Hi,
I'm working on a bi-lingual (EN and FR) site and have the following:

class Tip extends DataObject{
    public static $db = array (
        "Title"=>"Varchar(255)",
        "Content"=>"HTMLText"
    );
    public static $has_one = array(
        "Image"=>"Image"
    );
    static $many_many = array(
        'RelatedProducts'=>'Product',
    );
    private static $translatable_fields = array(
        'Title',
        'Content',
        'RelatedProducts'

    );

For products:

Product is already translated by using translatable, so I have 2 pages for the same product, one for EN and one for FR
class Product extends Page {

	private static $description = 'Use this PageType to create Products in the site.';
	// private static $icon = 'mysite/images/product';
	
	private static $db = array(
		'Headline' => 'HTMLText',

	);


	public static $has_one = array(
		'PrimaryImage' => 'Image',
       
	);
	
	static $has_many = array(
        'ProductImages' => 'ProductImage',
        'ProductDirections' => 'ProductDirection',
        'AvailableSizes' => 'AvailableSize'
        
    );
    public static $belongs_many_many = array (
      'ProductFeatures' => 'ProductFeature',
      'Recipes'=>'Recipe',
      'Tips'=>'Tip',
		  'CollectionProgramOptions' => 'CollectionProgramOption',
    );

Is there a way to create an additional column in the TIp-Product table to have Product_id_fr?

And I will also appreciate help on how to add these fields to the my form. (Content and Title are working fine).

Thanks!
