我正在尝试打印附件的条形码标签 . 我在文档页面的看板视图中添加了一个新按钮 . 我尝试打印所选文档的PDF报告 . 这是代码 .

*.js

odoo.define('documents.DocumentsInspector.inherit', function (require) 
{
"use strict";

var model = require('documents.DocumentsInspector');
var core = require('web.core');
var _t = core._t;
var qweb = core.qweb;
var BaseImport = require('base_import.import')
var rpc = require('web.rpc')

model.include({

 events: {
  'click .o_inspector_archive': '_onArchive',
  'click .o_inspector_delete': '_onDelete',
  'click .o_inspector_download': '_onDownload',
  'click .o_inspector_replace': '_onReplace',

  'click .o_inspector_print': '_onBarcodePrint',
},


/**

 */
_onBarcodePrint: function (ev) {

 var attachment_ids = [];
_.each(this.records,function(data){
  // console.log('data',data);
  attachment_ids.push(data.res_id)
}),

rpc.query({model: 'ir.attachment', method: 'print_barcode',args:[attachment_ids]})
 },
 });



});

report.AbstractModel

class PrintDocumentBarcode(models.AbstractModel):
_name = 'report.ean13_attachment.report_documentbarcode'
_description = 'Document Barcodes'

@api.model
def _get_report_values(self, docids, data=None):

    if data.get('atids'):
        doc = self.env['ir.attachment'].browse(data.get('atids'))
    else:
        doc = self.env['ir.attachment'].browse(docids)

    return {
        'doc_ids': docids,
        'doc_model': self.env['ir.attachment'],
        'docs': doc,

    }

ir.attachment

def print_barcode(self):
    data = {}
    data['atids']=self.ids
    return self.env.ref('ean13_attachment.action_report_documentbarcode').with_context(landscape=True).report_action(self, data=data)

函数 print_barcode 执行成功，但 _get_report_values 没有 .

我怎样才能做到这一点？
