但接著我們在路徑操作函式（*path operation function*）的參數 `commons` 中取得的是一個 `dict`。

而我們知道，編輯器對 `dict` 無法提供太多輔助（例如自動完成），因為它無法預先知道其中的鍵與值的型別。

我們可以做得更好...

## 什麼算是相依性 { #what-makes-a-dependency }

到目前為止，你看到的相依性都是宣告成函式。

但那不是宣告相依性的唯一方式（雖然那大概是最常見的）。

關鍵在於，相依性應該要是「callable」。

在 Python 中，「**callable**」指的是任何可以像函式一樣被 Python「呼叫」的東西。

因此，如果你有一個物件 `something`（它可能不是函式），而你可以像這樣「呼叫」（執行）它：

import org.junit.jupiter.api.Test

class ConnectionPoolTest {
  private val routePlanner = FakeRoutePlanner()
  private val factory = routePlanner.factory
  private val peer = MockHttp2Peer()

  /** The fake task runner prevents the cleanup runnable from being started.  */
  private val addressA = factory.newAddress("a")
  private val routeA1 = factory.newRoute(addressA)
  private val addressB = factory.newAddress("b")

			return
		}
		if sameTarget && bucket == clnt.Bucket {
			writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrBucketRemoteIdenticalToSource), r.URL)
			return
		}

		reader := bytes.NewReader(buf)
		// fake a PutObject and RemoveObject call to validate permissions
		c := &minio.Core{Client: clnt.Client}
		putOpts := minio.PutObjectOptions{
			Internal: minio.AdvancedPutOptions{
				SourceVersionID:          mustGetUUID(),

    /**
     * Determines whether this resource represents a workgroup reference.
     *
     * @return whether this is a workgroup reference
     * @throws CIFSException if the determination cannot be made
     */
    boolean isWorkgroup() throws CIFSException;

    /**
     * Determines whether this resource represents the root of the SMB hierarchy.
     *
     * @return whether this is a root resource

И мы знаем, что редакторы кода не могут обеспечить достаточную поддержку (например, автозавершение) для `dict`, поскольку они не могут знать их ключи и типы значений.

Мы можем сделать лучше...

## Что делает зависимость { #what-makes-a-dependency }

До сих пор вы видели зависимости, объявленные как функции.

Но это не единственный способ объявления зависимостей (хотя он, вероятно, более распространенный).

The same models are shared among requests, so, it's not one model per request, or one per user or something similar.

Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.
