关于 Odoo 模块从 v8 社区迁移到 v10 社区的疑虑——以及错误

Question

考虑这个方法：

@api.multi
def _get_loc_req(self): #, cr, uid, context=None
    """Get if a field is required or not by a Localization
    @param uid: Integer value of the user
    """
    context = dict(self._context or {})
    res = True
    ru_brw = self.pool.get('res.users').browse(
        self.cr, uid, uid, context=context)
    rc_obj = self.pool.get('res.company')
    rc_brw = rc_obj.browse(self.cr, uid, ru_brw.company_id.id, context=context)

    if rc_brw.country_id and rc_brw.country_id.code == 'VE' and \
            rc_brw.printer_fiscal:
        res = False
    return res

如您所见，我添加了 @api.multi 注释 cr, uid, context=None 因为 multi 应该自动处理这些参数，对吗？

但是例如，如果我运行这段代码，它会抛出这个错误：

self.cr, uid, uid, context=context)
AttributeError: 'account.invoice' object has no attribute 'cr'

在上面的方法中，我按照新的 api 将 cr 更改为 self.cr，但没有成功，同样的错误，例如 self.pool.get不应该是self.env吗？还是可以一直这样？

一般来说，新 API 应该是什么样子？除了装饰器，还有 cr statements?

我还有一个疑问，例如，这些方法可以这样声明：

@api.multi
def my_method(self):
    return

但是如果最初有，cr, uid, ids, context 等，并且这些参数实际上在方法内部，（就像在上面的方法中一样）是否应该替换它们？它应该是什么样子？

我该如何解决这个问题？如果你能解释这些审问者也太棒了！

Answer 1

我觉得你的方法可以写成：

@api.model
def _get_loc_req(self):
    company = self.env.user.company_id
    if (company.country_id and company.country_id.code == 'VE' and
            company.printer_fiscal):
        return False
    return True

关于您的第二个问题 - 在新的 API 中，无需明确传递 cr, uid、ids 和上下文 - cr (self.env.cr)、uid (self.env.user) 和 context (self.env.context) 通过环境 (self.env) 和ids 的概念被替换为 record sets. Odoo 10 does not support the old API (pre version 8), so I would recommend spending some time for getting used to the new API: link, link, link, link. Also, you might take a look at the code of official Odoo addons for version 10.0 - 它们都是使用新的 API.
