hi, I am having some problem here with field Decimal My Class:
require 'dm-core' class Registry include DataMapper::Resource property :num, Decimal, :key => true, :precision => 20, :scale => 0 end require 'dm-migrations' DataMapper.finalize DataMapper.setup(:default, 'sqlite::memory:') DataMapper.auto_migrate! My Test: // I start irb $ irb -r ./dm /home/arthur/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>': It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. // and create a new registry ruby-1.9.3-p0 :001 > r = Registry.new(:num => 321512420108210029) => #<Registry @num=#<BigDecimal:9771c54,'0.3215124201 08210029E18', 18(27)>> // bigdecimal is showing correct num ruby-1.9.3-p0 :002 > r.save => true ruby-1.9.3-p0 :003 > Registry.all => [#<Registry @num=#<BigDecimal:98358e8,'0.3215124201 08210048E18', 18(27)>>] // num is wrong ruby-1.9.3-p0 :004 > Registry.all.first.num.to_i // trying to convert to int => 321512420108210048 // wrong value ruby-1.9.3-p0 :005 > BigDecimal.new(321512420108210029).to_i // here, aparently bigdecimal is working correct => 321512420108210029 Anyone can help me ?
