I'm getting a weird failure when trying to compare two datetimes. The
failure message is:
'Prompt as a featured prompt should set featured_on for public prompts'
FAILED
expected: Thu May 22 16:31:38 -0400 2008,
got: Thu May 22 16:31:38 -0400 2008 (using ==)
My test:
it "should set featured_on for public prompts" do
date = 2.days.ago #cache timestamp
@prompt = create_prompt(:scope => "public", :featured_on => nil)
@prompt.make_featured :date => date
@prompt.featured_on.should == (date)
end
My model method:
def make_featured(options = {})
unless scope == "private"
options = {:date => Time.now}.merge(options)
date = options[:date].to_s(:db)
self.featured_on = date
self.save
else
false
end
end
I recently upgraded to Rails 2.1_RC1, so I'm hoping that didn't foul
anything up. Also, what's weird is that in my method I'm setting
:featured_on to date.to_s(:db). So if I run a prompt.inspect in the
console, it returns "featured_on: '2008-05-24 16:20:45'", but if I just
type "prompt.featured_on" in the console, it returns Sat May 24 16:20:45
-0400 2008, so I don't know if rails is doing any auto-conversion there.
But that seems almost totally unrelated to my test failing when
comparing two identical date values.
Could it be you're comparing date in your spec, which is of class
Time, to a string (the value of featured_on)?
That doesn't seem to be the problem. If I convert both values in the
comparison to String, it will pass the test, but not if I just convert
the value I'm comparing against.
It also seems that regardless of whether I pass in a Time object or a
String to the record, Rails returns a Time object (which I assume is
because the column is set as datetime). Both of the objects I'm
comparing in my test belong to the Time class.
