Rails Tip - How Do I See Params From My Forms?

I like to document what my forms are sending to my action methods. So most of the time, I create a method in my controller like this:

def to_export
  render :text => params.inspect
end

Then I use copy and paste to put the result into my code as a comment.

# {
#   "commit"=>"Upload File",
#   "authenticity_token"=>"17FvBH+Z4Meni6WvsCdPByrrk751BV9mNklzKDAo2Vc=",
#   "action"=>"do_import",
#   "import_criteria"=>{
#     "primary_language_name"=>"Creole",
#     "secondary_language_name"=>"English"
#   },
#   "form"=>{
#     "file"=>"traveling_haiti.txt"
#   },
#   "controller"=>"import"
# }
