.find not accepting string containing UUID

[caldwecr]

@pyromaniac - trying to following the example in the documentation that indicates

let(:guid) { "1dd74dd0-d116-11e0-99c7-5ac5d975667e" }
it "should be able to find an email by the uuid" do
  Email.find(guid).id.to_s.should == guid
end

This doesn't appear to work. When I try this myself I get ...

Advice?

[vigneshprakasam33]

I encountered the find bug in my application as well. For development log, the SQL statement for
Ivr.find_by_uuid("d9d98467-26e6-4437-87f7-61e6605bb6f5") is,

SELECT ivrs.* FROM ivrs WHERE ivrs.uuid = 'd9d98467-26e6-4437-87f7-61e6605bb6f5'

The where clause is not comparing in binary.
