Time not updating in heroku

Question

I'm seriously confused what could be going wrong.

I'm logged into heroku run console and trying to update a timestamp on my database.

I've run User.find(6) to see that the user has a :next_click = 2000-01-01... i don't know why it's that value, but anyway, I do User.update 6, {:next_click => Time.utc(2015)} and it seems to update properly saying 2015-01-01 00:00:00, however when I do another User.find(6) it seems the time has switched back because it's not 2015-01-01 00:00:00.

I'm really confused why it's not. Any insight?

irb(main):033:0> User.update 6, {:next_click => Time.utc(2015) }
  User Load (34.0ms)  SELECT "users".* FROM "users" WHERE "users"."id" = $1 LIMIT 1  [["id", 6]]
   (1.8ms)  BEGIN
   (2.2ms)  UPDATE "users" SET "next_click" = '2015-01-01 00:00:00.000000', "updated_at" = '2012-05-24 00:13:26.197358' WHERE "users"."id" = 6
   (2.2ms)  COMMIT
=> #<User id: 6, name: "mazlix", gold: 10, points: 10, next_click: "2015-01-01 00:00:00", created_at: "2012-05-23 23:40:39", updated_at: "2012-05-24 00:13:26">
irb(main):034:0> User.find(6)
  User Load (2.4ms)  SELECT "users".* FROM "users" WHERE "users"."id" = $1 LIMIT 1  [["id", 6]]
=> #<User id: 6, name: "mazlix", gold: 10, points: 10, next_click: "2000-01-01 00:00:00", created_at: "2012-05-23 23:40:39", updated_at: "2012-05-24 00:13:26">

The same thing happens with u = User.find(6) u.next_click = Time.utc(2013) then u.save

irb(main):001:0> u = User.find(6)
  User Load (38.8ms)  SELECT "users".* FROM "users" WHERE "users"."id" = $1 LIMIT 1  [["id", 6]]
=> #<User id: 6, name: "mazlix", gold: 10, points: 10, next_click: "2000-01-01 00:00:00", created_at: "2012-05-23 23:40:39", updated_at: "2012-05-24 00:57:28">
irb(main):002:0> u.next_click = Time.utc(2013)
=> 2013-01-01 00:00:00 UTC
irb(main):003:0> u
=> #<User id: 6, name: "mazlix", gold: 10, points: 10, next_click: "2013-01-01 00:00:00", created_at: "2012-05-23 23:40:39", updated_at: "2012-05-24 00:57:28">

   (2.2ms)  COMMIT

irb(main):006:0> User.find(6)

app/models/user.rb:

class User < ActiveRecord::Base
  attr_accessible :gold, :name, :next_click, :points
end

Answer 1

You've created a time column. Slightly confusingly, even though in ruby Time stores time + date, in the database world the concept of a pure time of day (ie just hours/minutes/seconds) exists and that's what you get when you add a column of type :time to your migration.

Ruby itself doesn't have a class that represents a time without a date so rails uses an instance of Time but ignores the date bit.

If you want a column that stores both time and date, change the column to a :datetime one (you'll still get a Time instance back in most cases.

Answer 2

In your ActiveRecord can use the data type :timestamp or :datetime to store the correct date format.
