I've tried the following:
def next_seven_days
today = Date.today
(today .. today + 7).each { |date| puts date }
end
But this just gives me the first and last date. I can't figure out how to get all the ones in between.
I was trying to follow the example here: http://www.whynotwiki.com/Ruby_/_Dates_and_times
Your function RETURNS an enumeration designated by 2011-07-07..2011-07-14 which is displayed in your view, but your puts prints to STDOUT which is not going to be your view, but the console screen your server is running in =)
If you want your view to show a list of the seven days, you need to actually create the string that does that and RETURN that :)
def next_seven_days
outputstr = ""
today = Date.today
(today..(today+7.days)).each { |date| outputstr += date.to_s }
return outputstr
end
