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.

In Ruby how to put multiple lines in one guard clause?

ruby-on-rails,ruby

Don't know what the surrounding code looks like so let's assume your code is the entire body of a method. Then a guard clause might look like this: def some_method return if params[:"available_#{district.id}"] != 'true' @deliverycharge = @product.deliverycharges.create!(districtrate_id: district.id) delivery_custom_price(district) end ...

Can't save json data to variable (or cache) with angularjs $http.get

Link to another resource in a REST API: by its ID, or by its URL?

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...
