Should we replace get_field_by_name() by get_field()

[NhaTrang]

Hi,

I am trying to upgrade this app. I`ve got one error when trying to create an invoice or bill:

Environment:
Request Method: GET
Request URL: http://127.0.0.1:8000/accounts/invoice/create/

Django Version: 3.0.7
Python Version: 3.8.3

Traceback (most recent call last):

    raise TypeError("Invalid argument for include_parents: %s" % (include_parents,))

Exception Type: TypeError at /accounts/invoice/create/
Exception Value: Invalid argument for include_parents: number

Ive replaced get_field_by_name('client')byget_field('client'). Its just the beginning of many others issues but any idea on how to resolve this error please?
