Question

So, I really don’t want any nulls passed into my server, because it destroys IE when rendered.

I think a before filter in teh ApplicationController would do the trick.

I kinda want to do something like params.gsub(/\000/,””) but since params is a hash, that won’t work.

What is the shortest way to do this?

Answer 1

Something like this should work:

def recursive_gsub(search, replace, value)
  case value
  when String
  value.gsub!(search, replace)
  when Array,Hash
  value.each{|v| recursive_gsub(search, replace, v)}
  end
end

Then recursive_gsub(/\000/,"",params) should work. You could even add this method to Hash if you want something prettier like params.recursive_gsub!(/\000/,"").
