method
filter_parameter_logging
filter_parameter_logging(*filter_words, &block)
public
Replace sensitive paramater data from the request log. Filters paramaters that have any of the arguments as a substring. Looks in all subhashes of the param hash for keys to filter. If a block is given, each key and value of the paramater hash and all subhashes is passed to it, the value or key can be replaced using String#replace or similar method.
Examples:
filter_parameter_logging => Does nothing, just slows the logging process down filter_parameter_logging :password => replaces the value to all keys matching /password/i with "[FILTERED]" filter_parameter_logging :foo, "bar" => replaces the value to all keys matching /foo|bar/i with "[FILTERED]" filter_parameter_logging { |k,v| v.reverse! if k =~ /secret/i } => reverses the value to all keys matching /secret/i filter_parameter_logging(:foo, "bar") { |k,v| v.reverse! if k =~ /secret/i } => reverses the value to all keys matching /secret/i, and replaces the value to all keys matching /foo|bar/i with "[FILTERED]"
