Add New Comment on your post notifications This notification is sent only to the post owner, unless this person turned off the notifications. A simple first step into the notifications by mail world :) The mail contains a link to user profile The link to the user profile is required to give an easy access to notifications disabling. Also having a preview for the notify_post_owner method We can `Comment.first` because it is part of the db:seeds method. So there should, in development, always be one. 2021-01-29 00:49:27 +01:00			`# Preview all emails at http://localhost:3000/rails/mailers/user_mailer`
