Question

我有这个约束：

_constraints = [
    (_unique_invoice_per_partner,
     _('The Document you have been entering for this Partner has already'
       ' been recorded'),
     ['Control Number (nro_ctrl)', 'Reference (reference)']),
]

关于这个领域：

nro_ctrl = fields.Char(
    string='Control Number', size=32, readonly=True, required=True,
    states={'draft': [('readonly', False)]},
    help="Number used to manage pre-printed invoices, by law you will"
         " need to put here this number to be able to declarate on"
         " Fiscal reports correctly.")

如果我创建发票，验证并支付发票（此字段位于account.invoice模型上），则此约束有效。

但是，如果我创建退款，那么它表示没有正确设置字段：

The operation cannot be completed, probably due to the following:
- deletion: you may be trying to delete a record while other records still reference it
- creation/update: a mandatory field is not correctly set

[object with reference: nro_ctrl - nro.ctrl]

我也有这种方法，理论上应该允许＆＃34;复制＆＃34;或复制发票，包括该字段：

@api.multi
def copy(self, default=None):
    """ Allows you to duplicate a record,
    child_ids, nro_ctrl and reference fields are
    cleaned, because they must be unique
    """
    # NOTE: Use argument name ids instead of id for fix the pylint error
    # W0621 Redefining buil-in 'id'
    #if default is None:
        #default = {}
    default = self._context.copy() #default.copy()
    default.update({
        'nro_ctrl': None, 
        'supplier_invoice_number': None,
        'sin_cred': False,
        # No cleaned in this copy because it is related to the previous
        # document, if previous document says so this too
        'date_document': False,
        'invoice_printer': '',
        'fiscal_printer': '',
        # No cleaned in this copy because it is related to the previous
        # document, if previous document says so this too
        # loc_req':False,
        'z_report': '',
    })
    return super(AccountInvoice, self).copy(default)

这是我从v8到v10社区的迁移。

我不知道这种copy方法是否必要。

如何在考虑此约束的情况下创建退款？我的意思是，带着nro_ctrl字段。

有什么想法吗？

Answer 1

您已创建新字段 nro_ctrl ，并且您已在py文件中写入 required = True 。

当您在py文件中必填字段时，数据库表中。

在复制方法中，您正在更新'nro_ctrl'：无。由于这个原因，您在创建时遇到错误，因为没有任何值不允许在必填字段中。

如果发票中需要 nro_ctrl 字段，则您必须在退款的复制方法中提供唯一值。
