Actually i test it in my system and working fine, so can you please show the screen shot of the error. and the python code too.

put

print(a)

print(type(a))

before

s.total_days = a.days

show the result to us.

Here is my python code

depature_date = fields.Date(string="Depature Date From Work", required=True)

return_date = fields.Date(string="Return Date To Work", required=True)

total_number_of_days = fields.Integer(compute="_compute_days",string="Total Number Of Work Days", copy=False, default=0, store=True)

@api.multi

@api.depends('depature_date','return_date')

def _compute_days(self):

for s in self:

if s.depature_date and s.return_date:

a = s.depature_date + s.return_date

s.total_number_of_days = a.days

else:

s.total_number_of_days = 0

here is the error message

s.total_number_of_days = a.days

AttributeError: 'str' object has no attribute 'days'

a = s.depature_date + s.return_date

why you are adding?

what is your logic? can you explain what is your exact need?

I'm adding depature_date and return_date to get the total_number_of_days .

Hello NIKHIL KRISHNAN,

The logic is once depature_date and return_date is selected automatically the total_number_of_days should be counted as total days selected.

I'm this ways i want to add depature_date + return_date to get the total days.

ok fine,

You try with this code.

a = s.return_date - s.depature_date

s.total_number_of_days = a.days

if we add two dates, we can't get a total number of days, differece of dates means the number of days between the two dates. i think you got the idea.

upvotes are appreciated

NIKHIL KRISHNAN ,

I have try this code and get error

a = s.return_date - s.depature_date

s.total_number_of_days = a.days

Error Message

in _compute_days

a = s.depature_date - s.return_date

TypeError: unsupported operand type(s) for -: 'str' and 'str'

please convert them in to date formate.
