Hi all:

  I'm trying to change res_partner.py and wanna add some fields in it,but when I restart my pycharm,when I clicked any module,it warns me:

Odoo Server Error

Traceback (most recent call last):
File "D:\odoo\test_1\odoo\api.py", line 1039, in get
value = self._data[key][field][record._ids[0]]

  So is there a correct way to change base module?

  Thanks
