Question

我有一个名为worker的实体的日期间隔，有一段时间看下一个函数：

// Get date of retirement
public function getRetireYear()
{
    $this->retireYear = $this->getBirthDay()->add(new \DateInterval('P60Y'));
    return $this->retireYear;
}

// Get time left for retirement
public function getTimeToRetirement()
{
    // Date of today
    $today = new \DateTime('today');

    // Calculate date diff between today and retirement day.
    $this->timeToRetirement = $today->diff($this->retireYear);

    // Return the time to retirement time formated
    return $this->formatTimeInterval(
        $this->timeToRetirement,
        '%r%Y years, %m months, %d days'
    );
}

//Format the dateInterval numbers as string
public function formatTimeInterval($aDateDif, $format)
{
    return $aDateDif->format($format);
}

此处存储在数据库中的唯一值是$this->getBirthDay()，然后getRetireYear生成工人退休年份（birthDay + 60年）。
getTimeToRetirement给出了退休某人的时间，formatTimeInterval($,$)用于格式化日期间隔。

现在我需要能够以不同的格式使用这个dateInterval，例如有时我只需要将年份作为整数与视图中的其他值进行比较，所以我需要今年作为单个值才能在视图。

我尝试了一些事情，但我不知道正确的方法，所以我没有得到更好的结论。

有时我需要其他任务的月份和日期，而不仅仅是年份，这些值应该可以在视图上访问，因为在控制器中我只是搜索对象的ArrayColletion并将其传递给视图，否则我必须上升并降低阵列集合。

Answer 1

我认为最好让getTimeToRetirement方法返回DateInterval并将formatTimeInterval方法完全移出实体，因为它与DateInterval更相关格式化而不是你的工人。然后，您可以根据需要格式化DateInterval。这些方面的东西。

在您的工作组实体类中：

// Get date of retirement
public function getRetireYear()
{
    $this->retireYear = $this->getBirthDay()->add(new \DateInterval('P60Y'));
    return $this->retireYear;
}

// Get time left for retirement
public function getTimeToRetirement()
{
    // Date of today
    $today = new \DateTime('today');

    // Calculate date diff between today and retirement day.
    $this->timeToRetirement = $today->diff($this->retireYear);

    // Return the time to retirement time as a DateInterval
    return $this->timeToRetirement;
}

然后，您可以使用date Twig过滤器格式化视图中的DateInterval。见http://twig.sensiolabs.org/doc/filters/date.html 如果您需要更具体或封装的内容，您还可以为此创建一个Twig扩展。见http://symfony.com/doc/master/cookbook/templating/twig_extension.html

这就是我所做的，但可能不是最实用的方式：

    public function getYearsLeft(){
    $aux = $this->birthDay->add(new \DateInterval('P60Y'));       
    //date today
    $today = new \DateTime('today');
    // Calculate date diff between today and retirement day.
    $this->yearsLeft = $today->diff($aux);                
    $aux2 = $this->formatTimeInterval($this->yearsLeft, '%r%Y');
    $this->birthDay->sub(new \DateInterval('P60Y'));
    return $aux2;
}
public function getMonthsLetf(){
    $aux = $this->birthDay->add(new \DateInterval('P60Y'));       
    //date today
    $today = new \DateTime('today');
    // Calculate date diff between today and retirement day.
    $this->monthsLetf = $today->diff($aux);        
    //$this->yearsLeft = $aDateDif; //('%r%Y');
    $aux2 = $this->formatTimeInterval($this->monthsLetf, '%m');
    $this->birthDay->sub(new \DateInterval('P60Y'));
    return $aux2;
}

我将在3个函数中转换这两个函数更简单，更可重用，如果我需要从这个环境外部创建帮助器。在Controller中我访问配置文件：

         $redTime = $this->container->getParameter('time_red');
         $orangeTime = $this->container->getParameter('time_orange');

当然，我不必将工作者列表传递给视图以及配置变量。现在在视图中我可以按如下方式访问变量：

                {% for aWorker in aWorkerList %}
            {% if aWorker.retireYear is defined %}
              {% if colorOrange > aWorker.yearsLeft %}
                  <tr bgcolor="orange">
                  {% if colorRed > aWorker.monthsLetf %}
                        <tr bgcolor="red">                                
                        {% elseif 0 > aWorker.yearsLeft %}
                                <tr bgcolor="red">                                    
                  {% endif %}                  

              {% endif %}
                        <td><a href="{{path('osd_retire_editworkerpage', { 'id': aWorker.idWorker })}}">Edit</a> 
                            <a href="{{path('osd_retire_deleteworkerpage', { 'id': aWorker.idWorker })}}">Delete</a></td> 
                        <td>{{aWorker.omang}}</td>                        
                        <td>{{aWorker.workerTitle}}</td>
                        <td>{{aWorker.workerName}}</td>
                        <td>{{aWorker.workerSurname}}</td>
                        <td>{{aWorker.birthDay|date('Y-m-d')}}</td>
                        <td>{{aWorker.dateOfEmployment|date('Y-m-d')}}</td>
                        <td>{{aWorker.retireYear|date('Y-m-d')}}</td>
                        <td>{{aWorker.timeToRetirement}}</td>
                        <td>{{aWorker.fileNumber}}</td>
                    </tr>
            {% endif %}
            {% endfor %}

它的工作正常......违反哲学的独立性！？
