通过(模型)表单字段访问图像(was:模型表单中的图像预览)

<p>
{% if field.errors %}
<span class="error">{{ field.errors }}</span>
{% endif %}

{{ field.label_tag }}:<br />

<img src="{{ field.value.url }}" /> {# <- This is what I want to do, I know it doesn't work like this #}

{{ field }}<br />
<span >{{ field.help_text }}</span>
</p>

谢谢你抽出时间。
