|
*
|
|
* For example: the list of Animal Groups in Farm Livestock, or the list of

*
|
|
* The reason we override is so that we can add a little extra logic to the
|
|
* join so that only non-archived assets are included. This is provided as an
|
|
* option in the relationship handler, so it can be added only when necessary.
