I need to calculate the difference between two dates : 

py :

start_date = field.Date()

end_date = field.Date()

xml :

<field name="start_date"/>

<field name="end_date"/>

Hello Yassin,

Try something like this from your python file.

You can call the function in different ways.

Check an example from Button Click.

from datetime import datetime


class YourClass(models.Model):
    _inherit = 'your.model'

    @api.multi
    def your_function(self):
        fmt = '%Y-%m-%d'
        start_date = self.start_date
        end_date = self.end_date
        d1 = datetime.strptime(start_date, fmt)
        d2 = datetime.strptime(end_date, fmt)
        date_difference = d2 - d1


Thanks & Regards

hi Avinash, thanks for your answer

I try to call the function in a compute filds and display the result but it doesn't work this is my code, it dispays 0 :

...

class EcoStage(models.Model):

name =eco.stage

start_date = fields.Date()

end_date = fields.Date()

duree_stage = fields.Integer(string="duree stage", compute='difference_date', store=True)

@api.multi

def difference_date(self):

fmt = '%Y-%m-%d'

start_date = self.start_date

end_date = self.end_date

d1 = datetime.strptime(start_date, fmt)

d2 = datetime.strptime(end_date, fmt)

date_difference = d2 - d1

in xml :

<fields name="duree_stage "/>

Avinash Nk

Add the 2 fields in the dependency.

---> @api.depends('start_date', 'end_date')

Avinash Nk

Also d2-d1 not gives an integer value.

So do like this. (d2 - d1).days

Avinash Nk

And assign the difference value in the computed field.

Like this. self.duree_stage = (d2 - d1).days

It can be done easily in odoo 14:

start_date = fields.Date(string="Start date")
end_date = fields.Date(string="End date")
date_diff = fields.Char("Date difference")

@api.constrains('start_date', 'end_date', 'date_diff')
def _date_difference(self):
    for record in self:
        if record.start_date > record.end_date:
            raise ValidationError('Start date should not greater than end date.')
        else:
            record.date_diff = (record.end_date - record.start_date).days

finally it works 

thanks a lot Avinash you save my life

this is the entier final code :

in .py:

...

class EcoStage(models.Model):

_name ='eco.stage'

start_date = fields.Date()

end_date = fields.Date()

duree_stage = fields.Integer(string="duree stage", compute='difference_date', store=True)

@api.multi

@api.depends('  start_date ',' end_date ')

def difference_date(self):

fmt = '%Y-%m-%d'

start_date = self.start_date

end_date = self.end_date

d1 = datetime.strptime(start_date, fmt)

d2 = datetime.strptime(end_date, fmt)

if d2 >d1 :

self.  duree_stage = (d2 - d1).days

else :

raise ValueError('end date should be superior than start day')

...

in xml :

<fields name="duree_stage "/>
