我有django应用程序（django 1.6），我有问题发送少量图像，上传少量图像。在前端这是可以的，我可以拖放图像并在那里看到它们。
按下保存按钮时问题开始了。从前端上传的少量图片，现在我只能看到一个。因此，例如，从前端的2个上传图像，现在我只能看到一个。
以下是我上传图片的HTML：
For ready batches within then only after that promise resolves, but for other batches there is no promise. So they can get executed quickly.这是我的<ul class="uploads">
{% for formset in forms%}
{{ formset.management_form }}
{% for a in formset %}
{% if 'can_edit_posts' in perm_list or a.attachment.value %}
<li class="{% if not a.attachment.value %}empty{% endif %}" data-form-name="{{ a.attachment.html_name }}">
{{ a.id }}{{ a.post_locale }}
{{ a.attachment.value.url }}
{{ a.attachment.html_name }}
<div class="preview">
<div class="action">
<span class="icon-hospital">Add Image</span>
</div>
<img src="{% thumbnail a.attachment.value 400x400 autocrop=False %}" alt="">
<input class="upload-media" name="{{ a.attachment.html_name }}" type="file" value="{{ a.attachment.name }}" multiple>
<input type="hidden" class="files-to-exclude">
</div>
<div class="description">
<div class="filename">{{ a.attachment.value.name }}</div>
<div class="filesize">{{ a.attachment.value.size }}</div>
<ul class="btn-group">
<li class="download">
<a class="button icon-download-alt" href="{{ a.attachment.value.url }}" target="_blank"></a>
</li>
{% if formset.can_delete and 'can_edit_posts' in perm_list %}
<li class="delete">
{{ a.DELETE }}
<label for="{{a.DELETE.auto_id}}" class="button icon-trash"></label>
</li>
{% endif %}
</ul>
</div>
<div class="previews"></div>
</li>
{% endif %}
{% endfor %}
{% endfor %}
