Run ruby ​​script in rails application

This might be a dumb question, but I'm just wondering where, or if it can run a ruby ​​script that is not related to the rails application, I would like it to start. To clarify, I am working on a test automation package, which is written mainly in bash, but I want to create an interface (my rails application) that allows other users to run automated tests not from the command line. Therefore, I assume that basically I want the user to select certain parameters from the fields of the database or form, then transfer these parameters and pass them to the ruby ​​script, which causes my bash script automation. Hope this is clear. Thank!

If you want to call a script from a rails application, it becomes complicated. You want to use a background task or some order to complete these tasks, because they are blocking the server, and your users will wait for the call and download results to complete, which will most likely lead to a timeout.

See delayed_job and you can try creating a small ruby ​​script wrapper that can interact with your application.

Good luck
