Question

我想创建一个在用户输入无效日期时引发错误的函数，所以如果我们在当前日期之前输入一个日期，它会显示错误，有什么想法吗？

我的班级看起来像：

class business_trip(orm.Model):
_columns = {'start_trip': fields.datetime('Trip Starts on:',translate=True, required=False),
        'start_business': fields.datetime('Business Starts on:',translate=True, required=False),
        'end_business': fields.datetime('Business Ends on:',translate=True, required=False),
        'end_trip': fields.datetime('Trip Ends on:',translate=True, required=False),

Answer 1

您可以添加添加Python约束，例如

@api.one
@api.constrains('start_trip', 'start_business', 'end_business', 'end_trip')
def _check_date(self):
    now = datetime.now().strftime(DEFAULT_SERVER_DATETIME_FORMAT)
    if self.start_trip and  now < self.start_trip:
        raise exceptions.ValidationError("Entered Date Should be greter then Today")
    elif self.start_business and now < self.start_business:
        raise exceptions.ValidationError("Entered Date Should be greter then Today")
    elif self.end_business and now < self.end_business:
        raise exceptions.ValidationError("Entered Date Should be greter then Today")
    elif self.end_trip and now < self.end_trip:
        raise exceptions.ValidationError("Entered Date Should be greter then Today")

谢谢大家，这是我的解决方案：

<canvas ng-if="render"> </canvas>
