A Trash is a ‘translated’ Dash where the keys can be remapped from a source hash.
Trashes are useful when you need to read data from another application, such as a Java api, where the keys are named differently from how we would in Ruby.
Defines a property on the Trash. Options are as follows:
:default
- Specify a default value for this property, to be
returned before a value is set on the property in a new Dash.
:from
- Specify the original key name that will be write only.
# File lib/hashie/trash.rb, line 17 def self.property(property_name, options = {}) super if options[:from] translations << options[:from].to_sym class_eval " def #{options[:from]}=(val) self[:#{property_name}] = val end " end end
Set a value on the Dash in a Hash-like way. Only works on pre-existing properties.
# File lib/hashie/trash.rb, line 32 def []=(property, value) if self.class.translations.include? property.to_sym send("#{property}=", value) elsif property_exists? property super end end
