Answer 1

number_with_precision expects the second parameter to be the hash of the parameters

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

In general, whenever you see the undefined method "symbolize_keys!", It means that you are passing another object or value where Ruby / Rails expects a Hash .

Answer 2

putting this here for those who do not use Ruby, but sees this error when using an API that is encoded in Ruby, for example, Clock Hotel Software. I sent the JSON string as {"date":"2013-04-05","value":3} and received an error. it turned out that I had to place the array instead: [{"date":"2013-04-05","value":3}] fixed the error.
