## Query-Parameter-Liste / Mehrere Werte { #query-parameter-list-multiple-values }

Wenn Sie einen Query-Parameter explizit mit `Query` definieren, können Sie ihn auch so deklarieren, dass er eine Liste von Werten empfängt, oder anders gesagt, dass er mehrere Werte empfangen kann.

## Die App mit mehreren Modellen aktualisieren { #update-the-app-with-multiple-models }

Jetzt lassen Sie uns diese App ein wenig **refaktorisieren**, um die **Sicherheit** und **Vielseitigkeit** zu erhöhen.

Но во многих случаях вы захотите одновременно запустить несколько процессов‑воркеров.

## Lista de parâmetros de consulta / múltiplos valores { #query-parameter-list-multiple-values }

Quando você define explicitamente um parâmetro de consulta com `Query`, você também pode declará-lo para receber uma lista de valores, ou seja, receber múltiplos valores.
