## Ejemplo
|
|
|
|
```go
|
|
before := []map[string]any{
|
|
{"id": "1", "name": "Alice", "status": "active"},
|
|
{"id": "2", "name": "Bob"},
|
|
}
|
|
after := []map[string]any{
|
|
{"id": "1", "name": "Alice", "status": "inactive"},
|
|
{"id": "3", "name": "Carol"},
|
|
}
|
|
result := DiffEntities(before, after, "id", nil)
|
|
// result["summary"] = "1 added, 1 removed, 1 modified, 0 unchanged"
|
|
// result["added"] = [{"id": "3", "name": "Carol"}]
|
|
// result["removed"] = [{"id": "2", "name": "Bob"}]
|
|
// result["modified"] = [{"key": "1", "changes": {"status": {"old": "active", "new": "inactive"}}}]
|
|
```

## Notas
|
|
|
|
Funcion pura. Compara valores con fmt.Sprintf("%v", ...) para manejar tipos heterogeneos en map[string]any.
|
|
ignoreFields nil usa los defaults ["created_at", "updated_at"]. Para no ignorar ningun campo, pasar []string{}.
|
|
Semantica identica a diff_entities_py_datascience, permite comparar resultados entre ejecuciones del mismo pipeline.
