Helper functions not available in rescue_from

[skwp]

Hi, we are trapping errors in rescue_from but unable to log them because the logger variable appears out of scope. Any ideas on how to access it? Thanks.

I was able to get around this by defining a constant. It's a bit ugly but it works...something like this:

module API
   LOGGER = Logger.new(...)
   logger LOGGER

   rescue_from :all do |e|
     LOGGER.error e
   end
end

I think you should leave it open. I think logger should be available there without hacks

none of the helpers are available in rescue_from either, no?

correct, no helpers are available there. I think it's a bit strange.

+1 Fixing this would be GREAT.

+1, the error! is not available, so I can't pass error code

+1 I just ran into this issue as well, trying to access error! and a helper wrapping error! from a rescue_from block.

Also ran into this error today.

You can access helpers, etc from a rescue_from like this:

rescue_from StandardError do |e|
  env['api.endpoint'].helper_method
end

@cmaitchison that tip was super helpful thanks!

Thanks for the workaround. This is a huge pain. Please fix!

Would be great to fix this, also the workaround does not work for me:

class App < Grape::API
  rescue_from ActiveRecord::RecordNotFound do |e|
      env['api.endpoint'].error!( e.message, 404 )
  end
end

Gives:

ArgumentError: uncaught throw :error

any ideas?

thanks!
