Notes & Questions

[wadetandy]

Wanted a place to capture random thoughts while looking over the code and also a place to address questions you ask in your comments.

Do we actually want to log?

This probably should depend on the specific error type? If the response is >=500, I'd think logging is appropriate. If it's something like a 400 bad request that we have gotten from our request validator, then logging is probably not necessary.

Any downside to including this in all Rails controllers?

Would follow the lead of some other projects and have this as a configurable option:

Graphiti::Rails.configure do |c|
  c.base_controller = 'ApplicationController'
end

The list of errors you pulled from graphiti to merge into action_dispatch.rescue_reponses doesn't include the new InvalidRequest error, which will be one of the critical ones we need to handle.

That has a custom error handler subclass in graphti_errors: https://github.com/graphiti-api/graphiti_errors/blob/master/lib/graphiti_errors.rb#L23-L26

I wrote my own notes here: https://gist.github.com/richmolj/ded6c99353ead759785caaeeb68a7e60

To touch on a few things Wade mentioned:

If the response is >=500, I'd think logging is appropriate. If it's something like a 400 bad request that we have gotten from our request validator, then logging is probably not necessary.

I think these are good defaults, we just need the ability to override with register_graphiti_exception FooError, log: false. One example is avoiding logging on 404 - maybe, maybe not. I think we have a few internal BGov errors as well were we just want to eliminate legacy noise.

Would follow the lead of some other projects and have this as a configurable option:

I'd prefer including a mixin as a little more explicit. The downside to applying to all controllers is running AMS/whatever and graphiti side-by-side.

@wadetandy for now, I think we'll only log fatal exceptions. See eeb6b6d.

For easier discussion, I've split these up into multiple issues. If I missed anything, please open a new issue.
