Question

我有这种方法，我已经从v8迁移到v10社区：

@api.model
def create(self, vals):
    """ To create a new record,
    adds a Boolean field to true
    indicates that the partner is a company
    """
    if context is None:
        context = {}
    context.update({'create_company': True})
    return super(ResUsers, self).create(vals) 

@api.multi
def write(self, values): 
    """ To write a new record,
    adds a Boolean field to true
    indicates that the partner is a company
    """
    context = dict(context or {})
    context.update({'create_company': True})
    return super(ResUsers, self).write(values)

当我点击这些布尔值时，它会抛出这个：

我已将context = context {}更改为context = dict(context or {})，但我不确定是否需要它。

有什么想法吗？

Answer 1

只有您可以通过self._context或self.env.context访问上下文。但在这里我认为你错误地定义了

Answer 2

你可以写创作＆amp;使用以下语法编写方法。

@api.model
def create(self, vals):
    """ To create a new record,
    adds a Boolean field to true
    indicates that the partner is a company
    """
    context=dict(self._context or {})
    context.update({'create_company': True})
    return super(ResUsers, self.with_context(context)).create(vals)

@api.multi
def write(self, values): 
    """ To write a new record,
    adds a Boolean field to true
    indicates that the partner is a company
    """
    context=dict(self._context or {})
    context.update({'create_company': True})
    return super(ResUsers, self.with_context(context)).write(vals)

使用with_context可以将上下文传递给超级方法

使用self._context，您将获得上下文，默认情况下，上下文为frozendict。你必须转换为dict，否则你会得到错误。

当你使用with_context调用super方法时，那时你必须传递现有的上下文以及其他明智的超级方法将不会获得所有子方法上下文。
