Hi @cguess, thanks for opening this issue, I'll try to help.
Mechanize does not override the File
base class. The behavior you're seeing just how constant resolution works in Ruby.
#!/usr/bin/env ruby
class Base
class File
end
end
class Subclass < Base
def foo
File
end
end
Subclass.new.foo # => Base::File
File # => File
When referencing a constant within a "namespace" (that is, a module or class that nests another module or class), the constant name is looked for in the local module (Module.nesting
), then the ancestors, and only if something isn't found does it proceed to the top-level (global) classes. So in the above case it finds Base::File
when it proceeds through the class's ancestors.
You can work around this by being explicit that you want the global File
class. To do this, use ::File
:
#!/usr/bin/env ruby
class Base
class File
end
end
class Subclass < Base
def foo
::File
end
end
Subclass.new.foo # => File
File # => File
Hope this helps!
