Question

我目前正在开发一款SailsJS应用。我开始使用版本0.10.5并实现了许多具有它们之间继承的模型。一切都很好。

今天，我决定将我的SailsJS项目更新为0.11.0版。我读过最简单的方法是用npm更新所有SailsJS文件，然后创建一个新项目，最后将所有模型，控制器等复制到新创建的项目中。这是我到目前为止所做的。

我每次尝试解除项目时都会遇到问题：

/usr/local/lib/node_modules/sails/node_modules/waterline/node_modules/waterline-schema/lib/waterline-schema/foreignKeys.js:82
    throw new Error('Trying to access a collection ' + collection + ' that is 
          ^

有我的模特：

你能解释一下我做错了什么吗？我无法理解为什么它不再起作用了（提醒：它在0.10.5版本中运行良好）。

感谢阅读，祝你有愉快的一天：）

Answer 1

您的所有模特都应该在api/models。无处。如果你只是遵循惯例，一切都会奏效。

如果你有扩展的“基础”模型，如果你不想在数据库中为它们创建表格，只需将它们放在api/之外。

Answer 2

好的伙计们。我找到了解决方案：我必须将所有基本模型从 / api / services 移到 / api / base 。现在它有效，但我不知道为什么。也许自上次更新以来，SailsJS不再在/ api / services中发挥其魔力。

自v0.11.0起，SailsJS One-To-Many无法正常工作
