Re: [DataMapper] Decimal datatype

[Antonio Antillon]

You are asigning foo to the name field... and nothing to the data field... in your model, you declared data as a requires field... if you don't assign anything to it, it's nil... and data must have a value... that's why.

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,

I see him setting data to 10 - did you miss that? I'm not where I can try this, but I'd rename data and see if that helps. DM has internal methods, perhaps you have a a collision?
