Hi: I want to find the difference between two dates ("project.task" model fields like "repeat_until" and "date_deadline", because subtracting the two dates doesn't work and using .days doesn't work.

Somebody help me. This is when we add a field in a model and I add validations to it.


Thanks

d1 = datetime.strptime(from_date, fmt)
d2 = datetime.strptime(to_date, fmt)
daysDiff = str((d2-d1).days)          -> will gives you 29 days

Hello,

        Can you be more specific..? Doesn't work in the sense? Please post your fields defined in your model and your code which doesn't work.
