Hi *, I have a model like this: class Trait include DataMapper::Resource
property :id, Serial property :name, Slug, :required => true property :data, Decimal, :required => true has n, :items, :through => :assignments has n, :assignments end and if I do: irb(main):029:0> t = Trait.new => #<Trait @id=nil @name=nil @data=nil> irb(main):030:0> t.data = 1.0 => 1.0 irb(main):031:0> t => #<Trait @id=nil @name=nil @data=nil> irb(main):032:0> t.name = "FOO" => "FOO" irb(main):033:0> t => #<Trait @id=nil @name="foo" @data=nil> irb(main):034:0> t.save => false irb(main):035:0> t.errors.inspect => "#<DataMapper::Validations::ValidationErrors:0x00000005bb5e40 @resource=#<Trait @id=nil @name=\"foo\" @data=nil>, @errors={:data=>[\"Data must not be blank\"]}>" can someone explain me why I'm not able to set the data attribute?
