Question

I am working on a web application running on Rails 2.1 version.

I would like to know if there is any single command in rails or ruby that could fetch me in the console, all the details about my application like the version of my back end DB, Rails, Ruby and all relevant information pertaining to my web app.

This would help me to get all necessary details of my application without having to explicitly
look into each of the details one by one.

Answer 1

I think you can try the ruby script/about command for your rails app. This must work for the Rails 2.1 version.

Running this in the console would give you major environment details about your web application. Something similar to this :

Go to the app directory and run the command

$ ruby script/about
