If I give you:

module Something module SomethingElse class Foo end end end

How do you get the class name of "Foo"? In the console, I have something similar to the example, but when I do .name on it it doesn't print out what I expect.

This is whats in my console:

pry(main)> AisisWriter::Controllers::CommentsManagement::CommentsHandler.name => "AisisWriter::Controllers::CommentsManagement::CommentsHandler"

What I expect is just "CommentsHandler"

You can do:

AisisWriter::Controllers::CommentsManagement::CommentsHandler.name.split('::').last || ''

If you have ActiveSupport included, try demodulize method

Note that you must call :demodulize on the string, not the class. For instance: A::B::C.name.demodulize (return string via :name, then call :demodulize)

It's quite simple.

AisisWriter::Controllers::CommentsManagement::CommentsHandler.name.split(':').last

It's better to split on "::". End result is the same, but reveals intention better.
why, if the single colon doesn't appear anywhere else in the name?
Result of splitting on "::" can be used for a couple of other tasks. Result of splitting on ":" is useless (except for this case) because of the empty strings in it.
yes, but I'm not initializing this array or using it for anything else.
Anyhow, the separator here is "::", not ":". Benefit of not using full separator is unclear to me.
