Question

如果员工关闭，我正试图在某个字段中隐藏评论。我已将if标记添加到字段本身，但在ifchange循环中，如果员工已启用，则不会看到更改并在字段中添加注释。我将其移到ifchange之上，但如果员工关闭则不会显示任何字段。所以基本上我的检查会跳过第一个（非工作时间）但是if_changed会忽略第二个，因为bar_record是相同的。我无法弄清楚如何工作。非常感谢任何帮助！

更新

我通过将if not foo.is_off移到DOM上来解决这个问题，但我被告知这可能会更短。那是if。

CODE

    {% for foo in bar_information.bar_hours %}
      {% if not foo.is_off %}   <!-- is there a shorter better way of writing this?  -->
      {% ifchanged foo.bar_record %}
      <tr class="{% cycle 'rowEven' 'rowOdd' %}">
        <td>
          {{ foo.bar_record.get_formatted_id }}
        </td>
        <td>
          {{ foo.bar_record.entered_in|date:"DATETIME_FORMAT" }}
        </td>
        <td>
          {{ foo.bar_record.get_display }}
        </td>
        <td>
          {{ foo.bar_record.get_mistake_display }}
        </td>
        <td>
          {% if foo.bar_record.number_shifts %}
            {{ foo.bar_record.number_shifts }}
          {% endif %}
        </td>
        <td>
          <div style="width: 400px; word-wrap: break-word;">
              {{ foo.bar_record.comments }}   <!-- THIS COMMENT IS WHAT I NEED TO HIDE IF EMPLOYEE IS OFF  -->
          </div>
        </td>
        <td align="right">
          <a class="button"
            href="{% url 'bar_record_view' foo.bar_record.pk %}">
                      View Record</a>
          {% has_permission_cust CHECK_COMPLIANCE %}
            {% url 'check_compliance' foo.bar_record.pk as check_compliance_url %}
            <a href="{{ check_compliance_url }}" class="button">Check Compliance</a>
          {% end_has_permission_cust %}
        </td>
      </tr>
      {% endifchanged %}
      {% endif %}
    {% empty %}
    {% endfor %}

我发现将'if not foo.is_off'移动到它工作的DOM上。就这样：

{% for foo in bar_information.bar_hours %}
  {% if not foo.is_off %}   <!-- is there a shorter better way of writing this?  -->
  {% ifchanged foo.bar_record %}
  <tr class="{% cycle 'rowEven' 'rowOdd' %}">
    <td>
      {{ foo.bar_record.get_formatted_id }}
    </td>
    <td>
      {{ foo.bar_record.entered_in|date:"DATETIME_FORMAT" }}
    </td>
    <td>
      {{ foo.bar_record.get_display }}
    </td>
    <td>
      {{ foo.bar_record.get_mistake_display }}
    </td>
    <td>
      {% if foo.bar_record.number_shifts %}
        {{ foo.bar_record.number_shifts }}
      {% endif %}
    </td>
    <td>
      <div style="width: 400px; word-wrap: break-word;">
          {{ foo.bar_record.comments }}   <!-- THIS COMMENT IS WHAT I NEED TO HIDE IF EMPLOYEE IS OFF  -->
      </div>
    </td>
    <td align="right">
      <a class="button"
        href="{% url 'bar_record_view' foo.bar_record.pk %}">
                  View Record</a>
      {% has_permission_cust CHECK_COMPLIANCE %}
        {% url 'check_compliance' foo.bar_record.pk as check_compliance_url %}
        <a href="{{ check_compliance_url }}" class="button">Check Compliance</a>
      {% end_has_permission_cust %}
    </td>
  </tr>
  {% endifchanged %}
  {% endif %}
{% empty %}
{% endfor %}

检查模板标签中是否is_off但ischange是否检测到更改
