Pretty Print JSON with JBuilder

Question

I am using JBuilder as a JSON DSL. I have it working properly but cannot figure out how to pretty print JSON.

I want to use JSON.pretty_generate but that requires a string or a hash, and JBuilder is a custom JBuilder object that does not convert.

Any ideas how to pretty print JSON with JBuilder template?

Try parsing the JBuilder output, then using JSON.pretty_generate on that resulting output

json_builder = Jbuilder.encode do |json|
  ... your json.data ...
end

json_obj = JSON.parse(json_builder)
puts       JSON.pretty_generate(json_obj)

I use pretty output for all my JSON in development by using an initializer for multi_json (the current backend for jbuilder):

In config/initializers/multi_json.rb

require 'multi_json'

MultiJson.dump_options = { pretty: true } if Rails.env.development?
