method
constantize
constantize(camel_cased_word)
public
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.
