Python 单击自定义模块添加的新按钮时的AttributeError

我试图通过自定义模块在res.partner表单视图（base.view\u partner\u表单）上添加一个新按钮，以打开新的浏览器选项卡，但出现以下错误：

    Traceback (most recent call last):
  File "/opt/odoo/odoo-server/openerp/http.py", line 540, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)

    return getattr(request.registry.get(model), method)(request.cr, request.uid, *args, **kwargs)
AttributeError: 'res.partner' object has no attribute 'g_search'

按钮出现了，但是我被这个错误卡住了。以下是我的文件内容：

非常感谢您的帮助

注意。

您已经导入了导入cant\u neg\u gs类名，但必须导入文件。名称不是类名Ex-：导入mymodule

您的代码中还有一个问题，您可以遵循下面的代码

from openerp import models,fields,api
class res_partner(models.Model):
    _inherit="res.partner"

    @api.multi
    def g_search(self):
        res = {
            'type': 'ir.actions.act_url',
            'url': 'http://www.myurl.com',
            'target': 'new',
        } 
        return res

在您的文件中，未导入api，您使用了@api.multi，这就是您必须导入api的原因

这可能对你有帮助
