Overview: Broadcast to Role Groups Module

Purpose

The Broadcast to Role Groups module is designed to streamline communication within an application by enabling efficient message distribution to predefined user groups. This module eliminates the need for manual selection of individual users, allowing administrators or developers to send targeted messages to specific roles such as “All Parents” or “All Tutors”.

Benefits

• Efficiency: Automates the process of broadcasting messages to multiple users simultaneously, saving significant time compared to manual sending.

• Enhanced Communication: Facilitates effective engagement by enabling tailored messages for different user groups, ensuring relevant information is received by appropriate recipients.

• Flexibility: Allows creation and management of custom role groups, adapting to various organizational needs and structures.

• Predefined Roles Integration: Supports integration with existing user roles within the application, enhancing workflow efficiency through streamlined processes.

• Increased Engagement: By delivering personalized messages, it boosts user interaction and satisfaction, leading to higher engagement rates.

• Audit Trail: Provides a comprehensive log of message distribution activities, aiding in tracking and accountability.

Usage Scenarios

1. User Group Notifications: Sending updates or critical information such as meeting reminders or event notifications directly to relevant groups.

2. Communication Coordination: Coordinating group activities, such as schedule changes for tutors or important announcements for parents.

3. Event Management: Informing specific groups about events like parent-teacher meetings or special sessions.

4. System-Wide Announcements: Broadcasting system updates, maintenance alerts, or policy changes to all users or select roles.

5. Bulk Campaigns: Conducting marketing or promotional campaigns through targeted messaging to specific user segments.

6. Custom Testing and Feedback: Sending personalized test notifications or gathering feedback from particular groups for product improvement.

This module is a powerful tool for developers looking to enhance communication efficiency within their applications, offering flexibility, scalability, and robust features tailored to meet diverse organizational needs.

Feature Name: User Role Groups

This feature allows administrators to define and manage role groups based on user roles (e.g., Parents, Tutors). Each group can be targeted individually or in combination with others for broadcasts.

Feature Name: Message Templates

Predefined message templates provide consistent communication across multiple channels. They can include placeholders for dynamic content and are customizable to meet specific needs.

Feature Name: Broadcast History

Maintains a record of all broadcast activities, including date, time, target groups, and message details. This feature is essential for auditing, tracking, and debugging purposes.

Feature Name: Targeting Criteria

Enables precise targeting by allowing messages to be sent based on user attributes such as location, activity level, or specific tags. This ensures that only relevant users receive the message.

Feature Name: Scheduling

Messages can be scheduled for future delivery at specified times, allowing for automated and timely communication without manual intervention.

Feature Name: API Integration

The module offers an API interface to integrate broadcast functionality into external systems or services, enabling programmatic control over message distribution.

Here’s the technical documentation for the “Broadcast to Role Groups” module:

Broadcast to Role Groups Module

Overview

This module allows sending targeted messages to specific user role groups such as “Parents”, “Tutors”, or “Admins”. It includes an API endpoint for message broadcasting, a React UI component for message composition and sending, and data validation using Pydantic.

Components

1. FastAPI Endpoint (Python)

from fastapi import APIRouter, Depends, HTTPException
from typing import List
from pydantic import BaseModel

router = APIRouter()

class Message(BaseModel):
    content: str
    sender_id: int
    subject: str
    broadcast_type: str  # Could be "email", "notification", etc.
    recipient_role_groups: List[str]

@router.post("/api/send-message")
async def send_message(message: Message):
    """Broadcast message to specified role groups."""
    try:
        # Implementation logic here (e.g., database interactions)
        return {"status": "success", "message_id": 123}
    except Exception as e:
        raise HTTPException(status_code=500, detail=str(e))

2. Node.js Endpoint

const express = require('express');
const router = express.Router();

router.post('/api/send-message', async (req, res) => {
    const { message } = req.body;
    // Implementation logic here (e.g., database interactions)
    res.status(200).json({ status: 'success', messageId: 123 });
});

module.exports = router;

3. React UI Component

import React, { useState } from 'react';

const BroadcastMessage = () => {
    const [messageContent, setMessageContent] = useState('');
    const [recipientRoleGroups, setRecipientRoleGroups] = useState(['All Parents']);
    const [subject, setSubject] = useState('');

    const handleSubmit = async (e) => {
        e.preventDefault();
        try {
            const response = await fetch('/api/send-message', {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify({
                    content: messageContent,
                    subject: subject,
                    sender_id: 1, // Example sender ID
                    recipient_role_groups: recipientRoleGroups
                })
            });
            const data = await response.json();
            alert(data.status);
        } catch (error) {
            console.error('Error:', error);
        }
    };

    return (
        <form onSubmit={handleSubmit}>
            <div>
                <label>Subject:</label>
                <input 
                    type="text" 
                    value={subject}
                    onChange={(e) => setSubject(e.target.value)}
                />
            </div>
            <div>
                <label>Message Content:</label>
                <textarea
                    value={messageContent}
                    onChange={(e) => setMessageContent(e.target.value)}
                ></textarea>
            </div>
            <div>
                <label>Recipient Role Groups:</label>
                <select 
                    multiple
                    value={recipientRoleGroups}
                    onChange={(e) => setRecipientRoleGroups(Array.from(e.target.selectedOptions, option => option.value))}
                >
                    <option value="All Parents">All Parents</option>
                    <option value="All Tutors">All Tutors</option>
                    <option value="Admins">Admins</option>
                </select>
            </div>
            <button type="submit">Send Message</button>
        </form>
    );
};

export default BroadcastMessage;

4. Pydantic Data Schema

from pydantic import BaseModel
from typing import List

class Recipient(BaseModel):
    role_group: str
    user_ids: List[int] = []  # Optional list of specific user IDs

class MessageSchema(BaseModel):
    content: str
    sender_id: int
    subject: str
    broadcast_type: str  # Options like "email", "notification"
    recipient_role_groups: List[str]
    custom_recipients: List[Recipient] = []  # Optional custom recipients

Usage Examples

Using the FastAPI Endpoint:

curl -X POST "http://localhost:8000/api/send-message" \
-H "Content-Type: application/json" \
-d '{"content":"Meeting reminder tomorrow","subject":"Important Update","sender_id":1,"broadcast_type":"notification","recipient_role_groups":["All Tutors"]}'

Using the React Component:

• Open the React application.
• Fill in the subject, message content, and select recipient role groups.
• Click “Send Message” to broadcast the notification.

This module provides a robust way to send targeted messages to specific user groups efficiently.
