我正在使用 meteor，我正在尝试从 meteor 1.6 升级到 1.7 但是我遇到了无法在我的测试中获取有关信息的错误:

我得到了很多这样的东西(有些可能是重复的、未使用的或过时的):

Error: Updating the path 'relationChangeRate' would create a conflict at 'relationChangeRate'

1.6.* 中没有出现

我尝试将我的 mongodb 升级到 3.6.6，但没有效果。 我也无法在测试中获取整个堆栈以查看究竟执行了什么。

如果您对发生的事情有任何线索？ 我可以提供有关应用程序中发生的情况的更多信息，但现在简单解释此错误的含义就已经很棒了。正如我所说，此错误仅附加在 1.7 中。

编辑:忘了说我的测试在工作代码上抛出这个。 功能运行良好，但测试运行不佳。

编辑²:

此方法是更新集合项目设置的方法。

_duplicateProjectSettings(newSession) {
  const settings = this.session.projectSettings();
  delete settings._id;
  settings.sessionId = newSession._id;
  const newSettings = newSession.projectSettings();
  ProjectSettings.update(newSettings._id, { $set: settings });
}

relationChangeRate 是 projectSettings 集合的一个简单模式字段(我使用 collection2-core):

relationChangeRate: {
  type: Number,
  allowedValues: _.values(RelationRates),
  defaultValue: 0.0
}

projectSettings 扩展了 mongo.collection，但在这种情况下，更新方法没有被覆盖。 代码接缝对我来说是正确的，因为 _id 在更新请求之前被很好地删除并设置为新对象。但也许我错了？

编辑³:

ProjectSettings 是一个 collection-helper :

代码如下:

Sessions.helpers({
[...]
  projectSettings() {
      const conds = { sessionId: this._id };
      return ProjectSettings.findOne(conds);
  },
[...]

集合助手基本上是在该集合中的每个文档上添加一个方法。这意味着任何 session 对象都会有这个方法。在集合助手中，“this”指的是当前集合对象。

这样应该不错吧？

_duplicateProjectSettings 可以这样写:

_duplicateProjectSettings(newSession) {
  // const settings = this.session.projectSettings();
  const settings = ProjectSettings.findOne({ sessionId: this.session._id });
  delete settings._id;
  settings.sessionId = newSession._id;
  // const newSettings = newSession.projectSettings();
  const newSettings = ProjectSettings.findOne({ sessionId: newSession._id });
  ProjectSettings.update(newSettings._id, { $set: settings });
}

(我也试过了，结果一样)

最佳答案

从 shell 运行它对我有用……不是最好的解决方案。我在尝试使用 accounts-password 包登录时遇到了问题。

$ meteor mongo
meteor:PRIMARY> db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )

关于mongodb - 迁移到 meteor 1.7.0.4 : MongoDB : "updating the path ... would create a conflict at ..."，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51827085/
