Rails 5 API - How to respond with HTML on a specific controllers as an exception?

I have Rails API app. And 99% of the routes are JSON routes. however, I want to add one single route that will response with HTML. How can I do that?

This is my current setup and when I browse the route I see a string of HTML tags on the screen.

class ApplicationController < ActionController::API
   include ActionController::MimeResponds      
end

class DocumentPublicController < ApplicationController
  respond_to :html

  def show
    html = "<html><head></head><body><h1>Holololo</h1></body></html>"#, :content_type => 'text/html'
    respond_to do |format|
      format.html {render html: html, :content_type => 'text/html'}
    end
  end
end

Any ideas?

Solution

  • According to the Layouts and Rendering Guide:

    When using html: option, HTML entities will be escaped if the string is not marked as HTML safe by using html_safe method.

    So you just need to tell it the string is safe to render as html:

    # modified this line, though could be done in the actual render call as well
html = "<html><head></head><body><h1>Holololo</h1></body></html>".html_safe

respond_to do |format|
  format.html {render html: html, :content_type => 'text/html'}
end
