Pretty BSON::OrderedHash using Rails - ruby-on-rails

Question

If I pass a BSON::OrderedHash (from a MongoDb collection) to JSON.pretty_generate I get the json document but unformatted. How can I get a bson document formatted like .pretty() does?

Answer 1

It works for me with mongo 1.9.1, bson 1.9.1, and json 1.8.0 as shown in the following test code, as close as can be expected.
pretty_bson.rb
require 'mongo'
require 'bson'
require 'json'
require 'test/unit'
class BsonPrettyTest < Test::Unit::TestCase
def setup
#client = Mongo::MongoClient.new
#db = #client['test']
#coll = #db['people']
#coll.remove
assert_equal 0, #coll.count
end
test "bson pretty" do
text = <<-EOF
{
"firstName": "John",
"lastName": "Smith",
"age": 25,
"address": {
"streetAddress": "21 2nd Street",

"number": "212 555-1234"
},
{
"type": "fax",
"number": "646 555-4567"
}
]
}
EOF
hash = JSON.parse(text)
#coll.insert(hash)
doc = #coll.find_one
assert_equal BSON::OrderedHash, doc.class
puts JSON.pretty_generate(hash)
puts JSON.pretty_generate(doc)
end
end
