Be careful here, depending on your user base of course.
What will you do if {params[:id]} (I know, incorrect syntax), evaluates to
"delete!" or something else.
If you have a completely trustworthy user base (such as only you, or only
your colleagues, whom you should trust implicitly, otherwise, why would you
want to work with them), then once you figure out the right syntax (which
probably involves the use of #send, or something like that), you should be
fine.
If you are exposing this to the wild world wide web (WWWW), then I would
recommend against this.
You would probably be better off writing a helper function that mapped
params[:id] into one of the acceptable values. Perhaps something like:
def better_form_of_low(user, id)
case id
when :low
user.low
when :high
user.high
end
and call that with better_form_of_low(@user, params[:id])
just my $.02 from my paranoid mind :-)
