Handling nested Grape mounts?

[fatmcgav]

I'm trying to use Grape for providing 'versioned' APIs with Padrino.

I'd like to just mount a single API class in Padrino, e.g.:
Padrino.mount('API', :app_file => Padrino.root('api/base.rb'), :app_class => 'API::Base').to('/api')
Which then mounts the version APIs.

However whenever I try this I get an 'Unitialized Constant' error.
Further details can be found here: https://groups.google.com/forum/?nomobile=true#!topic/padrino/9aA5wFpWp4k and here: fatmcgav/padrino-grape-example@0e3a6c6

The Unitialized Constant error comes from the v1.rb file not being required.

So the easy fix for that is obviously:

diff --git a/api/base.rb b/api/base.rb
index dd5fd3a..9519b43 100644
--- a/api/base.rb
+++ b/api/base.rb
@@ -1,3 +1,5 @@
+require_relative "v1"
+
 module Aurora
   module API
     class Base < Grape::API

It might break the reloader, but I am not sure if the reloader will even work for Grape applications.

@adam12 Ah, that was a relatively easy fix...

Though I'm now seeing routes listed twice...

I'm not sure how much help I'll be there sadly.

Hi @farcaller, I've setup an example app under https://github.com/wikimatze/padrino-nested-grape-mounts which do the nesting in a way I understand modules in grape as explained under https://github.com/ruby-grape/grape#modules - just follow the README in https://github.com/wikimatze/padrino-nested-grape-mounts/blob/master/README.md to see what I did.
