指定“app”路径的正确方法是什么?在 Rails 插件中?
出现这个问题是因为 cells gem 使用 File.join('app','cells') 指定模板目录。除非您将 Rails 作为守护进程运行(scripts/server -d),否则效果很好。守护进程将目录切换到 / ,这使得单元模板路径指向错误的绝对路径。
我的解决方案是将默认路径设置为 File.join(RAILS_ROOT, 'app', 'cells')。这在 Rails 中有效,但插件的单元测试失败,因为未定义 RAILS_ROOT。使用 File.join(File.dirname(__FILE__),'..'
... 也可以,但需要大约 6 个级别的 '..' 这似乎是错误的。
所以我的问题是什么是正确的在 Rails 插件中指定“app”下目录的路径的方法?还是有其他错误导致守护进程 Rails 无法找到相对路径?
This question came about because the cells gem specifies template directories using File.join('app','cells'). That works fine until you run Rails as a daemon (scripts/server -d). The daemon switches directories to / which leaves the cells template paths pointing to the wrong absolute path.
My solution was to set the default paths to File.join(RAILS_ROOT, 'app', 'cells'). This works in Rails, but the unit tests for the plugin fail because RAILS_ROOT isn't defined. Using File.join(File.dirname(__FILE__),'..'
... also works but requires about 6 levels of '..' which seems wrong.
So my question is what is the proper way to specify the path to a directory under 'app' in a Rails plugin? Or is there something else wrong that would cause daemonizing Rails to fail to find the relative paths?

我建议将您的更改从插件中移出并放入初始值设定项中。在初始化程序中重写使用 File.join('app','cells') 的方法。这有几个好处。
I suggest moving your changes out of the plugin and into an initializer. In the initializer override the method that uses File.join('app','cells'). This has several benefits.
对于那些难以破译这个答案的人,这对我有用:
创建一个文件 config/initializers/cells.rb
在其中
:希望这会有所帮助
For those who had trouble deciphering this answer, here is what worked for me:
Create a file config/initializers/cells.rb
in it put:
Hope this helps
