Hi,

I'm tring to update sale order line once Unit Price field changed but constraints does not run.

here my code

class SaleOrderLine(models.Model):
    _inherit = 'sale.order.line'

    @api.constrains('price_unit')
    def _check_price_unit(self):
        for line in self:
            product = line.product_id
            standard_price = product.standard_price            
            if line.price_unit < 250
                line.price_unit = min_price

Can you help me about this?

Constraint is needed to forbid applying a certain change. So, you can raise some error or warning, but should not use it to change a wrong value. E.g.:

from odoo.exceptions import UserError

class SaleOrderLine(models.Model):
    _inherit = 'sale.order.line'

    @api.constrains('price_unit')
    def _check_price_unit(self):
        for line in self:
            product = line.product_id
            standard_price = product.standard_price            
            if line.price_unit < 250
                raise UserError(_("The price migth be not less than 250"))

If you want to apply changes based on entered values, you should either use inverse or re-write CRUD methods write / create.
