Instance Method Details

#delegate(field, args = {}) ⇒ Object

Provides a delegate class method to expose methods in metadata streams as member of the base object. Pass the target datastream via the :to argument. If you want to return a unique result, (e.g. string instead of an array) set the :unique argument to true.

class Foo < ActiveFedora::Base
  has_metadata :name => "descMetadata", :type => MyDatastream 

  delegate :field1, :to=>"descMetadata", :unique=>true
end

foo = Foo.new
foo.field1 = "My Value"
foo.field1                 # => "My Value"
foo.field2                 # => NoMethodError: undefined method `field2' for #<Foo:0x1af30c>
