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?
TIA,
ngw
