python - 附加操作按钮在 flask-admin 上不起作用

Question

我正在尝试向 flask-admin 表单添加一项操作。

它必须增加评级 (+1) 并且它适用于批处理操作，但不适用于单个操作。请帮我找到错误，我花了很多时间试图让这个东西正常工作。

代码如下:

我在模板文件夹中制作了一个 html 模板 - custom_lists.html

{% extends 'admin/model/list.html' %}
{% block list_row_actions %}
    {{ super() }}
  <form class="icon" method="POST" action="/admin/user/action/">
    <input id="action" name="action" value="approve" type="hidden">
    <input name="rowid" value="{{ get_pk_value(row) }}" type="hidden">
    <button onclick="return confirm('Are you sure you want to approve selected items?');" title="Approve">
      <span class="fa fa-ok glyphicon glyphicon-ok"></span>
    </button>
  </form>
{% endblock %}

这成功了，列表中有一个图标，但如果我点击它 - 它说

Not Found

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

添加到模板文件夹并添加到 AdidasView 类:

list_template = 'custom_list.html'
@action('approve', 'Approve', 'Are you sure you want to approve selected items?')
def action_approve(self, ids):
    try:
        query = Adidas.query.filter(Adidas.id.in_(ids))

        count = 0
        for image in query.all():
            image.rating += 1
            count += 1
            db.session.commit()
        flash(ngettext('Item was successfully approved.',
                       '%s items were successfully approved.'%count,count))
    except Exception as ex:
        if not self.handle_view_exception(ex):
            raise

        flash(gettext('Failed to approve items. %(error)s', error=str(ex)), 'error')

我没有更改模板，但我通过设置 column_extra_row_actions 变量和定义 action_play 函数做了不同的操作

column_extra_row_actions = [
        EndpointLinkRowAction('glyphicon glyphicon-play', 'event.action_play')
    ]

@expose('/action/play', methods=('GET',))
def action_play(self, *args, **kwargs):
    return self.handle_action()
