Python UnboundLocalError：局部变量'；上下文'；分配前参考-奥多夫8至奥多夫10社区

我有一个从v8迁移到v10社区的方法：

@api.model
def create(self, vals):
    """ To create a new record,
    adds a Boolean field to true
    indicates that the partner is a company
    """
    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，它向我抛出：

我已将

context=context{}

更改为

context=dict（context或{}）

，尽管我不确定是否需要它

有什么想法吗？

只有您自己才能访问上下文。\u context或self.env.context。但是在这里，我认为您的定义是错误的

只有您自己才能访问上下文。_context或self.env.context。但在这里，我认为您的定义是错误的

您可以使用以下语法编写create&write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super方法

使用self.\u context您将获得context，默认情况下context是frozendict。你必须用字典转换，否则你会出错的

当您使用with_上下文调用超级方法时，此时您必须传递现有上下文，而其他wise超级方法将不会获得所有子方法上下文
