Overview ¶

Package morphmap holds the process-wide registry of polymorphic aliases shared by the orm and gorm packages. It mirrors fedaco's static Relation._morphMap (libs/fedaco/src/fedaco/ relations/relation.ts:31) while remaining safe for concurrent reads from many query goroutines.

Most app code interacts with the registry via the wrappers in package orm (orm.MorphMap, orm.MorphedModel, orm.MorphAlias). The lower-level gorm wrapper imports this package directly to resolve morph values during query construction without introducing a circular dependency on package orm.

Functions ¶

func AliasOf ¶

func AliasOf(model any) (string, bool)

AliasOf returns the alias registered for the given model's underlying type.

func All ¶

func All() map[string]reflect.Type

All returns a snapshot copy of the alias-to-type registry.

func Find ¶

func Find(alias string) any

Find returns a fresh pointer to a new instance of the model registered under alias, or nil if no model is registered.

func MorphValue ¶

func MorphValue(model any) (string, bool)

MorphValue resolves the morph alias for a model. Resolution order:

model.MorphClass() if the model (or its pointer) implements ModelWithMorphClass
global morph map (registered via Register)

Returns "" and false if neither resolves. The caller is then expected to fall back to GORM's `polymorphicValue:` tag or the parent's table name.

func Register ¶

func Register(entries map[string]any, merge ...bool)

Register stores a set of alias-to-sample-model bindings. Subsequent calls merge with previously registered entries; later writes win on conflict. Pass false in the optional merge argument to replace the registry instead of merging.

func Reset ¶

func Reset()

Reset clears all entries. Intended for tests.
