Let’s say I have this:
@start_date = 1.month.from_now
I want to make sure that the “day” for @start_date is always 1. How can
I change the day for @start_date?

Depending on what you want:
Time.now
=> Fri Jun 01 14:47:42 -0400 2007
Time.now.next_month.beginning_of_month
=> Sun Jul 01 00:00:00 -0400 2007
1.month.from_now.beginning_of_week
=> Mon Jun 25 00:00:00 -0400 2007
Your choice.

@start_date = 1.month.from_now.beginning_of_month
Should work for ya.
Time.now.next_month.beginning_of_month
=> Sun Jul 01 00:00:00 -0400 2007
That is perfect. Thank you; is there a list of these methods somewhere?
I’ve been looking for them, but haven’t found them…

Look at the API docs for
ActiveSupport::CoreExtensions::Time::Calculations
FYI, note the difference between:
2.months.from_now
and
Time.now.months_since(2) # aka, Time.now.next_month.next_month

Posted viahttp://www.ruby-forum.com/.
The short answer (though overwhelming) is here:
The search function leads you to:
http://facets.rubyforge.org/src/doc/rdoc/more/classes/Time.html#M000174
Of course thats easy when you know the method name. If you are new to
Ruby, have patience. You will learn.
The pickaxe book is invaluable:
If you’re just looking for all the methods for the Time class
specifically, I’d suggest trying here:
http://www.ruby-doc.org/core/classes/Time.html
There’s also a list of some of the classes and methods here:
http://dev.rubycentral.com/ref/
It doesn’t look to be 100% complete, but there are a lot of methods
listed for many of the built-in classes, including Time
http://dev.rubycentral.com/ref/ref_c_time.html
The Ruby Cookbook can be helpful also, giving suggestions on different
problems and how to solve them. I need to listen to the advice given
above, since I’m also new to Ruby and need to have patience.
That is perfect. Thank you; is there a list of these methods somewhere?

Yes, good point, of course the Ruby classes wouldn’t include all the
Rails options. I just happened to have those handy because I was working
on some quick date formatting this morning. The Rails API is definitely
a more complete and appropriate choice for this list.

that they wouldn’t be helpful, you just won’t find all of “these
methods” if you limit “somewhere” to Ruby’s core docs.)-Rob
