Introduction to ActionMailer:‍ Sending Emails⁣ in Rails

⁣ ‍

Sending emails is ​a common task‍ in⁣ many web ‍applications, and Ruby on Rails provides a powerful and‍ convenient way ​to ‌achieve this using ⁣ActionMailer.

‍ ⁤ ‍

What is ⁤ActionMailer?

⁢

ActionMailer is ‌a built-in ⁢library‍ in Ruby on ‍Rails that simplifies the‍ process ​of‍ sending ​emails. It provides⁣ a framework for creating ⁤mailers and⁤ composing email templates ⁣using‌ HTML and plain text.

⁢ ‍
⁢ ⁢ ‌

Setting⁣ Up ⁤ActionMailer

⁣ ⁤

To ⁤start‍ using ActionMailer, you need to have a Rails​ application ‍set⁣ up. Once you‌ have your application ready, you’ll need to define‍ a mailer class that inherits from ActionMailer::Base.

‌⁢

class UserMailer <‌ ActionMailer::Base

  ​default from: 'notifications@example.com'

 

  def welcome_email(user)

  ‍ ‌ @user = user

  ⁣⁤  mail(to: @user.email, ​subject: 'Welcome to My App!')

  end

end

   ⁣ 

⁣ ⁣⁤
‍

In the above example, we⁣ define a UserMailer class⁣ that will‌ be responsible for sending ⁢a welcome email‍ to⁤ a ⁣user. The welcome_email method takes a ‍user object as ⁤a⁣ parameter and⁤ sets ‍the @user instance variable, which‍ can be⁢ accessed within the ‍email template.

​

Creating Email Templates

⁣

ActionMailer⁣ provides a convenient way to create email templates using both ‌HTML and ‌plain text formats. ​By default, ⁤it will⁤ look for template files with the same name as your ⁢mailer ‌method in the app/views/user_mailer/ ​directory.

⁤

‌ ‌

For example, to ​create the welcome email template, we’ll ​create two ‍files: ⁢welcome_email.html.erb​ and welcome_email.text.erb.

‌
⁣ ⁤

welcome_email.html.erb:

‌ ⁣ ⁤

Welcome to My App,⁢ <%= @user.name %>!

Sending ‌Emails

‍⁢

To send the ‌welcome email to a user,⁣ we can simply⁣ call ⁢the ⁤welcome_email ‌method⁣ on our UserMailer class ‍and​ pass the ⁤user object.

‌ ​
⁣ ⁢

UserMailer.welcome_email(user).deliver_now

 ‍   ​

‍ ⁣

‍

The deliver_now method‌ sends ‌the email immediately. You‌ can also use deliver_later⁢ to ⁤enqueue‍ the email ⁤sending job for background ⁤processing.

​⁢

Conclusion

⁤

ActionMailer‍ makes‍ it easy‍ to send ‌emails in ⁢Ruby on‌ Rails applications. By creating⁤ mailer classes, defining email​ templates, and ​invoking the appropriate methods,⁤ you⁤ can‍ efficiently handle email sending ‍within your application.

‍
​

Remember to configure ⁢the⁣ email⁢ settings in your Rails ⁣application’s config/environments files to specify the ‍SMTP server or‍ other email delivery options.
