Time.now-incidents.first.created_on will return you the number of
seconds in Numeric, that’s why you can’t call the method ‘hours’ on it.
I haven’t seen a method which would convert seconds in hours for you, if
there really isn’t one, you’ll have to make the convertion to hours
yourself…

Cheers.

(Time.now - incidents.first.created_on) / 1.hour

I do not think that 1 responds to that message.
but using 3600 instead should do the trick.

Neither do I…
However, if you are using Rails and ok with requiring active_support,
that enables 1.hour for you.

but using 3600 instead should do the trick.

In this case I’d vote for this option.

Hi Robert,

the original code:

(Time.now-incidents.first.created_on).hours

almost implies that it uses a framework like Rails so I naively blown
these nn chars into this e-mail.

Cheers
