method
define_attr_method
define_attr_method(name, value=nil, &block)
private
Defines an "attribute" method (like inheritance_column or table_name). A new (class) method will be created with the given name. If a value is specified, the new method will return that value (as a string). Otherwise, the given block will be used to compute the value of the method.
The original method will be aliased, with the new name being prefixed with "original_". This allows the new method to access the original value.
Example:
class A < ActiveRecord::Base define_attr_method :primary_key, "sysid" define_attr_method( :inheritance_column ) do original_inheritance_column + "_id" end end
