How does this skill handle thread safety in Go?

The skill implements internal mutexes within model fields, making all .Get() and .Set() operations safe for concurrent access from multiple goroutines.

What is the difference between .Get() and .GetI() for structs?

.Get() returns both the value and an error for safety, while .GetI() returns only the value, which is useful when error checking is not required by the logic.

How are nullable fields handled?

Fields with null constraints include specific methods like .SetNull() to clear values and .IsNull() to check the field's current state.

Can I use this with JSONB database columns?

Yes, it provides a specialized StructField[T] type that allows you to set and retrieve complex Go structs from JSONB columns with built-in error handling.

Manages thread-safe model field access and instantiation using standardized Go patterns.

소개

This skill provides a comprehensive guide and implementation pattern for interacting with database models in Go. It enforces thread-safe field access through standardized .Get() and .Set() methods, ensuring data integrity during concurrent operations. It covers various scenarios including typed constructors for joined models, specialized handling for JSONB struct fields, and specific methods for nullable columns, allowing Claude to write consistent, high-quality backend code that follows established repository conventions.
