Multi-Category Relationship Guide

System Update: Many-to-Many Relationships

The platform has been upgraded from a simple one-to-many relationship to a robust Many-to-Many system for Categories and Guides.

Key Changes

• Old System: One guide could only belong to one category.
• New System: One guide can now be assigned to multiple categories (e.g., a guide can be both "DevOps" and "Security").

Managing Categories

When editing a guide in the Admin Panel, you will now see a multi-select interface.

1. Click on category tags to toggle them.
2. Selected categories will be highlighted in green.
3. The changes are saved automatically when you submit the form.

Technical Detail

This is implemented using a join table _CategoryToGuide which ensures data integrity across all relationships.
