My entire app is https, no http.
If add the following to any of the views
I get a \"edit user\" linked to
https://localhost:3000/user/2/edit
Editing my config/environments/development file with
host = "hostaddress.io" config.action_mailer.default_url_options = { host: host, protocol: 'https' }
worked for me on Rails 4.2.2.
