func NewEntityManagerWithConfig ¶

func NewEntityManagerWithConfig(config *forma.Config, pool *pgxpool.Pool) (forma.EntityManager, error)

NewEntityManagerWithConfig creates a new EntityManager with the provided configuration and database pool. This is the primary way for external projects to create an EntityManager instance.

If config.SchemaRegistry is provided, it will be used instead of creating a file-based registry. This allows callers to provide their own SchemaRegistry implementation.

Usage:

import (

"github.com/lychee-technology/forma"
"github.com/lychee-technology/forma/factory"

)

config := forma.DefaultConfig(registry) em, err := factory.NewEntityManagerWithConfig(config, pool)

if err != nil {
   // handle error
}

With custom SchemaRegistry:

config := forma.DefaultConfig(registry) config.SchemaRegistry = myCustomRegistry em, err := factory.NewEntityManagerWithConfig(config, pool)

func NewEntityManagerWithConfigContext ¶ added in v0.0.25

func NewEntityManagerWithConfigContext(ctx context.Context, config *forma.Config, pool *pgxpool.Pool) (forma.EntityManager, error)

NewEntityManagerWithConfigContext creates a new EntityManager using the provided context, configuration, and database pool. It is the canonical implementation; use this when you need to control the context used during initialisation (e.g. to propagate cancellation or deadlines to the startup queries).

See NewEntityManagerWithConfig for usage examples.

func NewFileSchemaRegistry ¶ added in v0.0.15

func NewFileSchemaRegistry(pool *pgxpool.Pool, schemaTable string, schemaDir string) (forma.SchemaRegistry, error)
