Rails - Aug 2011 - Accessing datetime elements from hash passed to method

I''m passing hash (called ''params'') to a method. Some
keys (one of them
is called ''starts_at'') in that hash have date as a value
(taken from
datetime_select helper). I want to access the date elements like date
only or time only but I''m just out of ideas.


 def self.new_meeting(params)
    str = params[''starts_at(1i)'']
    puts  str
 end

This returns nothing.

 def self.new_meeting(params)
    str = params[:starts_at]
    puts  str
 end

This returns whole date with time.

Ruby 1.9.2
Rails 3.0.7

Can you help a newbie??

Time/date objects have methods like year, month, day etc. which return
the individual components

I don''t know the format of you params string but you can probably use
something like
starts_at = Time.parse( params[:starts_at] )
puts starts_at.year

Well, you lied.  You didn''t have a Date, you had a String.

I''m not saying that I know what I''m talking about :)

 I''m newbie but I didn''t lie.

What I said was:
"...date as a value (taken from
datetime_select helper)"

if it was a String then datetime_select returns a string, or Dates are 
Strings but with some order.

I''m getting confused now.

I think values in params hash are always strings as they are just the
strings taken from the http request.  As you said, you never said that
you had a Date object.
