Hi everybody,
I have a line of the form:
x = hash1.reject{ |key,value| !value}.keys.join(',')
That worked fine but then I needed to do the same thing for hash2. So
I had to add another line like so:
y = hash2.reject{ |key,value| !value}.keys.join(',')
I'm trying go DRY but I can't think of an elegant way to do it -- I'm
a relative beginner in ruby. A function is an obvious candidate, but
that's probably my php thinking. Any better way to avoid the
repetition? Some fancy loop?
Thanks!
Sergei
