Comment System Architecture Fix

Required Code Modifications

1. Central CommentThread Model (comments/models.py)

from django.contrib.contenttypes.fields import GenericForeignKey, GenericRelation
from django.contrib.contenttypes.models import ContentType
from django.db import models

class CommentThread(models.Model):
    """Centralized comment threading system"""
    content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
    object_id = models.PositiveIntegerField()
    content_object = GenericForeignKey()
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        indexes = [
            models.Index(fields=["content_type", "object_id"]),
        ]
        app_label = 'comments'

2. Model Reference Updates (Example for companies/models.py)

# In all affected models (companies, rides, parks, reviews):
from comments.models import CommentThread

class Company(models.Model):
    # ... existing fields ...
    comments = GenericRelation(CommentThread)  # Updated reference

3. Historical Records Adjustment

# Historical model definitions:
class HistoricalCompany(HistoricalRecords):
    comments = models.ForeignKey(
        'comments.CommentThread',  # Unified reference
        on_delete=models.SET_NULL,
        null=True,
        blank=True
    )

Migration Execution Plan

1. Generate initial comment thread migration:

./manage.py makemigrations comments --name create_commentthread

2. Create dependent migrations for each modified app:

for app in companies rides parks reviews; do
    ./manage.py makemigrations $app --name update_comment_references
done

3. Migration dependency chain:

# In each app's migration file:
dependencies = [
    ('comments', '0001_create_commentthread'),
]

Validation Checklist

• Run full test suite: uv test ./manage.py test
• Execute system check: uv run ./manage.py check --deploy
• Verify database schema changes in migration files
• Confirm admin interface comment relationships
