
###########################################################################*/
// use Loader() to autoload the model
$loader = new \Phalcon\Loader();
$loader->registerDirs(array(__DIR__.'/models/'))->register();
$di = new \Phalcon\DI\FactoryDefault();
// set up the database service
$di->set('db', function(){
return new \Phalcon\Db\Adapter\Pdo\Mysql(array(
"host" => "localhost",
"username" => "user",
"password" => "user_pw",
"dbname" => "map"
));
});
// create and bind the DI to the application
$app = new \Phalcon\Mvc\Micro($di);
/*#########################################################################
########## Set up connection to be used by model CoresWings, end ##########
#########################################################################*/
/*#########################################################
########## create routes according to api, start ##########
#########################################################*/
// get all cores and wings
$app->get('/coresWings', function() use ($app){
$phql = "SELECT * FROM coreswings";
$coresWings = $app->modelsManager->executeQuery($phql);
$data = array();
foreach($coresWings as $coreWing){
$data[] = array(
'abbr' => $coreWing->abbr,
'name' => $coreWing->name,
'type' => $coreWing->type,
'busyFrom' => $coreWing->busyFrom,
'busyTo' => $coreWing->busyTo,
);
}
echo json_encode($data);
});
// testing purpose
$app->get('/testing', function(){
$data = array(
'function' => 'tesing',
'data' => '001'
);
echo json_encode($data);
});
/*#######################################################
########## create routes according to api, end ##########
#######################################################*/
$app->handle();
?>
When I access the URL http://localhost/FYP/001/api/coresWings, the following errors are shown:
( ! ) Fatal error: Uncaught exception 'Phalcon\Mvc\Model\Exception' with message 'Table "cores_wings"
doesn't exist on database when dumping meta-data for CoresWings' in
D:\Program Files\wamp\www\FYP\001\api\index.php on line 39
( ! ) Phalcon\Mvc\Model\Exception: Table "cores_wings" doesn't exist on database when dumping meta-data for CoresWings in D:\Program Files\wamp\www\FYP\001\api\index.php on line 39
Of course I don't have a table called "cores_wings", but my phql is "SELECT * FROM coreswings". Please tell me if I have done anything wrong. Thanks so much.

Answer 1

If you want minimal configuration then you should follow some PhalconPHP's conventions.
One of them is that it for CamelCaseModel PhalconPHP uses camel_case table.
If you want to set different tabel for model then you should set it's source:
class CoresWings extends Model{
public function initialize() {
$this->setSource('coreswings');
}
}

Answer 2

You can use Phalcon\Mvc\Model::getSource() method. It is table name map with manual.
