Hi Wimpy,

Write a constraint for the purchase price that prevents records with a purchase value less than or equal to zero.

@api.constrains('purchase_price')
def _check_purchase_price(self):
    for record in self:
        if record.purchase_price <= 0:
            raise ValidationError("Purchase price must be greater than 0.")

Hope it helps,
Kiran K

Hi,

In this case you have an option to set the value of the field default as 1

example:

from odoo import models, fields

class YourModel(models.Model):

    _inherit = 'your.model'

    your_float_field = fields.Float(string='Your Float Field', default=1.0)

OR

You can add a validation to it

from odoo import models, fields, api

from odoo.exceptions import ValidationError

class YourModel(models.Model):

    _inherit = 'your.model'

    your_float_field = fields.Float(string='Your Float Field')

    @api.constrains('your_float_field')

    def _check_minimum_value(self):

        for record in self:

            if record.your_float_field

                raise ValidationError("The value of 'Your Float Field' must be at least 1.")
