Show duration (in minutes) to hours

Question

I want to display the duration of a movie. Right now the movie.duration is shown in minutes (integer)

%b Duration: #{ @movie.duration } # 134 mins

Does rails have a time helper to show this is in a more human-readable way? Something like this:

Duration: 2h 23min

Answer 1

distance_of_time_in_words might help you.

You can use it like this:

distance_of_time_in_words(0, 143.minutes)
# => "about 2 hours"

To use an integer / float you'd need to convert to seconds manually:

distance_of_time_in_words(0, 143 * 60)

You could also calculate it like this:

"#{@movie.duration/60}h #{@movie.duration % 60}min"

The division will give you the hours, while the modulo will give you the minutes.

Finally, for the format specified in your question, there's a Gist you can use for the code here.
