I'm trying to formulate the following fields:

Fields are as follows:

Date_one

Date_two

Int_one (input the number of days)

date_total

Here's the computation:

date_total = (Date_two - Date_one) + 1 - Int_one

How should I do this here? and what are the dependents?

for record in self:
  record['size'] = len(record.name)

Thank you in advance!

Hi Neil,

Try,

today = datetime.date.today()
xmasday = datetime.date(2022, 12, 25)
no_of_days = 5
total_days = (xmasday - today).days + 1 - no_of_days

Hope it helps,

Hi Kiran,

I am getting this error:
ValueError: <class 'TypeError'>: "unsupported operand type(s) for -: 'datetime.date' and 'bool'" while evaluating

its because one of the date fields does not contain any values, So it returns False ,

if today and xmasday:
total_days = (xmasday - today).days + 1 - no_of_days
else:
raise UserError(_('Update Date Field'))

Assuming you are using computed fields:

record ['date_total'] = record.date_two - datetime.timedelta(days=record.date_one + record.int_one - 1)

Add an 'if' statement if there is an error when creating new records. (if the dates are custom their default value 'None' which can't be computed)

The dependencies are fields which trigger the recomputation when changed, so that will be specific to your scenario.

- I am not a programmer so the above code can likely be improved. Hopefully someone else can help here?
