convert JSON array to Ruby Hash (of hashes)

Tag: ruby,json

I'm trying to convert some API response data into a Ruby hash or array so I can more easily work with it. Here's the JSON string being returned by the API:

[
  {
    "id": 2,
    "name": "TestThing",
    "token": "B2CA27221DB976E48248F26756289B91"
  },
  {
    "id": 3,
    "name": "AnotherTestThing",
    "token": "EF16E5F20B8463E48DBF3BA8F0E1102A"
  }
]

I believe that is a JSON array? I tried doing JSON.parse on that string, but got (JSON::ParserError)r/.rvm/rubies/ruby-1.9.3-p551/lib/ruby/1.9.1/json/common.rb:148:in 'parse': 746: unexpected token at '1511

What is the best way to convert this into something I can easily work with? My real goal here is to iterate over the tokens returned.

Best How To :

My question did not show the full string I was trying to JSON.parse. I only put what I was trying to parse. I accidentally left some floating data before the JSON part of my string. Now that I have deleted that, it is working.

why i don't get return value javascript

javascript,jquery,html,json,html5

the first "A" in AJAX stands for "Asynchronous" that means, it is not executed right after it has been called. So you never get the value.

Make instance variable accessible through hash in Ruby

ruby-on-rails,ruby,ruby-on-rails-4,activerecord

It's not "through Hash", it's "array access" operator. To implement it, you need to define methods: def [](*keys) # Define here end def []=(*keys, value) # Define here end Of course, if you won't be using multiple keys to access an element, you're fine with using just key instead of...

DO include absolute entity URIs in your responses (such as /customers/12 or even http://www.example.com/customers/12). DO NOT include just an entity's ID (such as 12) in a response, because that way you're forcing clients to put together resource URIs themselves. In order to do that, they would need to have prior...

Short answer: no, you cant. 2.1.5 :001 > 0001 => 1 0001 doesn't make sense at all as Integer. In the Integer world, 0001 is exactly as 1. Moreover, the number of leading integer is generally irrelevant, unless you need to pad some integer for displaying, but in this case...

Rather than using the collection_select directly, you can use select and pass the result of a options_from_collection_for_select call. The reason you may want to call options_from_collection_for_select directly, is because this method also accepts an optional selected parameter that could be used to pass a...
