JSONObject is a simple Ruby library for converting JSON objects into Ruby classes.
It:
-
Simplifies parsing JSON objects into classes
-
Creates a series of setters, getters with instance variables for your new classes
Installation could be simpler:
gem 'json_object', '~> 0.0.2'
or
gem install json_object
Once you have the gem installed crack open an IRB session:
require 'json_object'
json = '{ "first_name" : "David", "last_name" : "White" }'
obj = JSONObject.new json
=> #<Object:0x00000100859688 @first_name="David", @last_name="White">
obj.first_name
=> "David"
obj.last_name
=> "White"
obj.first_name = "Dave"
=> "Dave"You can also create new classes completely dynamically without ever writing a class in Ruby:
require 'json_object'
json = '{ "first_name" : "David", "last_name" : "White" }'
person = JSONObject.new json, "person"
=> #<Person:0x00000100859688 @first_name="David", @last_name="White">
person.first_name
=> "David"
person.last_name
=> "White"
person.first_name = "Dave"
=> "Dave"
person = Person.new
=> #<Person:0x00000100859688 @first_name="", @last_name="">
person.first_name = "Jeremy"
=> "Jeremy"
person.last_name = "White"
=> "White"And now you have a fully functioning Ruby class with data from your json file.
