Is there any way to identify from an api.constrain if the change comes from the UI? (Odoo 14)

I would like to determine whether the constraint has been triggered due to a user-initiated change from the Odoo UI or if it has been triggered from within the internal code of another application.


The code would be something like that:


​class StockMove(models.Model):
_inherit = "stock.move"

​@api.constrains('sequence')
​def _constrains_sequence(self):
​​if comes_from_UI:
​ ​ ​raise ValidationError(_("Not allowed to change the sequence of moves from the picking."))

Hey, 


Maybe you can write onchange it will fit your needs.

Thanks

Hi Jay,

Thank you for your response. However, from my understanding, the onchange methods are executed not only when modifying values from the UI but also when modifying them from the code.

So, I would encounter the same issue while attempting to differentiate whether that change originates from a UI modification.

The operation cannot be completed: another model requires the record being deleted. If possible, archive it instead. Model: product.enquiry (product.enquiry), Constraint: product_enquiry_product_id_fkey
