Date field not stored any more
Reported by Markus Liebelt | August 9th, 2008 @ 12:52 PM | in 2.x
I have a simple application that stores tasks. A task has a due_date which is mapped on the DB as a date. === schema.rb === create_table "tasks", :force => true do |t|
t.date "due_date"
...
Then loading a task from the db, changing the date, and storing it again, noting is changed:
D:\ruby\rails\app>ruby script\console Loading development environment (Rails 2.1.0)
t= Task.find(193) => # t.due_date= t.due_date + 1 => Tue, 12 Aug 2008 t.save => true t= Task.find(193)
=> #
The same code has worked in Rails 2.0.2, so I downgraded afterwards to 2.0.2 again.
Does any one knows the reason for that?

Sorry for the formatting of the source. Here it is again:
D:\ruby\rails\app>ruby script\console Loading development environment (Rails 2.1.0) >> t= Task.find(193) => #<Task id: 193, due_date: "2008-08-11"> >> t.due_date= t.due_date + 1 => Tue, 12 Aug 2008 >> t => #<Task id: 193, due_date: "2008-08-12"> >> t.save => true >> t= Task.find(193) => #<Task id: 193, due_date: "2008-08-11"> -

After replacing the old code:
@attributes["due_date"]= new_date
Through:
self[:due_date]= new_date
everything was fine. So my old code had to change so that the change from Release 2.0 to 2.1 (don't use @attributes in your code) could work. I found the pattern self[:<att_name>] in the book "The Rails Way" by Obie Fernandez by accident (a lucky one).
So the ticket should now be fixed
