#form_property(property, row_type, options = {}) ⇒ Object

Relates a property to a RowType. EX form_property :my_title => :string form_property :my_date => :date, :transform => lambda { |value| some_function(date) }

Parameters:

  • property —

    is the name of the attribute to KVO

  • row_type —

    is the Formotion::RowType to use for that attribute

  • options (defaults to: {}) —

    are the extra options for this model. Keys can include any usual Formotion::Row keys to override, plus :transform, which is a single-argument lambda for transforming the row’s string value before it’s synced to your model.
