Hi,
I would like to shift the theme selection process to a Page in the CMS.
I have the following;

class Config extends Page {

   static $db = array(
      'Theme' => 'Text',
   );
   
   function get_current_theme() {
      $result = DataObject::get_one('Config');
      return $result->Theme;
   }
   
The function returns the value of Theme if I call $get_current_theme from a template but if I call it from mysite/_config.php using

Config::get_current_theme();

I get the following errors, which I assume are because I am ahead of the class construction of SS.

Warning: ClassInfo::dataClassesFor() no parents for Config in sapphire\core\ClassInfo.php on line 49

Warning: Invalid argument supplied for foreach() in sapphire\core\ClassInfo.php on line 50

Fatal error: DataObject::buildSQL: Can't find data classes (classes linked to tables) for Config in sapphire\core\model\DataObject.php on line 1334
Can I achieve the same DB query using the SQLQuery function? If so how, I can't work out the syntax from the doco or api pages.

Thanks for that.
I can get the get_current_theme() code to run, my issue is querying the Config table for the value of Theme.
At the very least what I want to do is "SELECT * FROM Config" and then get the value of Theme from the 1 row which is returned (as I only have one row..)

But how to do it from my Config.php class function without the errors listed on original post?
