I think I’ve written code to do this at least 3 times, so today I tried to do it right. Let’s say you have a Rails model with a couple dates (any event with beginning and end will do). You generally want to make sure it ends after it begins.
If you try to set end_time before begin_time, you’ll get an error like:
1 errors prohibited this event from being saved
There were problems with the following fields:
- End time is not in chronological order
It will handle more than 2 fields and is configurable as you’d expect.
Grab the code, which is now part of a plugin we’ll talk about more in the next few weeks.
