## API Reference (FastAPI)

The following FastAPI endpoint allows the creation of new learning paths:

```python
from fastapi import APIRouter, Depends, HTTPException
from typing import List
from ..models.learning_path import LearningPathCreate, LearningPathResponse
from ..database import SessionLocal, engine
import sqlalchemy as sql

router = APIRouter()

# SQLAlchemy model for learning path (assumed to exist)
learning_path_table = sql.Table(
    "learning_paths",
    engine.metadata,
    sql.Column("id", sql.Integer, primary_key=True),
    sql.Column("course_id", sql.String),
    sql.Column("module_id", sql.String),
    sql.Column("title", sql.String),
    sql.Column("description", sql.Text),
    sql.Column("modules", sql.JSON),
)

def get_db():
    db = SessionLocal()
    try:
        yield db
    finally:
        db.close()

@router.post("/learning-paths/", response_model=LearningPathResponse)
async def create_learning_path(
    learning_path: LearningPathCreate,
    db: SessionLocal = Depends(get_db),
):
    """
    Create a new learning path by sequencing multiple courses/modules.
    """
    try:
        # Insert into the database
        insert_stmt = sql.insert(learning_path_table).values(**learning_path.dict())
        result = db.execute(insert_stmt)
        
        # Get the inserted ID
        created_id = result.inserted_primary_key[0]
        
        return {
            "id": created_id,
            **learning_path.dict(),
        }
    
    except Exception as e:
        raise HTTPException(
            status_code=500,
            detail=str(e),
        )

Client-Side Integration (React)

Here’s a React component snippet for displaying learning paths:

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

interface LearningPath {
  id: string;
  title: string;
  description: string;
  modules: Module[];
}

interface Module {
  moduleId: string;
  title: string;
  description: string;
  prerequisites?: string[];
  difficulty: 'Beginner' | 'Intermediate' | 'Advanced';
}

const LearningPathsList = () => {
  const [learningPaths, setLearningPaths] = useState<LearningPath[]>([]);

  useEffect(() => {
    // Replace with your API call
    fetch('/api/learning-paths/')
      .then((response) => response.json())
      .then((data) => setLearningPaths(data))
      .catch((error) => console.error('Error fetching learning paths:', error));
  }, []);

  return (
    <div className="container mx-auto p-4">
      <h1 className="text-3xl font-bold mb-6">Learning Paths</h1>
      <div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
        {learningPaths.map((path) => (
          <div key={path.id} className="bg-white rounded-lg shadow-md p-4 hover:shadow-lg transition-shadow duration-300"):
            <h2 className="text-xl font-semibold mb-2">{path.title}</h2>
            <p className="text-gray-600 mb-4">{path.description}</p>
            <div className="space-y-2">
              {path.modules.map((module) => (
                <div key={module.moduleId} className="bg-blue-50 p-3 rounded">
                  <h3 className="font-medium text-blue-800">{module.title}</h3>
                  <p className="text-sm text-gray-600">{module.description}</p>
                </div>
              ))}
            </div>
          </div>
        ))}
      </div>
    </div>
  );
};

export default LearningPathsList;

Data Models (Pydantic)

Here’s the Pydantic schema for learning paths:

from pydantic import BaseModel, Field
from typing import List, Optional

class CourseModule(BaseModel):
    moduleId: str = Field(..., description="Unique identifier of the module")
    title: str = Field(..., description="Title of the module")
    description: str = Field(..., description="Description of the module")
    prerequisites?: List[str] = Field(
        None,
        description="List of prerequisite modules (optional)",
    )
    difficulty: str = Field(
        ...,
        description="Difficulty level",
        enum=["Beginner", "Intermediate", "Advanced"],
    )

class LearningPathCreate(BaseModel):
    course_id: str = Field(..., description="Course identifier")
    module_id: str = Field(..., description="Module identifier")
    title: str = Field(..., description="Title of the learning path")
    description: str = Field(..., description="Description of the learning path")
    modules: List[CourseModule] = Field(
        ...,
        description="List of modules in the learning path",
    )

class LearningPathResponse(LearningPathCreate):
    id: int = Field(..., description="Unique identifier of the learning path")

This documentation provides a comprehensive overview of how to create and manage learning paths using the Learning Path Builder module. The FastAPI endpoint handles creating new sequences, while the React component demonstrates how to display these learning paths in a user-friendly manner.

Learning Path Builder Module Documentation

Summary

The Learning Path Builder module allows you to sequence multiple courses or modules into tracks. It is designed to help users create structured learning paths, manage prerequisites, and track user progress through a series of courses.

Target User

• Developers integrating educational content management systems.
• Curriculum designers building structured learning pathways.
• Platform administrators managing course dependencies.

Related Modules

The Learning Path Builder module integrates with the following modules:

1. Course Catalog: Manages the list of available courses and modules.
2. User Progress Tracker: Tracks user progress through various courses and modules.
3. Enrollment System: Handles user enrollment in courses and learning paths.
4. Reporting Tools: Provides analytics on user completion rates and path progression.
5. Certificate Manager: Issues certificates upon successful completion of learning paths.

Use Cases

1. Creating a Basic Learning Path

• Scenario: A user wants to create a simple learning path with multiple courses.
• Steps:
  • Add courses from the Course Catalog to the learning path.
  • Save the sequence in the Learning Path Builder.
  • Users can then enroll in the path through the Enrollment System.

2. Adding Prerequisites

• Scenario: A user wants to enforce prerequisites for advanced courses.
• Steps:
  • Use the Learning Path Builder to set prerequisite courses or modules.
  • When a user tries to enroll, the Enrollment System checks if they have completed the prerequisites.
  • If not, enrollment is blocked.

3. Dynamic Content Delivery

• Scenario: A user completes one learning path and automatically enrolls in another.
• Steps:
  • Set up completion triggers in the Learning Path Builder.
  • Integrate with the Enrollment System to automatically enroll users in new paths upon completion.

4. Tracking Completion Across Platforms

• Scenario: Users complete courses on different platforms but need a centralized completion record.
• Steps:
  • Use the User Progress Tracker to sync completion data across platforms.
  • The Reporting Tools can then generate comprehensive reports.

5. Third-party Integration

• Scenario: Integrate with external Learning Management Systems (LMS) or Customer Relationship Management (CRM) tools.
• Steps:
  • Set up webhooks in the Learning Path Builder to notify third-party systems of progress updates.
  • Use REST APIs provided by the third-party tools for user authentication and enrollment.

Integration Tips

1. Webhook Setup:

   • Integrate webhooks between the Learning Path Builder and other modules (e.g., Enrollment System) to handle events like course completion or enrollment changes.

2. Middleware Implementation:

   • Implement a middleware service to mediate requests between different modules, ensuring smooth communication and data flow.

3. Environment Variables:

   • Use environment variables to store configuration settings for the Learning Path Builder, such as API keys or database connections.

4. RESTful APIs:

   • Develop RESTful APIs for module-to-module communication, adhering to standards like HTTP methods (GET, POST, PUT, DELETE) and JSON payloads.

5. Error Handling:

   • Implement robust error handling in APIs to manage unexpected scenarios, such as failed prerequisite checks or invalid enrollments.

Configuration Options

The following configuration options are available for the Learning Path Builder module:

Summary

The Learning Path Builder module is a powerful tool for creating and managing structured learning paths. By integrating with related modules like the Course Catalog, User Progress Tracker, and Enrollment System, it provides a robust solution for curriculum design and user progression tracking.
