Coverage remained the same at 92.74% when pulling 3c3c5c6 on ericschultz:loosen_activesupport_to_3 into 064ecfb on ruby-grape:master.

I tested it with 'activesupport', '~>3.0' → uses 3.2.22.5, there one error occurs …

 1) Grape::Entity except option for nested entity
     Failure/Error: Address.represent c[:address], Grape::Entity::Options.new(o.opts_hash.except(:full))
     
     NoMethodError:
       undefined method `except' for {:attr_path=>[:address]}:Hash
     # ./spec/grape_entity/hash_spec.rb:19:in `block in <class:Company>'
     ...
     # ./lib/grape_entity/entity.rb:490:in `serializable_hash'
     # ./spec/grape_entity/hash_spec.rb:36:in `block (2 levels) in <top (required)>'

it seems, that if the people will really use version 3.x of it, then it didn't work correct

… so I'll close it

Sorry about that.

Just looking into this, the problem seems to be that activesupport's extensions for the hash class aren't being included in the spec suite. When I add require 'active_support/core_ext/hash' to the top of spec_helper.rb, the specs pass on 'activesupport', '~>3.0' I'm not sure on the best way to address this (I'm still a bit of a beginner to Ruby).

I'm happy to correct the problem if you have any suggestions.

ok, then it is so, I'll re-open the issue
