Hi,
As I've said before, I created the same new fields on account_tax and
account_invoice_tax. I created a new tax and filled those fields.
What I want is: when I insert a new product on a invoice those fields
must to be filled with the same information that was registered when
I configured the tax of this product.
To get this I need to modify Invoice._compute_tax.
Invoice._compute_tax is static. But I need to override this method to
include the new fields. How can I do?
You can see all staticmethod as classmethod which don't need in the
code the cls, so you can override them using a classmethod.
This way I'll have to copy the method to my module and modify it, right?
Because when I try to do:
@classmethod
def _compute_tax(cls, invoice_tax, invoice_type):
super(Invoice)._compute_tax(invoice_tax, invoice_type)
It gives me the error: AttributeError: 'super' object has no
attribute '_compute_tax'
It must be:
@classmethod
def _compute_tax(cls, invoice_tax, invoice_type):
super(Invoice, cls)._compute_tax(invoice_tax, invoice_type)
Ok.
May you please answer this question?
1. When I do a new module and I want to change something in a core
module I create a file with the same name as the core. This is
considered a inheritance or partial class?
If partial class (I don´t know if it exists on Python) Tryton do a mixin
and replaces the conflicts names with the names of the second class?
Thank you,
