How to convert datetime.timedelta to number? Field 'days' expected a number but got datetime.timedelta

Question

My code:

data.days=(form.cleaned_data['checkout'] - form.cleaned_data['checkin'])

The error message:

Field 'days' expected a number but got datetime.timedelta

Answer 1

timedelta has a days property you can use:

data.days = (form.cleaned_data['checkout'] - form.cleaned_data['checkin']).days
# Here -------------------------------------------------------------------^

Answer 2

datetime.timedelta is an object instantiated, besides the standard constructor way, as a result of the difference between two datetime objects. It represents a time duration expressed in days, seconds and microseconds.

timedelta also provides a set of properties to access those values, namely:

timedelta.days
timedelta.seconds
timedelta.microseconds

the first one being the one you're searching for.
