Hi,

I added a compute field and do the calculation in function through when quantity is 0 or less than 0 popup error message. but when I go back trying to open form view I can't open the because error message comes.

I need to know is there any possibility to pop up an error message when I used to compute field.

Hi Dishan,


Try to write an onchange function instead. So the function will only trigger when the value in your field is changed. Also make sure you add a check to not show the error when there is no value in the field.


@api.onchange('value')
def _onchange_value(self):
if self.value:
if self.value <= 0:
raise UserError("Error")
