Defining external_asset_provider for Stylesheets

[regularlady]

@Mange thank you so much for making such a great gem.

A quick question for you: how would you define Amazon s3 as the external_asset_provider for hosted email stylesheets? I hunted around both roadie-rails and roadie and did not find the correct syntax for s3. We tried setting the external_asset_provider in the mail block below but did not have any luck.

Our email is built like this:

  class UserMailer < ActionMailer::Base
    include Roadie::Rails::Automatic
    layout "email"

    def self.branded_email_css
      "//awsbucket.s3.amazonaws.com/production/assets/branding/email"
    end

    def registration_confirmation_mail(user)
      @user = user

      mail({
               to: @user.email,
               from: "donotreply@hello.org",
               subject: "Welcome!",
               date: Time.now,
               content_type: "text/html",
               css: UserMailer.branded_email_css
           })
    end

  end

Thanks for your advice!

Hi,

Thank you for your kind words!

The style of passing css as an option to mail is no longer used in Roadie 3, and Roadie 2 could only access from the local file system.

Which version are you on?

Hi @Mange,

I'm using roadie-rails version 1.0.6 which depends on roadie 3.1.1. Does this mean we need to define our styles in-line? Thanks again for your response!

Yes, that's correct. If you look at the documentation for Roadie, you'll see how it works. Roadie-rails should allow you to use Rails' normal asset helpers.

If you need to download the assets, you can use an external_provider as documented in Roadie, although you set it on roadie_options in your Rails app.

Let me know if you need any code examples.
