ruby-on-rails - 使用 ruby 保存/更新(轻便摩托车)BSON::Document
我尝试了很多方法来更新现有的 bson 文档,但它在我的 mongodb 中从未改变:
第一次尝试更新:
第二次尝试更新:
第三次尝试……
如您所见,以上都不适合我。我无法通过谷歌搜索找到任何其他建议。你知道如何更新我的文件吗?是否可以?
ruby-on-rails - 不使用模型的 Mongoid 迁移更新字段从字符串到时间戳
我想更新一个集合的字段,它实际上有一个日期的字符串表示,并将其更改为 ISODate。
我已经有了解决方案,但是效率低下:
我想在一次操作中更新它,而不是搜索和更新每条记录。
ruby-on-rails - 使用一个操作存储一组 mongoid 文档
使用Moped
gem 时,我可以存储一个哈希数组:
对于 mongoid 文档,它看起来像:
这意味着每个的插入操作。你知道保持单一操作方法的方法吗?也许像交易一样ActiveRecord
?
ruby - 如何在 ruby mongoid 应用程序中测量轻便摩托车插入运行时间?
我目前正在编写一个轻便摩托车日志解析器,以监控轻便摩托车查询运行时。使用运行时参数的 QUERY 命令非常有用,但 INSERT 和 UPDATE 没有运行时参数。所有 INSERT 和 UPDATE 后跟一个包含运行时的getLastError命令。
以下是一些轻便摩托车日志的示例:
使用运行时查询
INSERT 没有运行时但使用 COMMAND
我很确定 COMMAND 运行时用于 getlasterror 调用,而不是用于我的 INSERT 调用。那么有没有办法为 INSERT 查询获取此运行时信息?
ruby-on-rails-3 - Resque 工作人员中的间歇性“Moped::Protocol::Command failed with error nil”错误
我正在使用 Rails 3.2、Mongoid 3.1.7、Moped 1.5.3 和 Resque 1.24.1
我的 Resque 工作人员反复收到“Moped::Protocol::Command failed with error nil”[1] 错误。
这个问题,以及Moped 回购中的这个问题让我认为这可能是由于 Resque 分叉,但它们都是关于旧版本的 Moped,而不是我正在使用的,而且我一直无法找到任何具体信息将 Resque 配置为与 Mongoid 很好地协同工作。
如何解决我的 Resque 工作人员中的错误?
[1] 完全错误:

ruby-on-rails - 如何强制轻便摩托车从延迟运行的 Mongo 辅助副本集成员读取
我有一个基于 ruby on rails 的应用程序。目标是从一个 mongo 副本集成员中读取:
secondary
delayed by x seconds
priority: 0
- 放置在单独的数据中心。
DETAILS
:我有一个使用 mongo 副本集的生产集群正在运行。
以前,有人注意到,有时 Moped 从其他具有高延迟的辅助节点(远程存在于其他数据中心)而不是从所需的辅助节点读取。为了解决同样的问题,我们在远程辅助节点上添加了延迟。
现在我有一个使用 mongoid 的新分析应用程序。有没有一种方法可以强制使用 mongoid 或任何其他 gem 从 SPECIFIC 二级读取?即有没有办法覆盖 Mongoid / Moped / MongoDB 中的自动发现功能?请建议
ruby-on-rails - 助力车“无效的集合名称”
我最近在我的 rails 应用程序中将 mongoid 从 2.0 升级到了 3.0.0 版本。在执行保存对象(现有对象或新对象)的操作时,我Moped::Errors::OperationFailure: The operation: #<Moped::Protocol::Command
会说存在invalid collection name"
.
对象的 full_collection_name 返回foo_development.$cmd
,Mongoid.default_session.collections
返回空数组,但是当我通过 mongo 客户端访问数据库时,所有集合都已到位。
我的 mongoid.yml
development:
sessions:
default:
database: foo_development
hosts:
- localhost:27017
mongodb - 如何在 mongoid/moped/mongodb 中启用异常
当我order_by
的属性未知时,我的设置会静默失败。有没有办法改变这种行为,快速失败并出现错误/异常?
它使调试代码变得极其困难。
ruby-on-rails - Mongoid中的Mongo查询超时
如何在 Mongoid 中为我的 Mongo 查询设置超时?我知道 Mongo 支持cursor.maxTimeMS()
但在 Mongoid 文档中找不到它。
