tests fail/ Rails site fails

[bradleyd]

I cant seem to get cache_fu going. I inherited a site that had to be moved over locally and it keeps failing with this error:

1. Error:
   test_spec {When local_cache_for_request is called} 001 [get_cache should pull from the local cache on a second hit](When local_cache_for_request is called):
   NoMethodError: undefined method []' for #<Enumerable::Enumerator:0x7f3aa057cbf0> /usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/core_ext/string/access.rb:43:infirst'

   /usr/lib/ruby/gems/1.8/gems/test-spec-0.3.0/lib/test/spec.rb:441:in `run'

I am using:

• memcache-client (1.7.5)
• rails (2.0.2)
• cache_fu verison??

Any help would be greatly appreciated.

i solved the issue. I will put this up for anyone who needs it.
Turned out that the site was written in a previous version of ruby. There is a string char method issue with rails < 2.2. So the easy fix was Copy this code to the environment.rb.

unless '1.9'.respond_to?(:force_encoding)
String.class_eval do
begin
remove_method :chars
rescue NameError
# OK
end
end
end

hope that helps.
