ReferenceError:未定义实例

Question

这是我的XML代码。当我单击按钮时，它显示以下错误：

参考：未定义的实例

<?xml version="1.0" encoding="UTF-8"?>
<templates id="template" xml:space="preserve">
  <t t-extend="ListView.buttons">
    <t t-jquery="button.o_list_button_add" t-operation="after">
      <t t-if="widget.model=='ref.reference'">
        <button class="btn btn-sm btn-default" type="button">Enable</button>
        <button class="btn btn-sm btn-primary disable_ref" type="button">Disable</button>
      </t>
    </t>
  </t>
</templates>

这是在JavaScript中

var ListView = require('web.ListView');
ListView.include({
    render_buttons: function() {
        // GET BUTTON REFERENCE
        this._super.apply(this, arguments)
        if (this.$buttons) {
           var btn = this.$buttons.find('.disable_ref')
        }
        // PERFORM THE ACTION
        btn.on('click', this.proxy('do_new_button'))
    },
    do_new_button: function() {
        instance.web.Model('ref.reference')
            .call('ref_dis', [[]])
    }
})

将其更改为此

JS

odoo.define('reference.js', function(require) {
    'use strict';
var ListView = require('web.ListView')
var Model = require('web.Model')
    ListView.include({
        render_buttons: function() {
            this._super.apply(this, arguments)
            if (this.$buttons) {
                this.$buttons.find('.disable_ref').on('click', this.proxy('do_new_button'))
            }
        },
        do_new_button: function () {
            var model = new Model('ref.reference')
            model.call('ref_dis', [[]]);
        }
    })
})

型号

from odoo import fields, models, api
class ReferenceSource(models.Model):
    _name = "ref.reference"
    @api.model
    def ref_dis(self):
      some logic...
