product.template

Hello everybody!

I have created 2 classes which are really similar:
class A(models.Model):
    _name = 'product.template'
    _inherit = 'product.template'
    file = fields.Binary(_('File'), required=False)
   
class B(models.Model):
    _name = "product.template"
    _inherit = 'product.template'
....   
...
my_file = self.env['product.template'].file

I want to access the file field of class A from class B but I always get value none/False eventhough i have a file uploaded. I tried with other custom fields also but what I get is nothing.
Is there a way to access fields from the other classes of the inherited product.template?


Thanks a lot in advance!

Because both of your models are inheriting the same base model, your initial field, file, will already exist and can be accessed through the file field in model B.

If you want to duplicate the file onto another field you may want to try assigning a default: 

my_file = fields.Binary(....... default=self.file)

I don't think you really need self.env['product.template'] here, it should probably just look like my_file = self.file

Thank you for your answer.

That was the first what i have tried, but i still get the none/False eventhough i have a file uploaded. I tried also to inherit class B from class A, still no effect.
I may have to read it directly from database?!
