Question

我想从文件openerp / models.py（第1365行）覆盖类中名为'user_has_groups'的函数

中的代码

from openerp.models import BaseModel
def my_user_has_groups(self, cr, uid, groups, context=None):
    #my code

BaseModel.user_has_groups = my_user_has_groups

但是会导致以下错误。

TypeError: my_user_has_groups() takes at least 4 arguments (2 given)

我也试过这行

BaseModel.user_has_groups = lambda cr, uid, groups, context: my_user_has_groups(cr, uid, groups, context)

导致以下错误

QWebException: <lambda>() got multiple values for keyword argument 'groups'

我还尝试了this post的代码。但它不起作用。

我怎么能做到这一点？请赐教。

我用另一种方式解决了这个问题，见下文

from openerp import models, api
class BaseModelExtend(models.AbstractModel):
   _name = 'basemodel.extend'

   def _register_hook(self, cr):            
      @api.cr_uid_context
      def user_has_groups(self, cr, uid, groups, context=None):
         #My code
      models.BaseModel.user_has_groups = user_has_groups
      return super(BaseModelExtend, self)._register_hook(cr)

Answer 2

from openerp.models import BaseModel,api

@api.guess
def my_user_has_groups(self, cr, uid, groups, context=None):
    # your code

BaseModel.user_has_groups = my_user_has_groups

如何在odoo v9中覆盖BaseModel（openerp / models.py）的方法？
