Action mailer gmail

To set up an Action Mailer to send emails using Gmail, you'll need to follow these steps:

Step 1: Set up your Gmail account

• Create a new Gmail account or use an existing one.
• Enable "Less secure app access" in your Google Account settings. This is required for Action Mailer to work with Gmail.

Step 2: Create an Action Mailer

• In your Rails application, create a new file called application_mailer.rb in the app/mailers directory.
• Add the following code to the file:

  class ApplicationMailer < ActionMailer::Base
  default from: '[email protected]'
  default to: '[email protected]'
  default subject: 'Your Subject'
  end

  Replace [email protected] with your Gmail address, [email protected] with the recipient's email address, and Your Subject with the subject of the email.

Step 3: Configure Action Mailer to use Gmail

• In your config/environments/production.rb file, add the following code:

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
  address:              'smtp.gmail.com',
  port:                 587,
  domain:               'smtp.gmail.com',
  user_name:            '[email protected]',
  password:             'your_password',
  authentication:       'plain',
  enable_starttls_auto: true
  }

  Replace [email protected] with your Gmail address and your_password with your Gmail password.

Step 4: Send an email using Action Mailer

• Create a new file called user_mailer.rb in the app/mailers directory.
• Add the following code to the file:

  class UserMailer < ApplicationMailer
  def welcome_email(user)
    @user = user
    mail to: user.email, subject: 'Welcome to our application!'
  end
  end

  This code defines a welcome_email method that sends an email to the user with a welcome message.

Step 5: Test your Action Mailer

• Run the following command in your terminal:

  rails c

  This will open a Rails console.

• Run the following code to send an email:

  UserMailer.welcome_email(User.first).deliver_now

  This will send an email to the first user in your database.

That's it! You should now have an Action Mailer set up to send emails using Gmail.
