Mailer error missing template
Try adding layout
class UserMailer < ActionMailer::Base default from: "from@example.com" layout "mailer" def mailer(user) @user = user mail(to: @user.email, subject: 'Test') endend
Could you publish a minimalist Github repository reproducing your error?
You may try to generate your mailer in order to check you are not forgetting something:
bundle exec rails generate mailer mailer_classname mailer_viewname
In your case:
bundle exec rails generate mailer user_mailer mailer
class UserMailer < ActionMailer::Base default from: "from@example.com" layout "mailer" def mailer(user) @user = user mail(to: @user.email, subject: 'Test') endendAdd a html layout under layout#
mailer.html.erb
<!DOCTYPE html><html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <style> /* Email styles need to be inline */ </style> </head> <body> <%= yield %> </body></html>Add text layout under layout #
mailer.text.erb
<%= yield %>Use preview to check your email based on your test framework.
