使用向导生成Odoo11自定义报告。格式错误:不是PDF或损坏

Question

我试图打印一个基于向导的Odoo自定义报告。它从向导视图中获取输入。该向导允许用户使用start_date和end_date选择一个项目。然后单击“打印”按钮。因此，与向导表单字段筛选器匹配的活动列表应该在PDF中打印。但是我得到了一个带有PDF的0 KB文件，当我尝试打开时，我得到了Format error: Not a PDF or corrupted.，控制台中没有错误，这里有一些关键文件

reports/__init__.py

# -*- coding: utf-8 -*-


from odoo import models, api
class ReportWorkPlan(models.AbstractModel):
    _name = 'ewonga_pta.report_model_work_plan'

    @api.model
    def render_html(self, docids, data=None):
        docs = self.env['ew.pta.line'].browse(docids)


        docargs = {
            "doc_ids": docs.ids,
            "doc_model": "ew.pta.line",
            "docs": docs,

        }
        return docargs

Answer 1

尝试删除通过"report_action“调用传递的”数据“参数。Self已经包含数据。

谢谢
