Currently i am upgrading my application from ruby 1.8.7 to ruby 2. I got the following issue datetime.

Ruby 1.8.7 console:

u=User.find :last
 => #<User id: 1191, login: "srivaishvi@gmail.com", name: "Sri Lakshmi", email: "srivaishvi.local@gmail.com" , created_at: "2014-01-27 12:09:04", updated_at: "2014-01-28 15:57:23"> 
u.updated_at="1/13/2014"
 => "1/13/2014" 
u.save
 => true

Ruby 2 console:

u=User.find :last
 => #<User id: 1191, login: "srivaishvi@gmail.com", name: "Sri Lakshmi", email: "srivaishvi.local@gmail.com" , created_at: "2014-01-27 12:09:04", updated_at: "2014-01-28 15:57:23"> 
u.updated_at="1/13/2014"
 => "1/13/2014" 
u.save
 *****ArgumentError: argument out of range*****

I want the Ruby 1.8.7 datetime format in Ruby 2. I would like to keep using format I used in Ruby 1.8.7.

ok. Now I understand your requirement. In that case, you can change the default format through out the application. Please follow the steps mentioned in the link,

This is not the right way to update a updated_at field. Record will be updated, but it will not be the date you actually wanted.

>> u.updated_at = "1/13/2014"
=> "1/13/2014"
>> u.save
=> true
>> u.updated_at
=> Wed, 29 Jan 2014 18:12:51 UTC +00:00

  • This is juz an example how its differ from ruby 1.8.7. whereever we use date filed in in ruby 1.8.7 (1/13/2014 it will save as jan 13 but in ruby 2 its taking 13 as a month.thats why its throwing out of range.(istead of 1/13/2014 if i give 13/1/2014 it will take.)) – kannathasan Jan 29 '14 at 18:50
  • ruby 2 expecting in dd/mm/yy format.but in existing its coming as mm/dd/yy – kannathasan Jan 29 '14 at 18:56
