using a local variable for method calls

[Reid Oda]

hello all,

first off, thanks for all the help this board/list has offered. it has
been fantastic.

a workmate of mine and i are puzzling over this problem. here is a bit
of pseudo code that represents it:

somehash.each_key do |key|
update.key "something"
end

obviously there is a problem with using the "key" variable to make the
method call. how can we accomplish this elegantly? we've considered
this:

somehash.each_key do |key|
eval("update.#{key}(\"something\")")
end

but that seems a bit cludgey. does anyone have some advice?

Check out the _send_ method.

update._send_(key, *args)

 

[Reid Oda]

awesome!

Check out the _send_ method.

update._send_(key, *args)

Check out the _send_ method.

update._send_(key, *args)

you surely mean
update.send(...) or
update.__send__(...)
right?

Cheers

Maybe he tried to introduce a new way ... ;-)
