I am working with rails 3 & using act_as_tree. How can I iterate on nested json so that I can find difference between two nodes?
json that I want to compare looks like this :
{ "text": "To Do", "children": [{ "text": "Go jogging", "children":[] }, { "text": "Take a nap", "children":[] }] } and
{ "text": "To Do", "children": [{ "text": "Climb Everest", "children":[] }] } Please, take a look https://rubygems.org/gems/json-compare
It is possible do something to get the diff:
require 'yajl' require 'json-compare' json1 = File.new('spec/fixtures/twitter-search.json', 'r') json2 = File.new('spec/fixtures/twitter-search2.json', 'r') old, new = Yajl::Parser.parse(json1), Yajl::Parser.parse(json2) result = JsonCompare.get_diff(old, new) showing the diffs - i guess you need to deserialize the JSONs into structures, and compare the objects. That seems to me the easiest way.
As OhadR mentioned, de-serializing and comparing the objects seems to be a viable way.
For that, check this gem:

It even has an online demo of comparing JSON and YAML structures, and showing the differences.
