Hey all,
If I’m instantiating a instance of a class at using Object.const_get.
How can I destroy it so that next time it reloads and code changes will
take effect?
Thanks.

I am not sure what you mean here. You don’t instantiate anything
using const_get. You just get the reference to the existing object.
If you want to redefine class objects (without warning), you remove
the constant using remove_const(), and reload the program using
load(). But I’d recommend restarting the program, unless reloading is
absolutely necessary.

That’s pretty much what I was looking for. The problem I’m having is
with a plugin in Rails. Once it runs, if code is executed, then changed
at all, I have to restart Rails. Default rails controllers update just
fine. They’re probably using the remove_const(). But with my plugin I
want to have the same functionality…
Are there any major risks doing this? Wouldn’t seem like it.
Thanks

Are you talking about the way Rails reloads classes in development
mode? You can enable this in your own classes using:
class MyClass
include Reloadable
end

That’s another good solution. Thanks.
