Starting with UUID - question

Hi!

I am trying to implement this in my Yii2 project but I do not succeed ^^, do I realy need to extend from included Model and Controller + add the behavior to all + set the formatter in config? Or is it okay to just extend from Model and Controller?

After I extended my base Model and Controller and added the behavior I got an error from the API end-point 'Unsupported format'. Should I set the id field in the SQL database to some other data type, like binary or something?

Thanks in advance!
