Rails: How do I print the request parameters?

Question

I have a Rails 3 application and I want to print in the view the request parameters. How do I do it?

Edit:

The purpose is to see what is being sent in a Form

Answer 1

Something like

<%= params.inspect %>

works, but what I would like to add is the following gem and Chrome plugin which was literally an eye-opener.

I am putting it here because I think it will help people check out params hashes, see SQL queries or view Errors.
