I am using ruby 1.9.2 and rails 3. I am getting the following error while running my application.

Error:

           undefined method `symbolize_keys!' for 2:Fixnum  line #606 raised: 

Code: Line number 606

         <%= f.text_field :total_amount ,:label=>'Grand Total',:value =>number_with_precision(0,2),:readonly=>true %>

Please help me to correct this error. Thanks in Advance!!!

Answer 1

number_with_precision expects the second parameter to be an options hash

http://api.rubyonrails.org/classes/ActionView/Helpers/NumberHelper.html#method-i-number_with_precision

In general, whenever you see "undefined method 'symbolize_keys!'" it means you're passing in some other object or value where Ruby/Rails expects a Hash.
