setting up constraint on start_date and deadline

I added two fields to project module, start_date and stop_date. And I tried to add a code that controls the input and only saves the record if stop_date is greater than start_date. So I added this code to the project class:

    date_start = fields.Date(string='Start Date')
    date_stop = fields.Date(string= 'Deadline')
    @api.onchange('date_stop')
    def _onchange_date_stop(self):
    if self.date_start != False and self.date_stop != False:
        if (self.date_stop<=self.date_start):
            raise ValidationError("deadline date Should be greater than start date!")
    _constraints = [
    (_onchange_date_stop, 'deadline date 2 Should be greater than start date!', []),
]

Now when the deadline is before the start date, it raises validation error:

    deadline date Should be greater than start date!

and when I try to save the record I got this error:

    deadline date 2 Should be greater than start date!

    Error details:
    deadline date Should be greater than start date!
    None

But when the deadline is greater than the start date, I got this error:

    deadline date 2 Should be greater than start date!

So I always have a problem, whether if the deadline was greater or not than the start date.

Anybody can help? Thanks.

Other than onchange we can use constraints... It helps to validate something when create and edit and also in change.. Here is my code and it works fine

date_start = fields.Date(string='Start Date')
date_stop = fields.Date(string= 'Deadline')

@api.multi
@api.constrains('date_start', 'date_stop')
def _check_date(self):
    date_start = self.date_start
    date_stop = self.date_stop

    if (date_start and date_stop) and (date_start > date_stop):
        raise ValidationError(_('The start date must be less than to the end date. ')

Also this code worked for me too:

    date_start = fields.Date(string='Start Date')
    date_stop = fields.Date(string= 'Deadline')

    @api.one
    @api.constrains('date_start', 'date_stop')
    def _check_deadline(self):
        if self.date_stop <= self.date_start:
            raise ValidationError("deadline must be greater than start date")

You can use constrain decorator

@api.constrains('date_start', 'date_stop')
def check_date_fields(self):
    if self.date_start and self.date_stop:
        if self.date_stop <= self.date_start:
            raise ValidationError("deadline date Should be greater than start date!")
