#property(name, type, options = {}) ⇒ Object

Override DataMapper’s property class method to accept as an option filter. filter Hash with the following pairs:

  • :to - Name of property to filter to; this should not be explicitly declared as a property.

  • :with - Either 1) Name of the property (as a symbol) that designates filter (does not need to be explicitly declared as a property) or 2) A semi-colon delimited String represented filters to use (or an Array of strings).

  • :default - A semi-colon delimited String represented filters to use (or an Array of strings) if the filter column is blank.
