Usage

Sending Notifications

The notify() function is your gateway to all notification types.

Basic Email Notification

from magic_notifier.notifier import notify

user = User.objects.get(email="testuser@localhost")
subject = "Welcome!"
notify(["email"], subject, [user], final_message="Welcome to our platform!")

SMS Notification with Template

notify(["sms"], "Account Alert", [user], template="account_alert")

Multi-Channel Notification

notify(["email", "sms"], "System Update", [user], final_message="The system will be down for maintenance.")

WhatsApp Notification

notify(["whatsapp"], "Welcome", [user], final_message="Hello! This is a WhatsApp test message.")

Telegram Notification

notify(["telegram"], "Welcome", [user], final_message="Hello! This is a Telegram test message.")

Passing Context to Templates

You can pass additional context to your templates via the context argument, note that the user object is automatically passed:

context = {
    "discount": 20
}
notify(["email"], "Special Offer", [user], template="special_offer", context=context)

In the template:

{% block content %}
<p>Hi {{ user.first_name }},</p>
<p>We are excited to offer you a {{ discount }}% discount on your next purchase!</p>
{% endblock %}

Overriding Gateways

You can override default gateways directly when sending notifications:

Override Email Gateway

notify(["email"], "Custom Email Gateway", [user], final_message="This uses a custom email gateway.", email_gateway="custom_gateway")

Override SMS Gateway

notify(["sms"], "Custom SMS Gateway", [user], final_message="This uses a custom SMS gateway.", sms_gateway="custom_sms_gateway")

Override WhatsApp Gateway

notify(["whatsapp"], "Custom WhatsApp Gateway", [user], final_message="This uses a custom WhatsApp gateway.", whatsapp_gateway="custom_whatsapp_gateway")

Override Telegram Gateway

notify(["telegram"], "Custom Telegram Gateway", [user], final_message="This uses a custom Telegram gateway.", telegram_gateway="custom_telegram_gateway")

Template Creation and Resolution

When using templates, Django Magic Notifier looks for specific files depending on the notification channels. The template value designates a folder, not a file. Files are checked in the following order for each channel:

• Email: email.mjml -> email.html -> email.txt
• SMS: sms.txt
• WhatsApp: whatsapp.txt -> sms.txt
• Telegram: telegram.txt -> sms.txt

If a file is not found, the next file in the sequence is checked. If no files are found, an error is raised.

Example

Suppose notify() is called as follows:

notify(["telegram"], "Welcome", [user], template="welcome")

The following files will be checked in order:

1. notifier/welcome/telegram.txt
2. notifier/welcome/sms.txt

Ensure that at least one of these files exists in your templates directory.

Advanced Features

Sending Files

Attach files to your notifications:

files = ["/path/to/file.pdf"]
notify(["email"], "Invoice", [user], final_message="Your invoice is attached.", files=files)

Sending to Specific Receiver Groups

The notify() function supports predefined values for the receivers argument to target specific user groups:

Sending to Admin Users

notify(["email"], "Admin Alert", "admins", final_message="This is a message for all admin users.")

Sending to Staff Users

notify(["email"], "Staff Notification", "staff", final_message="This message is for all staff members.")

Sending to All Users

notify(["email"], "Global Announcement", "all", final_message="This is a message for all users.")

Sending to Non-Staff Users

notify(["email"], "Non-Staff Update", "all-staff", final_message="This message is for users who are not staff.")

Sending to Non-Admin Users

notify(["email"], "User Alert", "all-admins", final_message="This is a message for all users except admins.")

Asynchronous Processing

Enable threaded notifications for better performance:

notify(["sms"], "Alert", [user], final_message="This is a test.", threaded=True)
