如何在Rails项目中引用文件？

Question

I'm using Rails 5.0.1. I have a Java class file in my project located at

bin/java/WordToTextConverter.class

How do I reference this class from within a Rails file? For instance, in one of my service classes I have this

`java -classpath "#{Rails.configuration.java_class_path}" WordToTextConverter ${file_location} #{file_as_text}`

but this is currently failing because I haven't put in the correct path to "WordToTextConverter". What should that path be?

Answer 1

You can use Rails.root which would give you the full path of your current Rails application like:

/some_directory/rails_project/

So this way you can access the bin/ folder or any other you need to work with, so in your case you could try with:

"#{Rails.root}/bin/java"
