Question

这是Odoo中的以下代码，并不像我预期的那样工作。

 def _check_dates(self, cr, uid, ids, context=None):    
    for rec in self.browse(cr, uid, ids, context=context):
        if rec.rdate and rec.gdate :
        start = date.strftime(str(rec.rdate), "%Y-%m-%d")
        end = date.strftime(str(rec.gdate), "%Y-%m-%d")
        if start >= end:
                return False
    return True

    _constraints = [
        (_check_dates, 'Error ! Received Date must be less or equal than given Date', ['rdate'])
        ]

请纠正我的任何人。感谢

使用新的Odoo 8 ORM API（无需向_constraints列表中添加任何内容（现已弃用）：

@api.one
@api.constrains('rdate', 'gdate')
def _check_dates(self):
    if self.rdate and self.gdate:
        start = fields.Date.from_string(self.rdate)
        end = fields.Date.from_string(self.gdate)
        if start > end:
            raise exceptions.ValidationError("Error! Received Date must be less or equal than given Date")

注意：我将start >= end更改为start > end，使其与您的错误消息一致（因为之前的代码不接受相同的日期）。

或者，您可以将其设置为SQL约束，这样可以在更深层的数据库级别上进行操作：

_sql_constraints = [
    (
        'rdate_gdate_check',
        'check(rdate <= gdate)',
        "Error! Received Date must be less or equal than given Date",
    ),
]

请在Odoo中使用以下代码更正我
