Class: Sequel::BasicObject

Inherits:
BasicObject
Defined in:
lib/sequel/sql.rb,
lib/sequel/sql.rb

Overview

If on 1.9, create a Sequel::BasicObject class that is just like the default BasicObject class, except that missing constants are resolved in Object. This allows the virtual row support to work with classes without prefixing them with ::, such as:

DB[:bonds].filter{maturity_date > Time.now}

Constant Summary collapse

KEEP_METHODS =

The instance methods to not remove from the class when removing other methods.

%w"__id__ __send__ __metaclass__ instance_eval instance_exec == equal? initialize method_missing"
