The application that the work team is working on started throwing errors when I updated datamapper (and the dependent gems) from 1.0.2 to 1.1.0
I wrote this simple code to isolate the problem. It works fine with 1.0.2 but throws an error with 1.1.0

require 'rubygems'
require 'datamapper'

puts "hello 1"
DataMapper::Logger.new("test.log", :debug)
DataMapper.setup(:default, 'oracle://user:password@webtest1')

class TestTab

include DataMapper::Resource

property :tab_id, Integer, :key => true property :name, String, :length => 20 property :desc, String, :length => 20 end

DataMapper.finalize
TestTab.auto_migrate!

@testTab = TestTab.new(:tab_id => 1, :name => 'One', :desc => 'One Again') @testTab.save @testTab = TestTab.new(:tab_id => 2, :name => 'Two', :desc => 'Two Again') @testTab.save

t = TestTab.first
puts ":#{t.desc}:"

With 1.0.2 the output is:

:!ruby test2.rb hello 1
DataObjects::URI.new with arguments is deprecated, use a Hash of URI components

(/usr/local/lib/ruby/gems/1.9.1/gems/dm-do-adapter-1.0.2/lib/dm-do-adapter/adapter.rb:215:in `new') :One Again:

With 1.1.0 the output is:

/home/afernandes/test_gems/test_dm-->ruby test2.rb hello 1
DataObjects::URI.new with arguments is deprecated, use a Hash of URI components (/usr/local/lib/ruby/gems/1.9.1/gems/dm-do-adapter-1.1.0/lib/dm-do-adapter/adapter.rb:231:in new') /usr/local/lib/ruby/gems/1.9.1/gems/dm-oracle-adapter-1.1.0/lib/dm-oracle-adapter/adapter.rb:105:inselect_statement': undefined method `blank?' for nil:NilClass (NoMethodError)

    from test2.rb:26:in `<main>'

/home/afernandes/test_gems/test_dm-->

I do understand that the warning about the Hash has been fixed in 1.1.1, but I could not find any information as to why the error "undefined method `blank?' for nil:NilClass (NoMethodError)" was showing up.

Any help would be appreciated. I am not a seasoned ruby developer and could have missed something.

Thank you :-)
