groupedFor-根据日期对对象进行分组 [英] groupedFor - grouping objects according to dates

问题描述

以下代码不会根据约会日期对我的约会进行分组.属性date是DateTime对象(时间戳).

The below code won't group my appointments according to the appointment-dates. The property date is a DateTime object (timestamp).

<f:groupedFor each="{appointments}" as="appointmentofdate" groupBy="date" groupKey="groupdate">

  {groupdate}:
  <br>
        <f:for each="{appointmentofdate}" as="appointment">

           {appointment.name} <br>
           {appointment.contact}

        </f:for>
        <hr>

</f:groupedFor>

尝试将日期格式化为"d.m"格式也无法解决问题:

Trying to format the date to the form "d.m" also didn't solve the issue:

<f:groupedFor each="{appointments}" as="appointmentofdate" groupBy="{f:format.date(date: date, format: 'd.m')}" groupKey="groupdate">

  {groupdate}:
  <br>
        <f:for each="{appointmentofdate}" as="appointment">

           {appointment.name} <br>
           {appointment.contact}

        </f:for>
        <hr>

</f:groupedFor>

我如何根据约会将所有约会分组?

我想要输出:

02.09:
appointmentname1
Jerry Maier

appointmentname2
Esther Tannbaum

appointmentname3
Johnny Free
_____________________________________________
06.09:

appointmentname4
Otto Kringel

推荐答案

您的模型中需要额外的吸气剂.重命名字段

You need an additional getter in your model. Rename the field

/**
 * Get day of datetime
 *
 * @return int
 */
public function getDayOfDatetime()
{
    return (int)$this->date->format('d');
}

然后可以将其用于分组{appointments.dayOfDatetime}

This can be used then for grouping {appointments.dayOfDatetime}
