The sql_expr extension adds the sql_expr method to every object, which returns an wrapped object that works nicely with Sequel’s DSL by calling Sequel.expr:
1.sql_expr < :a # 1 < a false.sql_expr & :a # FALSE AND a true.sql_expr | :a # TRUE OR a ~nil.sql_expr # NOT NULL "a".sql_expr + "b" # 'a' || 'b'
Objects are blank if they respond true to empty?
# File lib/sequel/extensions/blank.rb, line 12 12: def blank? 13: respond_to?(:empty?) && empty? 14: end
Return the object wrapper in an appropriate Sequel expression object.
# File lib/sequel/extensions/sql_expr.rb, line 13 13: def sql_expr 14: Sequel.expr(self) 15: end
Disabled; run with --debug to generate this.
