Rails: How I can get yesterday's date?

Question

How can I get yesterday's date?

maybe:

@get_time_now    = Time.now.strftime('%m/%d/%Y') / 86400  

or

@get_time_now    = Time.now.strftime('%m/%d/%Y') - 1.day 

or

@get_time_now    = Time.now. / 86400  

86400 = 1 day, right? (60 * 60 * 24)

Answer 1

Rails

For a date object you could use:

Date.yesterday 

Or a time object:

1.day.ago 

Ruby

Or outside of rails:

require 'date'  Date.today.prev_day
