Rails4: image_url not generating digest in controller

I have this code:

class ExampleController < ApplicationController
  include ActionView::Helpers::AssetUrlHelper

  def show
    respond_to do |format|
      msg = { status: "ok", message: "Success!", image_url: image_url('image.png') }
      format.json  { render :json => msg }
    end
  end
end

This return me this response:

{ status: "ok", message: "Success!", image_url: 'images/image.png' }

And I expect something like:

{ status: "ok", message: "Success!", image_url: 'assets/image-37bf76be1.png' }

What is the problem?

Solution

  • I believe you need to use view_context.image_url if you want to render an image from the controller.
