新增product.template字段后，升级purchase模块出错

floatingdudu

请教大神：
我继承product.template新增了prd_version字段，可以正常使用。但是当我升级purchase模块时，却提示找不到prd_version字段，错误信息如下。请问是什么原因？

错误信息:

你的模块的__manifest__.py 文件中的depends应该有问题。能贴出来看一下吗？
另外，你贴代码的时候，可以把代码包在三个反点中，比如``` mycode ``` ，这样就会保持格式，并且有语法高亮。

在purchase模块的__manifest__.py depend中增加新增的模块后，问题解决了。

@floatingdudu 在新增product.template字段后，升级purchase模块出错中说：

在purchase模块的__manifest__.py depend中增加新增的模块后，问题解决了。

感谢大神指导

问题应该没有解决:beaming_face_with_smiling_eyes: 。你新创建了一个模块，然后还要在原生模块里添加对你的新模块的依赖？完全不懂这个逻辑。
