DataMapper ORM v1.8.2

[eluser]WanWizard[/eluser]
I hate annotations. And I'm not going to implement code that will parse PHP code to figure out what to do. In an ORM, you need every CPU cycle you can find to keep the performance acceptable.

Datamapper is (contrary to what the name implies) based on the active record pattern, in which the code follows the data store. So the data store (in this case the database table) is leading, Datamapper will use it's definition as-is.

If you want a mechanism to document database structure, and have the option to maintain different versions and migrate between them, I can recommend Phil Sturgeon's excellent Migrations library, which does just that.

As to your issue, it looks like something has changed in the form validation library. The language file is now only loaded when form validation is run. Which never happens with Datamapper, it uses it's own method to run rules. So loading the library no longer means the language file is loaded too.

To fix this, look in the Datamapper library for the __get() method. Find in there the section that loads the form validation library, and replace it by this:

Code:

// Special case to get form_validation when first accessed
if($name == 'form_validation')
{
if ( ! isset($this->form_validation) )
{
  isset($CI->form_validation) OR $CI->load->library('form_validation');

  $this->form_validation =& $CI->form_validation;
  $this->lang->load('form_validation');
}

return $this->form_validation;
}

This fix will be part of the next release.
