Calling field in method of another object

inherit self objects self.env.search

MatheusF

I created a field of type Boolean 'check_barcode' in the stock.config.settings object. The intent of this field is as follows if it is marked as true it would have entered a method that is in another inherited object. The problem is that my self.env is not bringing the check_barcode field (I think it's not making the stay).

How to call the check_barcode field in the def calculate_checksum method?

field.py

class StockSettings(models.TransientModel):

_inherit = 'stock.config.settings'

check_barcode = fields.Boolean(string='check_barcode')

product.py

class ProductTemplate(models.Model):

_inherit = "product.template"

@api.onchange('barcode')

def calculate_checksum(self):

#if self.env.user.company_id.product_ids.compute(self.company_id.check_barcode, self.product_ids):

#if self.env['res.config.settings'].check_barcode: #.company_id.product_ids.compute(self.company_id.check_barcode, self.product_ids):

if self.check_barcode == 'True':

if self.barcode:

barcode = self.barcode[:12]

if len(barcode) < 12:

barcode = barcode.ljust(12, '0')

sum_ = lambda x, y: int(x) + int(y)

evensum = reduce(sum_, barcode[::2])

oddsum = reduce(sum_, barcode[1::2])

digit = (10 - ((evensum + oddsum * 3) % 10)) % 10

self.write(

{

'barcode': barcode + str(digit)

}

)

else:

return False

Hi,

You can update your field.py file like this,

class StockSettings(models.TransientModel):
    _inherit = 'stock.config.settings'

    check_barcode = fields.Boolean(string='check_barcode')
    
    @api.multi
    def set_check_barcode(self):
        """ saving the values to ir.values """
        IrValues = self.env['ir.values']
        IrValues.set_default('stock.config.settings', 'check_barcode', self.check_barcode)

Then in the calculate_checksum function, you can get the value of the check_barcode like this,

ir_values = self.env['ir.values']
check_barcode = ir_values.get_default('stock.config.settings', 'check_barcode')

Now your code will be like this,

class ProductTemplate(models.Model):
    _inherit = "product.template"

    @api.onchange('barcode')
    def calculate_checksum(self):
        ir_values = self.env['ir.values']
        check_barcode = ir_values.get_default('stock.config.settings', 'check_barcode')
