如何在odoo v9中覆盖BaseModel（openerp / models.py）的方法？ [英] How to override method of BaseModel (openerp/models.py) in odoo v9?

问题描述

我想从文件openerp / models.py（line no 1365）中覆盖一个名为'user_has_groups'的函数。我尝试了< a href =https://www.odoo.com/forum/help-1/question/how-to-override-method-of-basemodel-orm-in-odoo-v8-61799 =nofollow noreferrer >这篇文章和这个问题

  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 
  

但它会导致以下错误。 p>

  TypeError：my_user_has_groups（）至少需要4个参数（给出2个）
  

并且我尝试了这一行

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

它会导致以下错误：

  QWebException ：< lambda>（）为关键字参数'groups'获得了多个值
  

from 这篇文章。但它不起作用。

我怎么能做到这一点？请赐教。

解决方案

我用另一种方式解决了这个问题，在下面给出

 来自openerp导入模型，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）
  

I want to override a function called 'user_has_groups' in the class from the file openerp/models.py (line no 1365)

I tried the code from this post and this question

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

But it results the following error.

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

and also i tried this line

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

It results the following error

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

I also tried the code from this post. But it doesn't work.

How I can achieve this? Please enlighten me.

解决方案

I solved this in another way around, which is given below

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)
