Auto mail notification after expire date from database

To send automatic mail notifications after an item expires from a database, you'll need to set up a few things:

Database: You'll need a database that stores the expiration dates and other relevant information about the items. For example, you could use a relational database like MySQL or PostgreSQL.
Scripting language: You'll need a scripting language like Python, PHP, or Ruby to interact with the database and send emails. You can use a scheduling tool like cron or a task scheduler like Windows Task Scheduler to run the script at regular intervals.
Email service: You'll need an email service like Gmail, Sendgrid, or Mailgun to send the notifications. You'll need to set up an account with the email service and obtain an API key or credentials.
Notification script: You'll need to write a script that:
- Connects to the database and retrieves the list of items that have expired.
- Sends an email notification to the relevant parties (e.g., the item owner, a manager, or a customer) using the email service.

Here's a high-level example of how you could set this up using Python and MySQL:

Database schema:

CREATE TABLE items (
  id INT PRIMARY KEY,
  name VARCHAR(255),
  expiration_date DATE,
  owner_email VARCHAR(255)
);

Python script:

import mysql.connector
import smtplib
from email.mime.text import MIMEText

# Database connection settings
db_host = 'localhost'
db_user = 'your_username'
db_password = 'your_password'
db_name = 'your_database'

# Email service settings
email_service = 'gmail'
email_username = 'your_email_username'
email_password = 'your_email_password'

# Connect to the database
cnx = mysql.connector.connect(
    user=db_user,
    password=db_password,
    host=db_host,
    database=db_name
)
cursor = cnx.cursor()

# Retrieve the list of expired items
query = "SELECT * FROM items WHERE expiration_date <= CURDATE()"
cursor.execute(query)
expired_items = cursor.fetchall()

# Send email notifications
for item in expired_items:
    item_name = item[1]
    item_owner_email = item[3]
    expiration_date = item[2]

    # Create the email message
    msg = MIMEText(f"Item '{item_name}' has expired on {expiration_date}.")
    msg['Subject'] = f"Item Expiration Notification: {item_name}"
    msg['From'] = email_username
    msg['To'] = item_owner_email

    # Send the email using the email service
    if email_service == 'gmail':
        server = smtplib.SMTP('smtp.gmail.com', 587)
        server.starttls()
        server.login(email_username, email_password)
        server.sendmail(email_username, item_owner_email, msg.as_string())
        server.quit()
    elif email_service == 'sendgrid':
        # Use the Sendgrid API to send the email
        pass
    elif email_service == 'mailgun':
        # Use the Mailgun API to send the email
        pass

# Close the database connection
cnx.close()

Scheduling the script:

You can use a scheduling tool like cron or a task scheduler like Windows Task Scheduler to run the script at regular intervals (e.g., daily, weekly, or monthly). This will ensure that the script runs automatically and sends notifications to the relevant parties.

Remember to replace the placeholders (your_username, your_password, your_email_username, your_email_password, etc.) with your actual database credentials and email service settings.
