navruzm / laravel-mongo-cache Goto Github PK

So I tried to use your mongo cache, i installed it everything, but I kept getting error and run your phpunit test, fortunately I was able to fix it. But anywhere here is error

$ vendor/bin/phpunit
PHPUnit 3.7.21 by Sebastian Bergmann.

Configuration read from /var/www/phpunit.xml

PHP Fatal error:  Class MongoCache\MongoStore contains 1 abstract 
method and must therefore be declared abstract or implement the remaining 
methods (Illuminate\Cache\StoreInterface::getPrefix) in 
/var/www/vendor/navruzm/laravel-mongo-cache/src/MongoCache/MongoStore.php 
on line 213
PHP Stack trace:

I got this when I called to Cach::get() like this

$value = Cache::get('key');

I fixed it by adding public function getPrefix() { } to MongoStore.php maybe someone else will have this same issue, this may fix it?!. Or am I doing something wrong?
And one more question is ok to use this driver in production??
