Jets Custom Upcase Renderer
Here’s a cheatsheet for the simplest custom renderer ever that simply does an upcase.
Setup Template Handler
To add a custom render, you can register new template handlers. This is typcially done in the initializer.
config/initializers/renderers.rb
class UppercaseRenderer
def self.call(template, source = nil)
source ||= template.source
source.upcase.inspect
end
end
ActionView::Template.register_template_handler(:upcase, UppercaseRenderer)
Use in View
app/views/examples/index.html.upcase
This text will be rendered in upcase.
Controller
app/controllers/examples_controller.rb
class ExamplesController < ApplicationController
def index
end
end
Routes
config/routes.rb
Jets.application.routes.draw do
get "/examples", to: "examples#index"
end
