How to replace a value in a multiple level nesting in YAML using ruby

Here is the YAML file:

test:
  title: ABC Company
  compId: '5161'
  accounts:
  - id: 1
    title: ABC Company
    MediaTypes:
    - title: AAA Company
      id: 66
      isSelected: true

I'm trying to write Ruby code to replace id: 1 (next level to accounts) to id: 2.

Here is my ruby code:

data = YAML::load(File.open(File.expand_path("../../../data/test.yml", __FILE__)))
data["test"]["accounts"]["id"] = 2
File.open((File.expand_path("../../../data/"test.yml", __FILE__)), 'w') {|f| f.write data.to_yaml }

When I run the script, the result is:

test:
  title: ABC Company
  compId: '5161'
  accounts: 2

Could someone please tell me what I did wrong? Thanks!

Try this instead:

data["test"]["accounts"][0]["id"] = 2

Remember that accounts is an array of hashes, not a hash.
