如何解决Rails模型命名空间冲突 [英] How to resolve Rails model namespace collision

问题描述

到目前为止的故事：

我有一个名为Term的模型的轨道应用程序。一切都很好，直到尝试安装黄瓜。运行

I have a rails app with a model named "Term". All is well until trying to install Cucumber. Upon running

rake cucumber

我获得

Term is not a class (TypeError)

这是因为Cucumber包含另一个gem，'term-ansicolor'（在控制台中执行漂亮的彩色文本输出）和term-ansicolor定义名为Term的模块。黄瓜在包括Rails模型之前包括term-ansicolor，因此，当加载term模型时，Term已经被定义为模块。顶级模块和类在Ruby中不能有相同的名称，因此会产生冲突。

This happens because Cucumber includes another gem, 'term-ansicolor' (to do the nifty colored text output in the console), and term-ansicolor defines a module named "Term". Cucumber includes term-ansicolor before including the Rails models, thus "Term" is already defined as a module when loading the "Term" model. Top-level modules and classes cannot have the same names in Ruby, thus the collision.

我不想重命名模型，我设置了修补term-ansicolor gem。这被证明比我想象的难。我将Term模块名称更改为ANSITerm，但我无法弄清楚如何获取Cucumber来加载我修改的gem，我已将其放入RAILS_ROOT / vendor / gems / term-ansicolor。

Preferring not to rename the model, I set about patching the term-ansicolor gem. This proved harder than I thought. I changed the Term module name to "ANSITerm", but I can't figure out how to get Cucumber to load my modified gem, which I've put into RAILS_ROOT/vendor/gems/term-ansicolor.

任何想法？

Any ideas? Am I barking up the wrong tree?

推荐答案

两种解决方案：

1）将应用的Term模型更改为其他类型。

1) Change your app's Term model to be something else.

2）补丁术语-ansicolor有一个命名空间Term，并使用该gem。

2) Patch term-ansicolor to have a namespaced Term and use that gem instead.
