Rails timestamps, See how much time passed since last time

In my app I want to print out the duration of time I spent from I made the model until I updated it.

So if I have the value

:created_at set to 2016-04-13 14:00:49 UTC and :updated_at set to 2016-04-13 15:05:49 UTC

I want to print out that it took 1hour and 5minutes. (or just 01.05). How do I do this?

You can try this

 diff [email protected]_at.to_time.to_i - @object.created_at.to_time.to_i
    hour = "#{diff / 3600}:#{(diff % 3600) / 60}"

I'm not sure why this was downvoted, though a little googling would probably have gotten you to the right answer fairly quickly.

What you're looking for is called time_ago_in_words

Here is the doc http://apidock.com/rails/ActionView/Helpers/DateHelper/time_ago_in_words

And usage is:

time_ago_in_words @object.created_at
time_ago_in_words @object.updated_at

If you want to use it the console to play with it, make sure you preface it with helper so it's loaded into console

e.g.

helper.time_ago_in_words @object.created_at

update

For checking between 2 dates, not just one date from right now, then you can use distance_of_time_in_words

distance_of_time_in_words(@object.created_at, @object.updated_at)

That gives words like

12 days ago

If you're ONLY looking for hours, and nothing else then you can use basic subtraction and division

@object.updated_at.to_i - @object.created_at.to_i) / 60 / 60
