I have the exact same problem, the code shown in README actually produces wrong JSON.

arr = [1,2,3,4,5,6,7,8,9,0]
json = JSONBuilder::Generator.new
json.posts do
  json.array! arr do
    arr.each do |a|
      json.array_item! do
        json.id a
      end
    end
  end
end
puts json.compile!

The above code produces:

[{"posts":{"id":1},{"id": 2},{"id": 3},{"id": 4},{"id": 5},{"id": 6},{"id": 7},{"id": 8},{"id": 9},{"id": 0}}]

But it should produce:

{"posts":[{"id":1},{"id": 2},{"id": 3},{"id": 4},{"id": 5},{"id": 6},{"id": 7},{"id": 8},{"id": 9},{"id": 0}]}

I have fixed this with json_builder 3.0 which I am releasing shortly, which has a new and easier to use API. So to do that with the new API, it will be:

posts [1,2,3,4,5,6,7,8,9,0] do |i|
  id i
end
