Signature
constantize(camel_cased_word)Tries to find a constant with the name specified in the argument string.
constantize('Module') # => Module
constantize('Foo::Bar') # => Foo::Bar
The name is assumed to be the one of a top-level constant, no matter whether it starts with “::” or not. No lexical context is taken into account:
C = 'outside'
module M
C = 'inside'
C # => 'inside'
constantize('C') # => 'outside', same as ::C
end
NameError is raised when the name is not in CamelCase or the constant is unknown.
