Actionmailer mail
Action Mailer!
Action Mailer is a part of the Ruby on Rails framework that allows you to send emails from your application. It's a way to send emails programmatically, without having to manually write the email content and send it using a mail client.
Here's a basic overview of how Action Mailer works:
- Mailers: In your Rails application, you create a mailer class that inherits from
ActionMailer::Base
. This class defines the email templates and the logic for sending emails. - Email Templates: You create email templates in your mailer class, which define the content of the email. These templates are written in ERb (Embedded Ruby) and can include dynamic data from your application.
- Delivery Methods: Action Mailer provides several delivery methods for sending emails, such as SMTP, Sendmail, and Mailgun. You can configure the delivery method in your
config/environments/*.rb
files. - Sending Emails: To send an email, you create an instance of your mailer class and call the
deliver
method. This method sends the email using the configured delivery method.
Here's an example of a simple mailer class:
# app/mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
default from: '[email protected]'
def welcome_email(user)
@user = user
mail to: user.email, subject: 'Welcome to our application!'
end
end
In this example, the UserMailer
class has a welcome_email
method that sends an email to the user with a welcome message. The @user
instance variable is set to the user object, and the email is sent using the mail
method.
To send an email using this mailer class, you would do something like this:
# app/controllers/users_controller.rb
class UsersController < ApplicationController
def create
user = User.new(params[:user])
UserMailer.welcome_email(user).deliver
redirect_to root_url, notice: 'Email sent successfully!'
end
end
In this example, the create
action of the UsersController
creates a new user and sends a welcome email using the UserMailer
class.
Action Mailer provides many features and options for customizing your email sending, such as:
- Layouts: You can define a layout for your emails, which allows you to customize the overall design and structure of the email.
- Partials: You can use partials to reuse common email content, such as headers and footers.
- Attachments: You can attach files to your emails using the
attachments
method. - CC and BCC: You can specify CC and BCC recipients using the
cc
andbcc
methods. - Delivery Options: You can customize the delivery options, such as the email subject, from address, and reply-to address.
Overall, Action Mailer is a powerful tool for sending emails in your Rails application, and it provides a lot of flexibility and customization options.
