Full url for an image-path in Rails 3

You can also set CarrierWave’s asset_host config setting like this:

# config/initializers/carrierwave.rb
CarrierWave.configure do |config|
  config.storage = :file
  config.asset_host = ActionController::Base.asset_host
end

This ^ tells CarrierWave to use your app’s config.action_controller.asset_host setting, which can be defined in one of your config/envrionments/[environment].rb files. See here for more info.

Or set it explicitly:

  config.asset_host="http://example.com"

Restart your app, and you’re good to go – no helper methods required.

* I’m using Rails 3.2 and CarrierWave 0.7.1
