Care SMS - Backend Configuration for Django Apps

Care SMS supports multiple SMS backends for sending messages. Each backend is designed for specific use cases like testing, development, or production. Here's how you can configure and use each backend in a Django project:

---

1. Setting Up the Backend

To configure an SMS backend in a Django app, add the SMS_BACKEND setting in your settings.py file.

Example:

# settings.py
SMS_BACKEND = 'sms.backends.<backend_module>.<BackendClass>'

---

2. Dummy Backend

The Dummy Backend does nothing with the messages and is useful for testing.

Configuration:

# settings.py
SMS_BACKEND = 'sms.backends.dummy_backend.DummyBackend'

Usage:

from sms import send_text_message

send_text_message('Test Message', 'Sender', ['Recipient'])

---

3. LocMem Backend

The LocMem Backend stores messages in an in-memory outbox, ideal for testing without external dependencies.

Configuration:

# settings.py
SMS_BACKEND = 'sms.backends.locmem_backend.LocMemBackend'

Accessing the Outbox:

from sms.backends.locmem_backend import outbox

print(outbox)  # List of sent messages

Usage:

from sms import send_text_message

send_text_message('Test Message', 'Sender', ['Recipient'])

---

4. Console Backend

The Console Backend writes messages to the console or a custom stream. This backend is useful during development.

Configuration:

# settings.py
SMS_BACKEND = 'sms.backends.console_backend.ConsoleBackend'

Usage:

from sms import send_text_message

send_text_message('Test Message', 'Sender', ['Recipient'])

---

5. File-Based Backend

The File-Based Backend saves messages to files in a specified directory, useful for debugging or lightweight persistence.

Configuration:

# settings.py
SMS_BACKEND = 'sms.backends.file_backend.FileBackend'
SMS_FILE_PATH = '/path/to/log/directory'

Usage:

from sms import send_text_message

send_text_message('Test Message', 'Sender', ['Recipient'])

---

6. MessageBird Backend

The MessageBird Backend sends SMS via the MessageBird API. Requires an API key.

Configuration:

# settings.py
SMS_BACKEND = 'sms.backends.messagebird_backend.MessageBirdBackend'
MESSAGEBIRD_ACCESS_KEY = 'your_messagebird_access_key'

Usage:

from sms import send_text_message

send_text_message('Test Message', 'Sender', ['Recipient'])

---

7. Twilio Backend

The Twilio Backend sends SMS via the Twilio API. Requires account credentials.

Configuration:

# settings.py
SMS_BACKEND = 'sms.backends.twilio_backend.TwilioBackend'
TWILIO_ACCOUNT_SID = 'your_account_sid'
TWILIO_AUTH_TOKEN = 'your_auth_token'

Usage:

from sms import send_text_message

send_text_message('Test Message', 'Sender', ['Recipient'])

---

8. AWS SNS Backend

The AWS SNS Backend sends SMS via AWS SNS. Requires AWS credentials and configuration.

Configuration:

# settings.py
SMS_BACKEND = 'sms.backends.aws_backend.SnsBackend'
AWS_SNS_REGION = 'your_region'
AWS_SNS_ACCESS_KEY_ID = 'your_access_key_id'
AWS_SNS_SECRET_ACCESS_KEY = 'your_secret_access_key'
AWS_SNS_SENDER_ID = 'your_sender_id'
AWS_SNS_SMS_TYPE = 'Transactional'  # or 'Promotional'

Usage:

from sms import send_text_message

send_text_message('Test Message', 'Sender', ['Recipient'])

---

Sending SMS

Once configured, use the send_text_message function to send SMS:

from sms import send_text_message

send_text_message('Hello, World!', 'SenderID', ['+1234567890'])

This function uses the configured backend automatically.
