在 RoR 中重新打开课程的位置 [英] Where to reopen a class in RoR

问题描述

我正在尝试重新打开 rails 中的 String 类并添加更多方法供我的应用程序使用.编写代码不是问题 - 我的问题是这段代码应该放在什么地方.

I'm attempting to reopen the String class in rails and add a bunch more methods for my app to use. Writing the code isn't a problem - my question is rather about where this code should go.

在不同的模型文件中重新打开一个类对我来说没有意义，因为它实际上与任何模型都没有任何关系.我想也许在 config 或 lib 的某个地方会有意义，但我还不是特别精通 RoR.

It doesn't make sense to me to reopen a class inside a different model file, because it really has nothing to do with any of the models specifically. I thought perhaps somewhere in config or lib would make sense, but I'm not particularly well versed with RoR yet.

总而言之，定义类修改代码最合乎逻辑的位置是什么，根据代码加载的位置/时间，是否有任何影响?

To summarize, where would be the most logical place to define class-modifying code, and are there any implications depending on where/when the code is loaded?

推荐答案

最合乎逻辑的地方可能是 config/initializers 目录中的一个文件.任何你放入这里的 *.rb 文件都会在 rails 启动时自动执行.如果你愿意，你可以把它们放在一个子文件夹中，这样你就可以做类似 config/initializers/extensions/*.rb 的事情.

The most logical place is probably in a file in the config/initializers directory. Any *.rb file you put in here will be automatically executed when rails boots. If you want, you could put them in a sub folder, so you could do something like config/initializers/extensions/*.rb.
