I would like to be able to do a date comparison to
return the number of days left until a date (stored in
my database) is reached. I can’t seem to find a ruby
function that will do such an operation
In this case, you’re looking for Rails helper modules, not Ruby methods.
you haven’t already, check out
ActiveSupport::CoreExtensions::Time::Calculations for more of them.
and regardless of this, other ruby functions throw
errors when I try to apply them to this date, e.g.
returns this error:
undefined method `next_week’ for “2007-03-28 18:30:00”:String
next_week works on a Time object and the_event.start_on is apparently a
String object. If you’re intentionally storing it as a String, you
use the to_time conversion before applying the next_week method.
