Hi,

Constraints are the rules specified on a record that prevent incorrect data before saving the record. Python constraints are used for the validation process. The validation function will be triggered whenever the validating fields are modified, and then it should raise an exception. Usually, the ‘ValidationError’ is used to show the exception
  from odoo import api, fields, models, _
  class ProductTemplate(models.Model):  

  _inherit = "product.template"
    minimum_amount = fields.Float('Minimum Order Amount')
class SaleOrderLine(models.Model):  

 _inherit = 'sale.order.line'
     @api.constrains('price_subtotal')def _check_price_subtotal(self):
    for record in self:
        if record.price_subtotal > record.product_id.product_tmpl_id.minimum_amount:
            raise ValidationError(_( "Minimum order amount of the product ")
For more details, refer to the book:
