print json fields and data on ruby

Question

I'm working on ruby and i have the following line:

error = new_user.errors.to_json

if I do puts error the following json would be printed: {"email":["is invalid"]} and I want is to show the following text "the email entered is invalid" so how can I access both key and value from json?

thanks

It seems to be ActiveRecord Validation errors attribute. At model level validation, you can use 'message' option and set your custom error message. validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/i, :message => "The email entered is invalid" — Alok Anand

if you want to print the error messages, my suggestion is to try like this,

new_user.errors.full_messages.each do |error| 
  puts error 
end

to know more about ActiveRecord errors take a look the links ActiveRecord::Errors, Working with Validation Errors
