TypeError: write() got an unexpected keyword argument 'context' - Odoo v8 to Odoo v10 community

Question

I've inherited res.partner class, and I have these two methods:

jour_id = fields.Many2one('account.journal', string='Journal', required=False,
    help="Default journal for damaged invoices")
acc_id = fields.Many2one('account.account', string='Account', 
    help="Default account used for invoices and lines from damaged invoices")
printer_fiscal = fields.Boolean(string='Manages fiscal printer',
    help='Indicates that the company can operate a fiscal printer')

@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 = {}
    ctx = self._context.copy()
    ctx.update({'create_company': True})
    return super(ResCompany, self).create(vals) 

@api.model
def write(self, values): 
    """ To write a new record,
    adds a Boolean field to true
    indicates that the partner is a company
    """
    #if context is None:
        #context = {}
    ctx = self._context.copy()
    ctx.update({'create_company': True})
    return super(ResCompany, self).write(values)

These two fields, are updated or created by these two functions create and write.

But when I try any of these, by editing the company, it throws me this:

TypeError: write() got an unexpected keyword argument 'context'

I think it's because of this ctx = self._context.copy() but I've seen other methods on v10 which have it declared this way, I don't know if I should remove it.

Any ideas on this?

You need to use @api.multi decorator in write method.

@api.multi
def write(self, values): 
    """ To write a new record,
    adds a Boolean field to true
    indicates that the partner is a company
    """
    #if context is None:
        #context = {}
    ctx = dict(self._context or {})
    ctx.update({'create_company': True})
    return super(ResCompany, self.with_context(ctx)).write(values)

Here 'Self' is a recordset you can't use @api.one in write method.

You can find difference between 2 decorators from below link.
