Odoo14 Tree视图创建按钮后面增加按钮

1.继承ListView.buttons,在其按钮后面增加我们自定义的按钮,通过widget的一些属性去判断按钮的显示

<templates id="list_import_shipping_button_create" xml:space="preserve">
  <t t-extend="ListView.buttons">
      <t t-jquery="div.o_list_buttons" t-operation="append">
          <!-- 找到名为 ""的模型，并在它的列表(tree)视图后面append一个按钮 -->
          <t t-if="widget and widget.modelName == 'ffb.shipping.order' and widget._title == '国际运输单' and widget.controlPanelProps.action.context.is_show">
              <button class="btn btn-success o_list_tender_import_shipping" type="button">导入</button>
          </t>
      </t>
 </t>
</templates>

2.在js中增加对该按钮增加click事件,弹出向导

odoo.define('ffb_internation_shipping.list_import_shipping_button_create', function (require) {
    "use strict";
    var ListView = require('web.ListView');
    var viewRegistry = require('web.view_registry');
    var ListController = require('web.ListController');
    ListController.include({
        renderButtons: function ($node) {
            this._super.apply(this, arguments);
            if (this.$buttons) {
                this.$buttons.on('click', '.o_list_tender_import_shipping', this.inport_voyage_shipping.bind(this));
            }
        },
        inport_voyage_shipping: function () {
            var self = this;
            self.do_action({
                type: 'ir.actions.act_window',
                name: '国际运输单导入',
                target: 'new',
                res_model: 'import.shipping.wizard',
                views: [[false, 'form']],
            });
        }
    });
});
