Rails 4:在子路径中组织Rails模型而不使用命名空间模型吗? [英] Rails 4: organize rails models in sub path without namespacing models?
问题描述
有可能有这样的东西吗?
Would it be possible to have something like this?
app/models/
app/models/users/user.rb
app/models/users/education.rb
目标是更好地组织/app/models 文件夹，但不必为模型命名空间.
The goal is to organize the /app/models folder better, but without having to namespace the models.
Rails 3的一个未解决的问题在这里: 导轨3.2.9和子文件夹中的模型.
An unanswered question for Rails 3 is here: Rails 3.2.9 and models in subfolders.
使用名称空间指定table_name似乎可以正常工作(请参阅 Rails 4 model子文件夹)，但是我要在没有命名空间的情况下执行此操作.
Specifying table_name with namespaces seems to work (see Rails 4 model subfolder), but I want to do this without a namespace.
推荐答案
默认情况下，Rails不会将models目录的子文件夹添加到自动加载路径中.这就是为什么它只能找到命名空间模型的原因-命名空间照亮了要查找的子目录.
By default, Rails doesn't add subfolders of the models directory to the autoload path. Which is why it can only find namespaced models -- the namespace illuminates the subdirectory to look in.
要将 app/models 的所有子文件夹添加到自动加载路径，请将以下内容添加到 config/application.rb :
To add all subfolders of app/models to the autoload path, add the following to config/application.rb:
config.autoload_paths += Dir[Rails.root.join("app", "models", "{*/}")]
或者，如果您有一个更复杂的 app/models 目录，则将 app/models 的所有子文件夹组合在一起的上述方法可能无法正常工作.在这种情况下，您可以通过更加明确的方式并仅添加指定的子文件夹来解决此问题:
Or, if you have a more complex app/models directory, the above method of globing together all subfolders of app/models may not work properly. In which case, you can get around this by being a little more explicit and only adding the subfolders that you specify:
config.autoload_paths += Rails.root.join("app", "models", "<my_subfolder_name1>")
config.autoload_paths += Rails.root.join("app", "models", "<my_subfolder_name2>")
Rails 4.1+的更新
从Rails 4.1开始，默认情况下，应用程序生成器不包含config.autoload_paths.因此，请注意，以上内容确实属于 config/application.rb .
UPDATE for Rails 4.1+
As of Rails 4.1, the app generator doesn't include config.autoload_paths by default. So, note that the above really does belong in config/application.rb.
修复了上面代码中的自动加载路径示例，以使用{*/}代替{**}.请务必阅读 muichkine的评论以获得详细信息.
Fixed autoload path examples in the above code to use {*/} instead of {**}. Be sure to read muichkine's comment for details on this.
