What's the suggested way of providing parameters for bulk actions?

Let’s say I have an integer column and would like to use @action to change all the values to a new one, i.e. I need a intermediate page to be able the type in the new value. Any hints on how this can be done easiest?

I do it this way, using js.

{% extends 'admin/model/list.html' %}
{% block list_row_actions %}
    {{ super() }}
{% endblock %}

{% block model_menu_bar_before_filters %}
    <li id="here" class="form-row">
        <input name="pay_batch" class="form-control" placeholder="金额批量录入" aria-describedby="basic-addon1"/>
        <input name="memo_batch" class="form-control" placeholder="备注批量录入" aria-describedby="basic-addon1"/>
    </li>
{% endblock %}

{% block tail %}
    {{ super() }}
    <script type="application/javascript">
        $("input[name='memo_batch']").appendTo($("#action_form"))
        $("input[name='pay_batch']").appendTo($("#action_form"))
        $("#action_form").appendTo($("#here"))
        $("#action_form").attr("style", "")
    </script>
{% endblock %}

Then in coding file:

@action('batch_memo', '修改备注', )
    def action_batch_memo(self, ids):
        try:
            memo_batch = request.form['memo_batch']
            pay_batch = request.form['pay_batch']

            query = BankPay.query.filter(BankPay.id.in_(ids))

@daimon99 Thank you, this method saved me.

For others using the method here which requires a redirect 307 I hope they also find this comment. The method above does work and would be great for those who need to attach a large form to an action but it didn’t work in my production environment.

I’d like to append my version which places the inputs at the top of the block body. Which may be more versatile for others.

{% block body %}
  <div id="here">
    <div id="bank-reference" class="input-group" style="margin-bottom: 20px;">
      <span class="input-group-addon">
        <i class="glyphicon glyphicon-check"></i>
      </span>
      <input name="bank_ref" placeholder="Bank Reference" class="form-control">
    </div>
    <div id="bank-date" class="input-group" style="margin-bottom: 20px;">
      <span class="input-group-addon">
        <i class="glyphicon glyphicon-calendar"></i>
      </span>
      <input name="bank_date" class="form-control" type="date">
    </div>
  </div>
  {{ super() }}
{% endblock body %}

{% block tail %}
  {{ super() }}
  <script type="application/javascript">
    $("#bank-reference").appendTo($("#action_form"))
    $("#bank-date").appendTo($("#action_form"))
    $("#action_form").appendTo($("#here"))
    $("#action_form").attr("style", "")
  </script>
{% endblock tail %}
