Hello there all, i am writing a function that will create a list of all the
months between two given dates
def month_list ( start_y, start_m, finish_y, finish_m) # start and end month
and year
start = Time.mktime(start_y, start_m, 1)
end = Time.mktime(finish_y, finish_m)
not_finished = 1
while not_finished == 1 do
#somehow get 1 month from start
end
This is as far as i have gotten so far. What i mostly need to know is, how
do i get a datetime object
that is 1 month from start ?
<=>, >>, %w, define?, .., ... are actually nice in RUBY, although I felt they were boring when I firstly saw them.
def month_list(start_y,start_m,end_y,end_m)
st = Date.civil(start_y,start_m);
et = Date.civil(end_y,end_m);
while((st<=>et)!=1)
p st.to_s; st>>=1;
end
end

You just have to be aware that all that does is add 30 days to today's
date. This is not neccessarily the same as getting 1 month from today,
which is actually a bit more complex that one would think at first glance.

And click on ">>" or "<<" you will find Luis' suggestion totally
works. These methods step backwards or forwards by month with Date
objects. (I have to admit, I'm kind of cuious why ActionPack doesn't
just use this to get a 1.month.from_now which really is one month from
now.)

The correct way to go about with active_support/action_pack/rails it is:
require 'rubygems'
require 'active_support'
time = Time.now.months_since(1)
or
time = Time.now.months.ago(-1)
Note that active_support is the library that you're after, not
actionpack (which is the library that provides the controller/view
behaviour of rails) - it just happened to work in the previous example
because actionpack requires active_support.
require 'chronic'
puts Chronic.parse("1 month from now")
