Ruby JSON.pretty_generate ... is pretty unpretty
- by Amy
I can't seem to get JSON.pretty_generate() to actually generate pretty output in Rails.
I'm using Rails 2.3.5 and it seems to automatically load the JSON gem. Awesome. While using script/console this does indeed produce JSON:
some_data = {'foo' => 1, 'bar' => 20, 'cow' => [1, 2, 3, 4], 'moo' => {'dog' => 'woof', 'cat' => 'meow'}}
some_data.to_json
=> "{\"cow\":[1,2,3,4],\"moo\":{\"cat\":\"meow\",\"dog\":\"woof\"},\"foo\":1,\"bar\":20}"
But this doesn't produce pretty output:
JSON.pretty_generate(some_data)
=> "{\"cow\":[1,2,3,4],\"moo\":{\"cat\":\"meow\",\"dog\":\"woof\"},\"foo\":1,\"bar\":20}"
The only way I've found to generate it is to use irb and to load the Pure version:
require 'rubygems'
require 'json/pure'
some_data = {'foo' => 1, 'bar' => 20, 'cow' => [1, 2, 3, 4], 'moo' => {'dog' => 'woof', 'cat' => 'meow'}}
JSON.pretty_generate(some_data)
=> "{\n \"cow\": [\n 1,\n 2,\n 3,\n 4\n ],\n \"moo\": {\n \"cat\": \"meow\",\n \"dog\": \"woof\"\n },\n \"foo\": 1,\n \"bar\": 20\n}"
BUT, what I really want is Rails to produce this. Does anyone have any tips why I can't get the generator in Rails to work correctly?
Thanks!
Updated 5:20 PM PST: Corrected the output.
