Ruby create JSON from SQL Server-CodePudding

I am trying to create JSON in Ruby from data coming from a SQL Server table, based off a query. I've worked with Ruby quite a bit and JSON some. But never together.

This is a sample of the JSON I'm trying to create.

Even help with just creating the JSON with the nested arrays and the root element would be helpful.

{
  "aaSequences": [
    {
     "authorIds": [
        "ent_fdfdfdfdf_one"
      ],
      "aminoAcids": "aminoAcids_data",
      "name": "bbbbb-22",
      "schemaId": "ls_jgjgjg",
      "registryId": "src_fgfgfgf",
      "namingStrategy": "NEW_IDS"
    },
    {
     "authorIds": [
        "ent_fdfdfdfdf_two"
      ],
      "aminoAcids": "aminoAcids_data",
      "name": "bbbbb-22",
      "schemaId": "ls_jgjgjg",
      "registryId": "src_fgfgfgf",
      "namingStrategy": "NEW_IDS"
    }
  ]
}

CodePudding user response：

Generate a JSON from a Ruby hash object

To generate a json, first start with a hash (like a dict) in Ruby

my_hash = {:foo => 1, :bar => 2, :baz => 3}

Make sure you require the json package as well

require 'json'

Then you can simply convert the hash object to a JSON string

my_hash.to_json # outputs: "{'foo': 1, 'bar': 2, 'baz': 3'}"

You can nest arrays into your hash as well

my_hash_2 = {:foo => [1, 2, 3, 4], :bar => ['a', 'b', 'c', 'd']}

I'll let you try that one on your own, but ruby will handle the nested object just fine for you.
