是不是用这个字段做条件的时候，没有提前先把这个字段给展示处理

首先检查下模块是否已经成功安装。
如果是用管理员登录应该刷新后就有显示。如果不是管理员请检查下权限是否设置正确。

你可以查看下服务器日志，应该会有相关提示。有可能是你的发件地址并没有和当前系统的任何单据有关，你可以试试将用户的邮件地址设置为你的发件地址。

@手可摘星辰 在 Odoo13新手求助 中说：

odoo.tools.convert.ParseError: "Invalid field 'view_type' on model 'ir.actions.act_window'" while parsing /ho me/odoo/odoo-dev/odoo/mymodules/openacademy/views/views.xml:1, near

检查下你的views.xml，view_type是旧版本才使用的，在Odoo V13可以去掉了。

这是因为你没有安装或配置财务本地化模块，比如‘China - Small Business CoA ’， 这个模块的作用是帮你创建本地化财务科目表，同时为业务对象设置默认的科目设定。

@digitalsatori 我使用odoo 13 community 版本，調整庫存數無法解決此問題

採用平均成本
自動計算庫存成本

當商品以外幣計價採購，可能因匯率變化，及四捨五入的問題，導致平均成本的改變
因而產生買入即賣出的成本不同，而造成庫存為0，仍有殘值

这个问题在Odoo 13这个版本里面还没有解决掉吗？

查看下服务启动的日志，你可以通过启动时添加--log-file='xxx.log' 配置日志文件的地址。

问题是在用docker镜像引发的，直接装系统包和源码安装没有这个问题。

安装过一个微信小程序 weshop website_sale 模块已经卸载了，

现在日志报错也改变了 成了以下这样

@小杜 在 odoo13版本，按钮隐藏功能函数赋值后没有隐藏效果？求解惑 中说：

@digitalsatori 在 odoo13版本，按钮隐藏功能函数赋值后没有隐藏效果？求解惑 中说：

invoice_count

是的，没有生成invoice,就是想通过方法write({'invoice_count':1}），隐藏掉开形式发票的按钮！write()后有测试print(invoice_count)值为1，就是按钮没有隐藏！不知为啥？

这是一个readonly的compute字段。可能你还不知道什么是compute字段，看这里：https://www.odoo.com/documentation/13.0/howtos/backend.html#computed-fields-and-default-values
