How to make ActiveRecord return timestamp as TimeWithZone in a minimal test case?

Question

I'm trying to come up with a minimal test case for ActiveRecord 4.0. What I have is this gist which fails with this message:

  1) Failure:
BugTest#test_association_stuff [millisecond_resolution.rb:28]:
Expected: "ActiveSupport::TimeWithZone"
  Actual: "Time"

In a full Rails app, this does return ActiveSupport::TimeWithZone. What I'm missing is the link between AS and AR so that the latter returns timestamps as TimeWithZone. I've already added

ActiveRecord::Base.default_timezone = :local
ActiveRecord::Base.time_zone_aware_attributes = true

to no avail. I'm also aware of the lazy_load_hooks in AS but am note sure if they are applicable.

What am I missing here? Am I on the wrong track?

Answer 1

No time zone is set in your test. You have to set the time zone.

Time.zone = 'Berlin'

See http://api.rubyonrails.org/classes/ActiveSupport/TimeWithZone.html for more details.

Answer 2

Alright mate,

I've only got rails 4.0.0 on my computer, but a quick acking brought me to this:

# activesupport-4.0.0/lib/active_support/time_with_zone.rb:39

# Report class name as 'Time' to thwart type checking.
def self.name
  'Time'
end

Hope that gets your nearer to a solution.
