Meta-Data directory cannot be written

Question

I am using Phalcon and MySQL. Upon logging in I received an error like this,

Meta-Data directory cannot be written
#0 [internal function]: Phalcon\Mvc\Model\MetaData\Files->write('map-map\\models\\...', Array)
#1 [internal function]: Phalcon\Mvc\Model\MetaData->_initialize(Object(Map\Models\Users), NULL, NULL, NULL)
#2 [internal function]: Phalcon\Mvc\Model\MetaData->readColumnMapIndex(Object(Map\Models\Users), 1)
#3 [internal function]: Phalcon\Mvc\Model\MetaData->getReverseColumnMap(Object(Map\Models\Users))

I have given access www-data as well as my user to /var/www/ directory using this command,

sudo chown -R www-data:www-data /var/www/

but still getting the same error. Anyone who encountered the same issue? Any help would be appreciated.

I had this same issue when I switched to Ubuntu. Here's how I solved it.

First, I realized that even after running a CHMod on my full project directory I always come across the write error for Meta-Data.

A portion of my DI code to configure Models Meta-Data:

$di -> set('modelsMetadata', function(){
    $metaData = new MetaDataAdapter([
        'metaDataDir'   => APP_PATH . '/cache/metaData/'
    ]);
    return $metaData;
});

Make sure the folder exists. Then using the Terminal, I do a cd command to my /app/cache/ folder. Once there, run: sudo chmod 755 metaData

Hope this helps...
