So I have just gone through a update going from CI 2.0.4 to 3.1.4 and ran into the issue with Sparks now being redundant I've had to move onto composer to get php active record working..
however I have had autoloading issues/ Solved by including the model directly into the controller ie: require_once(APPPATH.'models/User.php');
But now im getting the following error..
An uncaught Exception was encountered
Type: ActiveRecord\DatabaseException
Message: Empty connection string
Filename: /var/www/html/vendor/php-activerecord/php-activerecord/lib/Connection.php
Line Number: 105
btw to load the composer autoload I've put: config['composer_autoload'] = '../vendor/autoload.php';
as the vendor directory sits outside the application folder in its parents folder.
Any help would be greatly appreciated..
You can move the vendor directory to your public_html/www and try
config['composer_autoload'] = FCPATH.'vendor/autoload.php';
