I want to use Jbuilder with Rails 5.0.0.beta1.1 in API mode. Out of the box, it doesn't work, even when creating the app/views directory.
For example, I have:
# app/controllers/tests_controller.rb
class TestsController < ApplicationController
# The requests gets inside the action
def test
end
end
# app/views/tests/test.json.jbuilder
json.test "It works!"
The error I'm getting is
No template found for TestsController#test, rendering head :no_content
I guess I have to change some things in the config files. What do I have to do?

Jbuilder provides a DSL for generating JSON. It includes a template engine which allows you to create complex responses with helpers and conditions. If you look at the gemfile for a Rails 3.2 application you'll see a see a gem mentioned in the comments that wasn't there in earlier versions called JBuilder.
Jbuilder gives you a simple DSL for declaring JSON structures that beats manipulating giant hash structures. This is particularly helpful when the generation process is fraught with conditionals and loops. Here's a simple example: # app/views/messages/show.json.jbuilder json.
Jbuilder is a gem that's maintained by the Rails team and included in the default Rails Gemfile . It's similar to Builder but is used to generate JSON, instead of XML. If you don't have it, you can add the following to your Gemfile : gem 'jbuilder' Copy.
Jbuilder is quite useful when it comes to generating and rendering JSON responses for API requests in Rails. This article helps understand, how to render JSON responses in general. Jbuilder is particularly good at following things: Reusable JSON API responses through partials.
Doing an explicit render from the controller like this works:
render 'controller_name/action.json.jbuilder'
