How to include image in mail devise

To include an image in a mail sent using Devise, you can use the image_tag method provided by Rails. Here are a few ways to do it:

Method 1: Using image_tag

In your mailer view (e.g., user_mailer.html.erb), you can use the image_tag method to include an image:

<%= image_tag "path/to/image.jpg", alt: "Image description" %>

Replace "path/to/image.jpg" with the actual path to your image file.

Method 2: Using content_tag

You can also use the content_tag method to include an image:

<%= content_tag :img, "", src: "path/to/image.jpg", alt: "Image description" %>

This method is similar to image_tag, but gives you more control over the HTML attributes.

Method 3: Using a URL

If your image is hosted elsewhere (e.g., on a CDN), you can include it in your mail by using a URL:

<%= link_to image_url("path/to/image.jpg"), target: "_blank" %>

This will create a link to the image, which will be displayed in the email.

Tips and Variations

• Make sure to use the correct path to your image file. If your image is located in the app/assets/images directory, you can use image_path("image.jpg") to generate the correct URL.
• You can also use image_tag with other options, such as size or style, to customize the image display.
• If you're using a Rails 4 or later, you can use the asset_path method to generate the correct URL for your image.
• If you're using a Rails 3, you can use the image_path method to generate the correct URL for your image.
