ruby on rails 3 - image_tag in mailer not using asset_host

Question

image_tag isn't using the asset_host I've set. Any ideas why? The only thing I can think of is it having to do with it being a Mailer.

config/environment/development.rb

config.action_controller.asset_host = "http://localhost:3000"

myMailer.rb

<%= image_tag "logo.png", :style=>"margin-left:10px; padding-bottom:15px;" %>

rendered as:

<img alt="Logo" src="/images/logo.png?1303090162" style="margin-left:10px; padding-bottom:15px;" />

In console:

> MyApp::Application.config.action_controller
#<OrderedHash {… :asset_host=>"http://localhost:3000", …}>

I need the image_tag to create a full path url because it will be showing up in an email.

Answer 1

I was wrong before. This is the solution you need (until rails 3.1 where the asset_host configurations become unified):

config.action_mailer.asset_host = "http://localhost:3000"
