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

If you wanted to print all of the parameters, the easiest way would be to use the inspect

puts params.inspect

or better, use the Rails logger

Rails.logger.debug params.inspect

In your html/ERB, you can use

<%= params.inspect %>

Answer 2

pretty_print also can be useful, in ruby and rails apps both

pp params
