Role & Permission Editor Overview

The Role & Permission Editor module is a critical tool designed to manage user access with precision, ensuring that each role within the system—such as admins, instructors, reviewers, and assistants—has the appropriate level of permissions. This module empowers administrators to define granular access controls, enhancing security and operational efficiency.

Purpose

The primary purpose of this module is to streamline the management of user roles and their corresponding permissions, allowing for a flexible and secure access control mechanism. It provides developers with the ability to:

• Assign specific permissions to predefined roles or individual users.
• Revise existing permissions as needed to adapt to changing system requirements or organizational policies.

Benefits

By utilizing the Role & Permission Editor module, organizations can achieve several key advantages:

• Enhanced Security: Implement precise access control measures, reducing the risk of unauthorized actions and data breaches.
• Compliance: Ensure adherence to internal policies and external regulations by maintaining clear and auditable permission structures.
• Simplified Management: Easily manage user permissions without granting excessive privileges, minimizing potential vulnerabilities.
• Audit Trails: Log changes in permissions for comprehensive auditing, ensuring accountability and traceability of access modifications.
• Scalability: Support the system’s growth by adding new roles and permissions as needed.

Usage Scenarios

1. Defining Roles

• Creating New Roles: Define specific roles such as “System Admin” or “Content Reviewer” to match organizational needs.
• Assigning Permissions: Attach a set of predefined permissions to each role, ensuring that users only access necessary functionalities.

2. Assigning and Revoking Permissions

• Permission Assignment: Grant or revoke specific permissions (e.g., edit content, view reports) for roles or individual users dynamically.
• Revoking Access: Temporarily or permanently remove access rights when a user changes roles or leaves the organization.

3. Auditing and Compliance

• Access Audits: Review historical permission changes to ensure compliance with policies and identify potential security issues.
• Compliance Checks: Confirm that all permissions align with legal and organizational standards, facilitating audits by regulatory bodies.

4. System Scalability

• Adapting to Growth: Introduce new roles and permissions as the system expands, ensuring continued functionality without compromising security.

The Role & Permission Editor module is an essential asset for developers aiming to maintain a secure, compliant, and efficient access control environment within their applications.

Role Management

Define, create, update, or delete roles such as Admin, Instructor, Reviewer, and Assistant. Roles determine access levels within the system.

Permission Management

Assign specific permissions to roles (e.g., view, edit, delete) for various actions like accessing modules, viewing user data, or managing settings.

Granular Permissions

Configure fine-grained access control by assigning permissions at the feature or functionality level, ensuring precise security policies.

Audit Log

Track changes made to roles and permissions with an audit log, capturing details such as who made the change and when it was made.

Sorting & Filtering

Sort and filter roles or permissions lists for easier navigation and management of large numbers of users or access levels.

Bulk Actions

Perform bulk actions on multiple roles or permissions at once, improving efficiency when managing large-scale updates.

Default Role Setup

Set up predefined default roles to streamline the configuration process and ensure consistent access control across the system.

Permissions Revocation

Revoke specific permissions from a role to tighten security or modify access levels as needed for compliance or organizational changes.

Summary:

The Role & Permission Editor module allows administrators to define granular access control for different user roles (admins, instructors, reviewers, and assistants). This module provides the ability to create, read, update, and delete roles and their associated permissions.

Technical Documentation

1. FastAPI Endpoint Example

This endpoint demonstrates how to create a new role using FastAPI.

from fastapi import APIRouter, Depends, HTTPException
from sqlalchemy.orm import Session
from typing import List
from pydantic import BaseModel
from ..models.role import Role

router = APIRouter(prefix="/roles", tags=["roles"])

# Pydantic Models
class RoleCreate(BaseModel):
    name: str
    description: str

@router.post("/", response_model=RoleResponse)
def create_role(
    role_data: RoleCreate,
    db: Session = Depends(get_db),
    current_user=Depends(oauth2_passwordBearer()),
):
    """Create a new role"""
    if not crud.role.exists(db, name=role_data.name):
        crud.role.create(db, obj_in=role_data)
        return {"message": f"Role {role_data.name} created successfully"}
    raise HTTPException(status_code=400, detail="Role already exists")

2. React UI Example

This snippet shows a React component for managing roles and permissions.

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

interface Role {
  id: string;
  name: string;
  description: string;
}

export default function RolesPage() {
  const [roles, setRoles] = useState<Role[]>([]);
  const [newRole, setNewRole] = useState({ name: "", description: "" });

  const fetchRoles = async () => {
    try {
      const response = await axios.get("/api/roles/");
      setRoles(response.data);
    } catch (error) {
      console.error("Error fetching roles:", error);
    }
  };

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    try {
      await axios.post("/api/roles/", newRole);
      setRoles([...roles, { ...newRole }]);
      setNewRole({ name: "", description: "" });
    } catch (error) {
      console.error("Error creating role:", error);
    }
  };

  return (
    <div>
      <h1>Role Management</h1>
      <form onSubmit={handleSubmit}>
        <input
          type="text"
          placeholder="Role name"
          value={newRole.name}
          onChange={(e) => setNewRole({ ...newRole, name: e.target.value })}
        />
        <input
          type="text"
          placeholder="Description"
          value={newRole.description}
          onChange={(e) =>
            setNewRole({ ...newRole, description: e.target.value })
          }
        />
        <button type="submit">Add Role</button>
      </form>
      <table>
        <thead>
          <tr>
            <th>Role Name</th>
            <th>Description</th>
            <th>Actions</th>
          </tr>
        </thead>
        <tbody>
          {roles.map((role) => (
            <tr key={role.id}>
              <td>{role.name}</td>
              <td>{role.description}</td>
              <td>
                <button>Edit</button> |{" "}
                <button>Delete</button>
              </td>
            </tr>
          ))}
        </tbody>
      </table>
    </div>
  );
}

3. Data Schema Example (Pydantic)

This schema defines the structure for roles and permissions.

from pydantic import BaseModel
from typing import List, Optional

class RoleCreate(BaseModel):
    name: str
    description: Optional[str] = None

class RoleResponse(BaseModel):
    id: str
    name: str
    description: Optional[str] = None
    permissions: List[str]

    class Config:
        orm_mode = True

Notes:

• The FastAPI endpoint demonstrates how to create a new role with validation using Pydantic models.
• The React component provides a simple UI for managing roles, including CRUD operations.
• The Pydantic schema defines the data structure for roles and permissions.

Technical Documentation: Role & Permission Editor Module

Module Name: Role & Permission Editor

Category: Security
Summary: Centralized platform for defining and managing user roles and permissions across the application.
Target User: Developers, System Administrators

Related Modules

1. Role Management: Manages creation, editing, and deletion of roles within the system.
