Hi, i´m new to Ruby and have some problems when i´m creating new methods for my application. I read different tutorials and understand the structure (okay, i thought i did ;-)). Now i build my own little application where i have 4 models: the user, book, category and booking. The booking model has among others 2 fields, startdate enddate. I have a list with bookings from a user, where i want show which books he had lend from which category and show the difference between the end and the start-date (not in words, mayby in days or hours). Around this list i have an each do loop. Now i have found different examples to create a method to get the date difference, but i don´t know HOW i have to implent it in my application, WHERE this method has to stand (in the Model or the controller?) and how it has to look in the view. thanks for your help! -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Your view just needs to do <%= display_booking_length booking %> fred> thanks for your help! > > -- > Posted viahttp://www.ruby-forum.com/.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for your help!
The 2 columns in the booking model are end_at and start_at and i need
the difference between these two dates in minutes. In the booking model
i want to do something like this:
booking.rb
def date_diff
minutes = Booking.new
date2 = Time.end_at
date1 = Time.start_at
difference = date2 - date1
minutes = (difference % 3600) / 60
end
booking.controller
???
I´m aware that this method doesn´t work but have problemes to bring it
in the right form. And how does the view helper has to look like?
