Hi folks.  I want to display the parameters in a nice way, iterated through each param and display the key and its value.  How can I get this done?

This is what I have:

    -a = params.count
   
- 0..a do |i|
       
%p= "#{params.keys[i]} = #{params.values[i]}"

All I get is an ISE.  Still getting used to the syntax here.  

Any advice appreciated.  Cheers

Try `params.each do |key, value|`.

Actually got it to work:

-a = params.count
- (0..a).each do |i|
%p #{params.keys[i]} = #{params.values[i]}
