How to view debug code in Thin console window?

问题:

In Mongrel, we are able to see any ruby debug code. After installing thin and doing thin start. I don't see any debug code on the console window.

Is this nromal?

Are we supposed to use tail -f log/development.log in a new console window to view the debug code?

回答1:

Yes. The solution with tail is normal, and you should use it.

回答2:

You could also try to start your server this way :

rails server thin

It shows your log, in Rails 3 at least.

回答3:

You can use a Procfile with foreman:

Procfile

web: thin start -p $PORT
logger: tail -f log/development.log

Example

$ foreman start -p 3000

The solution is to add a small code snippet in your config.ru file, and thin output all app logs to the console. You do not need to tail the log file, and it keeps log coloring intact
