Functions ¶
func Database ¶
Database creates and returns a generic database manipulator implementing types.Database interface. Provides comprehensive CRUD capabilities with advanced features like caching, hooks, and query building. Automatically enables debug mode when log level is set to debug.
Type Parameters:
- M: Model type that implements types.Model interface
Parameters:
- ctx: Required database context for request tracing and metadata. In service layer operations, pass a valid DatabaseContext to track requests. For non-service layer operations, pass nil.
Returns a database manipulator with full CRUD and query capabilities.
Features:
- Generic type safety for model operations
- Automatic debug mode based on configuration
- Context-aware operations for tracing
- Default query limit protection
- Panic protection for uninitialized database
Example:
// Service layer usage with context
db := Database[*User](ctx.DatabaseContext())
// Non-service layer usage
db := Database[*User](nil)
users := db.WithQuery(&User{Name: "John"}).List()
