Hooks which *can* fail a response? #527

Open alechenninger opened 8 years ago

I kind of like hooks as an extension mechanism. What if you could use a hook for additional validation? If a hook could fail a request, you could use it for this kind of thing. So maybe it would be cool allow hooks to deliberately fail a request, or even modify it.

Hooks as extensions is really only a powerful construct if hooks could be loaded at runtime (which there is another issue for somewhere).

All hooks are processed after the CRUD operation. In the case of all but read, this means data changes are made. We don't have transactions with mongo backend.

I think to fail a request or modify the request we need a pre-CRUD capability (similar to pre insert, update, delete trigger in RDBMS). It would make sense for these hooks to cause failure.
