Custom filtering of parameters in rails 3 using config.filter_parameters

Question

I\'m working on upgrading from Rails 2.3.11 to 3.0.10, and am having trouble converting what is in the ApplicationController\'s filter_parameter_logging

Figured it out. You can pass a lambda statement to config.filter_parameters, so after I add the parameters to filter, I have this now:

config.filter_parameters << lambda do |k,v|
  begin
    # Bail immediately if we can
    next unless v =~ FILTER_WORDS_REGEX && (v.index("=") || v.index("%3D"))

    #Filters out values for params that match
    v.gsub!(FILTER_WORDS_GSUB_REGEX) do
      "#{$1}=[FILTERED]#{$2}"
    end
  rescue Exception => e
    logger.error e
  end
end
