At present, there isn't any effort going on in this area. If you want to contribute, this would be a very big contribution. However, be warned - there is a reason we haven't addressed this issue. On a model level, it shouldn't be too difficult to implement - allow primary_key=True to be defined on multiple fields, and interpret those fields appropriately when the table is created. You would also need to modify the query syntax to ensure that queries over pk accept tuples rather than just being a simple alias for the primary key field. You will have more difficulty with the Admin application and generic views. Both of these features rely upon the ability to install URLs like: /path/to/object/42/ -> edit object 42 This works fine if you have a single column primary key; however, if you have multiple column primary keys, this isn't so easy to do. To date, every proposed syntax for URL spaces supporting multiple primary keys has either been syntactically ambiguous (e.g., /path/to/object/42,37 - which works unless the primary key has a comma in it), or very inelegant (/path/to/object/42/37/ - which implies a heirarchy where there isn't one). Any proposal for adding multiple primary keys would need to address this very large issue.
