[SOLVED] Pretty Print JSON generated with a jbuilder template in Rails 3.2.8

Pretty Print JSON generated with a jbuilder template in Rails 3.2.8

Anyone have a way to pretty print JSON output from jbuilder?

I can pretty print JSON generated within a controller action with something like:

JSON.pretty_generate(some_json_object)

but once I pass off to a jbuilder template, I'm not aware of a way to have that output pretty printed.

Right now, my action method's render statement is simple:

render formats: :json

And this successfully forces a rendering with jbuilder, regardless of input format type specified (which is my desired behavior).

Solution

I think this is simpler,

@package = Package.first

json = JSON.parse(@blog.to_json)

PP.pp(json)

{"id_to_s"=>"5222675dbc11149e3a000002",
 "title"=>"Package Title",
 "version"=>"0.1.1",
 "comment"=>
  {"user"=>"Joe",
   "description"=>"Joe's comment"},
 "assets"=>
  [{"id_to_s"=>"522a4620fa451436f4000001",
    "_type"=>"Illustration",
    "start"=>0,
    "stop"=>100,
    "caption"=>"mountain climbing"},
   {"id_to_s"=>"522a56a6fa4514523a000001",
    "_type"=>"Illustration",
    "start"=>200,
    "stop"=>300,
    "caption"=>"airport"},
   {"id_to_s"=>"522a6a0ffa4514a30e000002",
    "_type"=>"Illustration",
    "start"=>400,
    "stop"=>600,
    "caption"=>"doc"},
   {"id_to_s"=>"522aa46bbc1114551f000001",
    "_type"=>"Illustration",
    "start"=>nil,
    "stop"=>nil,
    "caption"=>nil},
   {"id_to_s"=>"522aa47fbc1114551f000002",
    "_type"=>"Illustration",
    "start"=>10,
    "stop"=>30,
    "caption"=>"asdflkjsd"}]}

Or, the quicker one-liner,

PP.pp JSON.parse Blog.first.to_json
