How to loop through attributes in rails controller params -


i have has_many relationship , want loop field on each of items link main model (ingredients on recipe). im trying in before_filter can parse users input correctly want. how can set loop params want

the request parameters in rails accessible via params hash. can loop on hash using iterator.

params.each |k,v|   puts "#{k}: #{v}" end

as parsing user's input, not in before_filter method. gave example below of converting input such "1 1/2" 1.5. try this:

ingredient.rb:

# amount :decimal (assuming column exists on ingredients table)  def humanized_amount   amount.humanize! end      def humanized_amount=(value)   amount = cast_humanized_value_to_decimal(value) end

then use humanized_amount attribute form input. suggestion. there's not right answer.
