Question 1

Which command generates a new mailer in a Rails application?

Accepted Answer

The rails generate mailer command (or rails g mailer) creates a new mailer with the corresponding class in app/mailers, views in app/views, and test files. This command follows Rails conventions and automatically generates the file structure needed to send emails.

Question 2

Which class must all mailers inherit from in a Rails application?

Accepted Answer

All Rails mailers inherit from ApplicationMailer, which itself inherits from ActionMailer::Base. ApplicationMailer is created by default in app/mailers and allows defining common configurations for all mailers in the application, such as the default layout or sender address.

Question 3

In which directory are email view templates located in a Rails application?

Accepted Answer

Email view templates are located in app/views/mailer_name/. Each mailer method corresponds to a template (for example welcome_email.html.erb and welcome_email.text.erb). Rails automatically looks for templates matching the mailer method name.
