`parent_mailer` config option boot error

Open eneagoe opened this issue 2 years ago • 0 comments

Environment

  • Ruby 3.2.2
  • Rails 7.1.2
  • Devise 4.9.3

Current behavior

Setting up the parent_mailer options with

config.parent_mailer = "ApplicationMailer"

prevents the application from starting up - there's a class loading issue, apparently:

=> Booting Puma
=> Rails 7.1.2 application starting in development
=> Run `bin/rails server --help` for more startup options

Trying to get around this issue by defining the class in config/initializers/devise.rb with something like

class ApplicationMailer < ActionMailer::Base
end

will start the app correctly, but it won't work as expected - none of the before actions defined in app/mailers/application_mailer.rb will apply.

Expected behavior

Setting up parent_mailer should at the very least not crash the booting process.
