I''m sorry if this is really dumb, but I can''t find the answer.
How do I clear (or unset) a session variable? Not the whole session,
just one item.
I tried treating the session as a hash, but
session.delete(:mykey)
does not work.

session[:key] = nil seems to be the accepted way of doing this. session is not just a hash, and if you look at the source, #delete takes no parameters and actually clears the entire session. A lot of people (including me) run into this, and I''m still not sure why it was done this way. What''s wrong with making session.clear (or session.empty) empty it out and keeping session.delete(:key) to work like a hash? The current implementation definitely violates the Principle of Least Surprise.
