gorm-polymorphism

What problem does it solve?

Many applications need a child model to belong to different parent models, but traditional foreign keys require separate columns per parent type, causing schema bloat and inflexible queries. This skill provides a unified way to model such relationships in GORM.

Core Features & Use Cases

• Unified Owner Columns: Stores both owner ID and owner type in a single table, reducing schema complexity.
• Has‑One and Has‑Many Support: Works for singular and collection associations, e.g., a comment belonging to posts or videos.
• Custom Column Names: Allows overriding default column names and type values for legacy schemas.
• Eager Loading & Association Mode: Preload polymorphic data and manage relationships with GORM’s association API.
• Practical Scenarios: Comment systems, taggable items, address books, and activity feeds where multiple entity types share a common child model.
