rails spreadsheet email attachment

To send an email with a spreadsheet attachment using Ruby on Rails, you can follow these steps:

  1. Install the necessary gems: Ensure you have the required gems installed in your Rails application. You will need the mail and spreadsheet gems. You can add them to your Gemfile and run bundle install to install them.

  2. Create the spreadsheet: Use the spreadsheet gem to create a new spreadsheet. You can define the data and format it as needed. For example, you can create a new workbook and add worksheets, rows, and cells to it.

  3. Save the spreadsheet: Once you have added the necessary data to the spreadsheet, save it to a file. You can use the write method to save the spreadsheet as a file on your system.

  4. Attach the spreadsheet to the email: Use the mail gem to create a new email message. Set the recipient, subject, and body of the email as needed. To attach the spreadsheet, use the attachments method and specify the path to the file.

  5. Send the email: Use the deliver_now method to send the email. This will deliver the email immediately. If you want to deliver the email later, you can use the deliver_later method instead.

Here is an example code snippet that demonstrates these steps:

require 'spreadsheet'
require 'mail'

# Create the spreadsheet
book = Spreadsheet::Workbook.new
sheet = book.create_worksheet
sheet[0, 0] = 'Name'
sheet[0, 1] = 'Email'
sheet[1, 0] = 'John Doe'
sheet[1, 1] = '[email protected]'

# Save the spreadsheet
file_path = 'path/to/spreadsheet.xls'
book.write(file_path)

# Attach the spreadsheet to the email
mail = Mail.new
mail.to = '[email protected]'
mail.subject = 'Spreadsheet Attachment'
mail.body = 'Please find the attached spreadsheet.'
mail.attachments[file_path] = File.read(file_path)

# Send the email
mail.deliver_now

Note: Make sure to replace 'path/to/spreadsheet.xls' with the actual path where you want to save the spreadsheet file, and '[email protected]' with the actual recipient's email address.
