Get the values of one2many field

Question

In sales application, when creating a new quotation I am entering a specific pricelist and when I add a product the unit price is automatically updated to match the pricelist. I want to add a new feature where I check if the unit price is less than the price list (unit price changed manually) then I will request admin approval. How can I access the unit price in the one2many field here. Any help please?

You can inherit the sales order lines model in the sales module and make a method with any of Odoo api decorations for example. @api.constrains or @api.onchange to notify the user with a ValidationError if he is not allowed to change the price
Example:
class SalesOrderLines(models.model):
_inherit = 'sale.order.line'
@api.constrains('unit_price')
def _const_price(self):
#your condition and raise ValidationError
