I need to display all the posted variables and their values. I am not sure how I would go about doing this. Is there a way to loop through all the posted variables regardless of how many are passed so I could display them on a webpage? Thanks,

They're all in the params hash, which is just a regular ruby hash.

I understand that part, but what if I don't neccissarily know the names of the hash values? I know that there is always params[:action] and params[:controller], but what if I had params[:id] when I hit one method but when I hit another method I have a params[:admin_id], or something completely different. I guess when I am trying to ask (and the easy way would probably be just to try and see if it works) is, can I say params.each and then loop through all the values that are passed in regardless of what they are named before hand? Thanks,

Since it’s a Hash, you can do each to go through the keys and values
eg
params.each { |k, v| puts “the key #{k} has value #{v}” }
