[MacRuby-devel] Using Virtus or SmartProperty as outlets?
I've done a bit of Googling, but couldn't find anything on this. I'd like to use something like SmartProperties (for lightweight situations) or Virtus (when I absolutely must have industrial-strength validations, etc) as outlets. My experiments, such as they are, aren't helping me any! What, if anything, am I doing wrong? My experiments are basically: require 'virtue' class TestClass attribute :test_attr, String end And then I try to "wire" up a text field from IB to the attribute; the result? Nothing happens. Basically, I need to make sure that when I ask for an integer, I get an integer. And when I want a string - I can reject anything but strings. But sometimes I'd like the "defaults" capability of Virtus & SmartProperty, and I'd definitely like the industrial-strength validations of Virtus when I'm working against the database. In MacRuby terms, am I addressing the right problem!? Did I miss something in my Googling? Thanks in advance!

Hi Carolyn, I can't help with Virtus or SmartProperty, but I think for MacRuby to recognise an outlet in your code you need to use 'attr_accessor', not 'attribute'. Maybe you could use the various types of input fields to ensure the values are numbers or strings, and then query their stringValue or integerValue. Hope that helps. -- Stephen Horne On 21/11/2012, at 20:04, Carolyn Ann Grant wrote: > I've done a bit of Googling, but couldn't find anything on this.

Re: [MacRuby-devel] Using Virtus or SmartProperty as outlets?
Sorry - I didn't make that clear! You're right, Stephen: I'd like to Virtus' "attribute" or SmartProperty's "property" *instead* of attr_accessor. I can roll my own solution, but I'd like to not have to! (Besides laziness, and the strong possibility of introducing bugs into any solution I come up with, I really like the strong validations and coercions of Virtus - and it's useful for database entries. And it's already written and mostly debugged.)

"Basically, I need to make sure that when I ask for an integer, I get an integer. And when I want a string - I can reject anything but strings." Can't you use Ruby services like is_a? to force it ?

Re: [MacRuby-devel] Using Virtus or SmartProperty as outlets?
What happens if you use BOTH attr_accessor and attribute - the first for the IB outlet, and the other for validation. Just a thought.
