Question

I previously had a test mailer working (based on the RailsGuides tutorial). When I integrate PostageApp gem and inherit from PostageApp, I get this:

@message="Message layout Provided Message Template is not found., Content can't be blank"

Answer 1

Seems that you’re not sending any content over. You are also specifying a postageapp_template that doesn’t exists in your PostageApp project for some reason.

Try figuring out what exactly is being sent. In your test (you have tests, right?) have something like this:

email = ActionMailer::Base.deliveries.last
raise email.arguments_to_send.to_yaml

You’ll see the actual payload. That should give you a pretty good idea what’s missing.
