Date#wday gives the "weekday" number: 0=Sunday, 6=Saturday 1..5 is an inclusive Range (1..5).include?(x) is a predicate that is true if x falls in the Range, it's like (1 <= x && 5 <= x) I see that you put the code into your view. You probably want to keep this kind of logic in your controller (or possibly a helper). In any case, in a view you could put: <%= (1..5).include?(Date.today.wday) ? "weekday" : "weekend" %> <% %> bracket Ruby code <%= %> do too, but the value of the contained expression as a string is output to the page. -Rob > On Jun 17, 7:33 pm, Rob Biedenharn <[email protected]> > wrote: >> On Jun 17, 2009, at 8:08 PM, E.
