safe_constantize(camel_cased_word) public Tries to find a constant with the name specified in the argument string.
'Module'.safe_constantize # => Module 'Test::Unit'.safe_constantize # => Test::Unit
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' 'C'.safe_constantize # => 'outside', same as ::C end
nil is returned when the name is not in CamelCase or the constant (or part of it) is unknown.
'blargle'.safe_constantize # => nil 'UnknownModule'.safe_constantize # => nil 'UnknownModule::Foo::Bar'.safe_constantize # => nil
