Cross-Course Navigation

The Cross-Course Navigation module is designed to enhance the user experience for students enrolled in multiple courses by providing seamless navigation between different enrollments. This core functionality simplifies the process of switching between courses, allowing users to manage their academic workload efficiently.

Purpose

The primary purpose of this module is to enable students to easily switch between multiple course enrollments within a single interface. It eliminates the need for manual navigation and reduces cognitive load by providing a unified view of all enrolled courses.

Benefits

Enhanced User Experience: Students can quickly access any of their enrolled courses without navigating through multiple login processes or separate interfaces.
Improved Productivity: By streamlining course switching, this module helps students focus on their academic tasks without unnecessary distractions.
Unified Access Point: The module acts as a central hub, allowing students to view and manage all their enrollments in one place.

Usage Scenarios

Dashboard Integration: Students can see an overview of all their enrolled courses on a dashboard, with easy access to each course via links or buttons.
Course Switcher Dropdown: A dropdown menu or similar interface allows students to select the desired course for navigation.
Quick Access Links: Prominent placement of quick-access links or icons for frequently accessed courses.
Cross-Device Compatibility: Ensures smooth navigation across different devices, including desktops, tablets, and mobile phones.

This module is essential for any learning management system (LMS) or educational platform aiming to provide a seamless and user-friendly experience for multi-course enrollment scenarios.

Multi-Enrollment Support

This feature allows students to manage multiple course enrollments efficiently. The system integrates with the enrollment tracking API to fetch and update enrollment status in real-time. Developers can access this data via RESTful endpoints, ensuring seamless integration into the dashboard interface.

Course Switching Functionality

Quickly switch between courses using a dropdown menu or buttons located on the navigation bar. The implementation uses session management techniques, such as cookies and tokens, to maintain user context across different course environments, ensuring continuity in user experience.

The UI dynamically adapts based on the current course context. For example, breadcrumb trails update to reflect the current course, and menu options adjust accordingly. Event handlers manage context switches, triggering necessary updates to navigation elements and state management.

Audit Trail for Cross-Course Activity

Activity logs are captured using a logging mechanism that records time stamps, course IDs, user actions, and IP addresses. These logs are stored in a database for auditing purposes, supporting compliance with data protection regulations by maintaining secure and accessible audit trails.

Each feature is designed to provide developers with clear technical insights, ensuring smooth integration and maintenance within the system’s architecture.

FastAPI Endpoint (Python)

The following is a FastAPI endpoint that allows students to switch between enrolled courses.

from fastapi import APIRouter, Depends, Path
from typing import Annotated
from pydantic import BaseModel

router = APIRouter()

class Enrollment(BaseModel):
    student_id: str
    course_id: str
    status: str  # "enrolled" or "unenrolled"

@router.put(
    "/students/{student_id}/courses/{course_id}",
    summary="Switch Course Enrollment",
    description="Enroll or un-enroll a student in a specific course."
)
async def switch_enrollment(
    student_id: Annotated[str, Path],
    course_id: Annotated[str, Path],
    enrollment_status: str = Query(...),  # "enroll" or "unenroll"
    token: str = Header(...)
):
    """
    Switches the enrollment status of a student for a specific course.

    Args:
        student_id (str): The ID of the student.
        course_id (str): The ID of the course.
        enrollment_status (str): The desired enrollment status ("enroll" or "unenroll").
        token (str): Authentication token.

    Returns:
        dict: A dictionary containing the updated enrollment information.
    """
    # Assume we have a database model called CourseEnrollment
    enrollment = await CourseEnrollment.find(student_id, course_id)
    
    if enrollment_status == "enroll":
        if not enrollment:
            new_enrollment = Enrollment(
                student_id=student_id,
                course_id=course_id,
                status="enrolled"
            )
            await new_enrollment.save()
            return {"message": "Student enrolled successfully", "status": "enrolled"}
    else:  # unenroll
        if enrollment:
            await enrollment.delete()
            return {"message": "Student un-enrolled successfully", "status": "unenrolled"}

    return {"message": f"Enrollment status could not be updated", "status": "error"}

React UI Component (JavaScript)

The following is a React component that provides a UI for course switching.

import React, { useState } from 'react';
import axios from 'axios';

const CourseSwitcher = () => {
    const [courses, setCourses] = useState([]);
    const [selectedCourse, setSelectedCourse] = useState('');
    const [isLoading, setIsLoading] = useState(false);
    const [error, setError] = useState(null);

    const fetchCourses = async () => {
        try {
            const response = await axios.get('/api/courses');
            setCourses(response.data);
        } catch (err) {
            setError('Failed to fetch courses');
        }
    };

    const switchEnrollment = async () => {
        setIsLoading(true);
        setError(null);
        try {
            if (!selectedCourse) return;
            
            const response = await axios.put(
                `/api/students/${studentId}/courses/${selectedCourse}`,
                { enrollment_status: 'enroll' }
            );
            
            // Handle response
            setIsLoading(false);
            alert(response.data.message);
        } catch (err) {
            setError('Failed to switch enrollment');
            setIsLoading(false);
        }
    };

    return (
        <div>
            <h2>Course Switcher</h2>
            <select 
                value={selectedCourse}
                onChange={(e) => setSelectedCourse(e.target.value)}
            >
                {courses.map(course => (
                    <option key={course.id} value={course.id}>
                        {course.name}
                    </option>
                ))}
            </select>
            <button onClick={switchEnrollment} disabled={isLoading}>
                {isLoading ? 'Switching...' : 'Switch Course'}
            </button>
            {error && <p style={{ color: 'red' }}>{error}</p>}
        </div>
    );
};

export default CourseSwitcher;

Pydantic Data Schema

The following defines the data models for course enrollment.

from pydantic import BaseModel
from typing import Optional, Dict

class Course(BaseModel):
    id: str
    name: str
    description: Optional[str] = None
    enrollment_status: str  # "open" or "closed"

class Enrollment(BaseModel):
    student_id: str
    course_id: str
    status: str  # "enrolled" or "unenrolled"
    enrolled_at: Optional[Dict[str, str]] = None

class CourseEnrollmentResponse(BaseModel):
    message: str
    status: str
    enrollment_data: Optional[Enrollment] = None
