无法在odoo 8中生成pdf报告

Question

当我尝试打印客户发票时出现错误：

Traceback (most recent call last):
  File "/home/ubuntu/liveAMS/openerp/addons/report/controllers/main.py", line 121, in report_download
    response = self.report_routes(reportname, docids=docids, converter='pdf')
  File "/home/ubuntu/liveAMS/openerp/http.py", line 403, in response_wrap
    response = f(*args, **kw)
  File "/home/ubuntu/liveAMS/openerp/addons/report/controllers/main.py", line 65, in report_routes
    pdf = report_obj.get_pdf(cr, uid, docids, reportname, data=options_data, context=context)
  File "/home/ubuntu/liveAMS/openerp/api.py", line 256, in wrapper
    return old_api(self, *args, **kwargs)
  File "/home/ubuntu/liveAMS/openerp/addons/report/models/report.py", line 198, in get_pdf
    save_in_attachment = self._check_attachment_use(cr, uid, ids, report)
  File "/home/ubuntu/liveAMS/openerp/api.py", line 256, in wrapper
    return old_api(self, *args, **kwargs)
 File "/home/ubuntu/liveAMS/openerp/addons/report/models/report.py", line 345, in _check_attachment_use
    pdf = base64.decodestring(pdf)
 File "/usr/lib/python2.7/base64.py", line 321, in decodestring
   return binascii.a2b_base64(s)
TypeError: must be string or buffer, not None

已安装 wkhtmltopdf：wkhtmltopdf 0.12.2.1（带有补丁的 qt）。

如何解决这个问题？

Answer 1

Odoo 可能正在尝试从数据库中加载一个空 PDF。在这种情况下，请尝试以下方法：

1. 启用调试/开发者模式 - 转到 yoursite.com/web?debug

2. 转到设置 > 技术 > 报告 > 报告

3. 搜索“发票”

4. 点击名称为Invoices和模板名称为account.report_invoice的报表记录

5. 点击编辑

6. 取消选中Reload from attachment

7. 点击保存

现在尝试再次打印发票。
