HTML Feedback Support in Teacher Evaluation API

🎨 Rich Text Support

YES! Your API fully supports HTML-formatted feedback content, just like what CKEditor produces. The feedback_content field accepts and preserves all HTML formatting.

✅ What HTML Features Are Supported

Your system supports all standard HTML elements including:

Headings: <h1>, <h2>, <h3>, etc.
Text Formatting: <strong>, <em>, <u>, <span>
Lists: <ul>, <ol>, <li>
Tables: <table>, <tr>, <td>, <th>
Paragraphs: <p>, <div>, <blockquote>
Styling: style attributes for colors, fonts, spacing
Links: <a href="..."> (preserved as-is)
Images: <img src="..."> (URLs preserved)

📝 CKEditor Integration

Your CKEditor already produces HTML that works perfectly with the API:

CKEditor Output → API Input

// What CKEditor gives you
const editorContent = editor.getData();
// Returns: "<h3>Feedback</h3><p>Student shows <strong>excellent</strong> work...</p>"

// Send directly to API
const feedbackData = {
    "title": "Assignment Feedback",
    "feedback_content": editorContent,  // HTML content as-is
    "teacher_name": "Dr. Smith",
    "assessment_type": "essay",
    // ... other fields
};

🚀 API Examples with HTML Content

🔧 Integration Examples

Frontend JavaScript (sending CKEditor content)

// Get content from CKEditor
const feedbackHTML = CKEDITOR.instances.feedback_editor.getData();

// Prepare API payload
const apiPayload = {
    organization_id: selectedOrgId,
    feedbacks: [{
        title: document.getElementById('feedback_title').value,
        feedback_content: feedbackHTML,  // Rich HTML content
        teacher_name: document.getElementById('teacher_name').value,
        teacher_experience_level: document.getElementById('experience').value,
        assessment_type: document.getElementById('assessment_type').value,
        student_level: document.getElementById('student_level').value,
        subject_area: document.getElementById('subject_area').value
    }]
};

// Send to API
fetch('/assessment/api/feedbacks/bulk/', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${authToken}`
    },
    body: JSON.stringify(apiPayload)
})
.then(response => response.json())
.then(data => {
    console.log('Feedback submitted:', data);
});

Python Integration

import requests
from bs4 import BeautifulSoup

def submit_html_feedback(auth_token, org_id, html_feedback_data):
    """Submit HTML feedback via API"""

    url = "http://Preparebuddy.com/assessment/api/feedbacks/bulk/"
    headers = {
        "Authorization": f"Bearer {auth_token}",
        "Content-Type": "application/json"
    }

    # Prepare payload with HTML content
    payload = {
        "organization_id": org_id,
        "feedbacks": [{
            "title": html_feedback_data['title'],
            "feedback_content": html_feedback_data['html_content'],  # HTML as-is
            "teacher_name": html_feedback_data['teacher'],
            "assessment_type": "essay",
            "student_level": "Undergraduate",
            "subject_area": html_feedback_data['subject']
        }]
    }

    response = requests.post(url, json=payload, headers=headers)

    if response.status_code == 201:
        return response.json()
    else:
        raise Exception(f"API Error: {response.status_code} - {response.text}")

# Example usage
html_content = """
<h2>Assignment Evaluation</h2>
<p>The student shows <strong>excellent progress</strong> in understanding the material.</p>
<h3>Key Strengths:</h3>
<ul>
    <li>Clear analytical thinking</li>
    <li>Good use of examples</li>
    <li>Well-organized presentation</li>
</ul>
<p style="color: #2E8B57;"><strong>Grade: A- (92%)</strong></p>
"""

feedback_data = {
    'title': 'Weekly Assignment Review',
    'html_content': html_content,
    'teacher': 'Prof. Smith',
    'subject': 'Computer Science'
}

result = submit_html_feedback(auth_token, org_id, feedback_data)
print(f"Submitted feedback ID: {result['feedbacks'][0]['id']}")

📊 Word Count Calculation

The API automatically calculates word count from HTML content by:

Extracting text: Strips HTML tags to get plain text
Counting words: Splits by whitespace and counts
Storing both: Preserves original HTML + calculates word count

# Example: This HTML content
html_content = "<h3>Great work!</h3><p>The student shows <strong>excellent</strong> understanding.</p>"

# Becomes word count: 8
# (Great, work, The, student, shows, excellent, understanding)

🎯 Best Practices for HTML Feedback

1. Structure Your Feedback

<h3>Overall Assessment</h3>
<p>Brief summary...</p>

<h4>Strengths</h4>
<ul>
    <li>Point 1</li>
    <li>Point 2</li>
</ul>

<h4>Areas for Improvement</h4>
<ol>
    <li>Improvement 1</li>
    <li>Improvement 2</li>
</ol>

<h4>Grade</h4>
<p><strong>Final Score: A- (92%)</strong></p>

2. Use Semantic HTML

<!-- Good: Semantic elements -->
<h3>Assessment Results</h3>
<p><strong>Excellent work</strong> on this assignment.</p>
<blockquote>This demonstrates deep understanding.</blockquote>

<!-- Avoid: Presentation-only markup -->
<font color="red" size="5">Assessment Results</font>
<b>Excellent work</b> on this assignment.

3. Include Visual Elements

<!-- Tables for structured feedback -->
<table border="1" style="border-collapse: collapse;">
    <tr>
        <th>Criteria</th>
        <th>Score</th>
        <th>Comments</th>
    </tr>
    <tr>
        <td>Content Quality</td>
        <td>85%</td>
        <td>Well researched and organized</td>
    </tr>
</table>

<!-- Colored text for emphasis -->
<p style="color: #2E8B57;"><strong>Excellent work!</strong></p>
<p style="color: #CD853F;"><em>Needs improvement</em></p>

🔄 Processing Flow

Here's how HTML feedback flows through your system:

CKEditor → HTML Content → API Submission → Database Storage → AI Evaluation → Report Generation
    ↓              ↓              ↓              ↓              ↓              ↓
Rich Text   →  HTML String  →  JSON Payload  →  TextField   →  AI Analysis  →  Formatted Report

CKEditor produces rich HTML
API receives and validates HTML
Database stores HTML exactly as received
AI Evaluation analyzes the HTML content
Reports can render HTML or convert to plain text

🛡️ HTML Safety and Validation

Your system handles HTML safely:

Storage: HTML is stored exactly as received
Display: HTML can be rendered safely in reports
Analysis: AI models process both HTML structure and text content
Word Count: Automatically extracted from HTML

Optional: HTML Sanitization

If you want to restrict certain HTML elements:

from bs4 import BeautifulSoup

def sanitize_feedback_html(html_content):
    """Optional: Clean HTML if needed"""
    soup = BeautifulSoup(html_content, 'html.parser')

    # Remove potentially problematic elements
    for script in soup(["script", "style"]):
        script.decompose()

    # Keep only safe tags
    allowed_tags = ['h1', 'h2', 'h3', 'h4', 'h5', 'h6', 'p', 'br', 'strong', 
                   'em', 'u', 'ul', 'ol', 'li', 'table', 'tr', 'td', 'th', 
                   'blockquote', 'span', 'div', 'a']

    return str(soup)

📈 Advanced Features

Embedded Images

<!-- Images are preserved with their URLs -->
<p>Student's diagram analysis:</p>
<img src="/media/uploads/student_diagram.png" alt="Student diagram" style="max-width: 500px;">
<p>The diagram shows good understanding of the concept.</p>

Styled Tables for Rubric Feedback

<table style="width: 100%; border-collapse: collapse; margin: 15px 0;">
    <tr style="background-color: #f8f9fa;">
        <th style="border: 1px solid #dee2e6; padding: 12px;">Criteria</th>
        <th style="border: 1px solid #dee2e6; padding: 12px;">Weight</th>
        <th style="border: 1px solid #dee2e6; padding: 12px;">Score</th>
        <th style="border: 1px solid #dee2e6; padding: 12px;">Comments</th>
    </tr>
    <tr>
        <td style="border: 1px solid #dee2e6; padding: 12px;">Content Quality</td>
        <td style="border: 1px solid #dee2e6; padding: 12px;">40%</td>
        <td style="border: 1px solid #dee2e6; padding: 12px;">85%</td>
        <td style="border: 1px solid #dee2e6; padding: 12px;">Excellent research and analysis</td>
    </tr>
</table>
