I am trying to create a taxonomy term reference field or the equivalent in a View that uses the uuid of a field in a custom table. This field can contain multiple uuids.
My first approach after having issues with the views_handler_field_taxonomy ( because the table does not contain the vid and tid fields ) was using joins and another table that contained all the necessary taxonomy fields. Although I got it to work the multiple joins caused the results to become pretty ugly ( lots of duplicates ). I may have to use this approach and clean up the results with custom code but I would definitely prefer not to.
So the question. Is there any straightforward way I'm missing to get my custom database field of comma separated uuids treated like a taxonomy term reference field by Views? I have tried a variety of different relationship handlers as well as field handlers in my hook_views_data but no luck. I have found very limited documentation and only the simplest tutorials for custom views field and relationship handlers. Any links to good ones and/or good sample code would be greatly appreciated.
I would also be completely fine with a way to treat a custom entity property as a taxonomy term reference field.
