Hi, guys. I have a problem in many2one field. So here is my code in model.py
prodname = fields.Many2one('product.template', string='Product Name')
I want to drop down my product list. the problem is, sometimes is success also error. the error is like this
AttributeError: '_unknown' object has no attribute 'id'
In the Technical > Fields, the related model is '_unknown' that is supposed to 'product.template', right?
Please, help me to fix this. Thanks a lot.
Hi!
Could you check that you have added the necessary depends to your __manifest__.py? It is similar as you didn't add the dependency to the "product" module that contains the "product.template" model.
"depends": ["product"],
As a suggestion, the relation field name would be more clearer if it will have the suffix "_id" for Many2one fields and "_ids" for Many2many or One2many fields.

Yes, thank you so much Yurii. I forgot to add the "depends" value. Thank you, it's work.
