ActionMailer Previews are not accessible

[nunosilva800]

With Rails 4.1 we now have mailer previews (http://edgeguides.rubyonrails.org/4_1_release_notes.html#action-mailer-previews), but I'm getting a 404: ActionController::RoutingError (Page not found)

Commenting comfy_route :cms, :path => '/', :sitemap => true in routes.rb works, so this is means sofa is blocking access to it.

Note: also tried
config.railties_order = [ :all, ComfortableMexicanSofa::Engine ]
without success.

I don't know how mailer preview routing works, but I'm guessing it gets clobbered by the catch-all route.
I'd start digging to figure out how ActionMailer injects routes for preview. If anything, it should be possible to redefine it for your app.

Edit: Also, also that wiki is not relevant for newer versions of CMS where you define globbing routing manually. Before CMS routing was magically injected and sometimes it would make your own routes inaccessible. So I'm thinking that ActionMailer magically injects routes at the end of your app routes. So any globbing route will break it.

Yeah, it's Rails thing: rails/rails#17895

For now you can just redefine those routes before the CMS content serving route.

Cool, thanks!
