然后再用它生成一个只含已设置（在请求中所发送）数据，且省略了默认值的 `dict`：

```Python hl_lines="34"
{!../../../docs_src/body_updates/tutorial002.py!}
```

### 使用 Pydantic 的 `update` 参数

接下来，用 `.copy()` 为已有模型创建调用 `update` 参数的副本，该参数为包含更新数据的 `dict`。

例如，`stored_item_model.copy(update=update_data)`：

```Python hl_lines="35"
{!../../../docs_src/body_updates/tutorial002.py!}
```

### 更新部分数据小结

简而言之，更新部分数据应：

Wie in `stored_item_model.model_copy(update=update_data)`:

=== "Python 3.10+"

    ```Python hl_lines="33"
    {!> ../../../docs_src/body_updates/tutorial002_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="35"
    {!> ../../../docs_src/body_updates/tutorial002_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="35"
    {!> ../../../docs_src/body_updates/tutorial002.py!}
    ```

    {!> ../../../docs_src/body_updates/tutorial002_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="35"
    {!> ../../../docs_src/body_updates/tutorial002_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="35"
    {!> ../../../docs_src/body_updates/tutorial002.py!}
    ```

### Partial updates recap

In summary, to apply partial updates you would:

    ```Python hl_lines="34"
    {!> ../../../docs_src/body_updates/tutorial002.py!}
    ```

=== "🐍 3️⃣.9️⃣ & 🔛"

    ```Python hl_lines="34"
    {!> ../../../docs_src/body_updates/tutorial002_py39.py!}
    ```

=== "🐍 3️⃣.1️⃣0️⃣ & 🔛"

    ```Python hl_lines="32"
    {!> ../../../docs_src/body_updates/tutorial002_py310.py!}
    ```

### ⚙️ Pydantic `update` 🔢

```Python hl_lines="34"
{!../../../docs_src/body_updates/tutorial002.py!}
```

### Pydanticの`update`パラメータ

ここで、`.copy()`を用いて既存のモデルのコピーを作成し、`update`パラメータに更新するデータを含む`dict`を渡すことができます。

`stored_item_model.copy(update=update_data)`のように:

```Python hl_lines="35"
{!../../../docs_src/body_updates/tutorial002.py!}
```

### 部分的更新のまとめ

まとめると、部分的な更新を適用するには、次のようにします:

# Configures Depdendabot to PR go security updates only

version: 2
updates:
  # Go configuration for master branch
  - package-ecosystem: "gomod"
    directory: "/"
    schedule:
      interval: "daily"
    # Limit number of open PRs to 0 so that we only get security updates
    # See https://docs.github.com/en/code-security/dependabot/dependabot-security-updates/configuring-dependabot-security-updates

        String checksums = toRepositoryChecksumPolicy(RepositoryPolicy.CHECKSUM_POLICY_WARN); // the default
        String updates = RepositoryPolicy.UPDATE_POLICY_DAILY;

        if (policy != null) {
            enabled = policy.isEnabled();
            if (policy.getUpdatePolicy() != null) {
                updates = policy.getUpdatePolicy();
            }
            if (policy.getChecksumPolicy() != null) {

					}
				}
				// Collect updates.
				updates := make(chan dataUsageEntry, 1)
				var wg sync.WaitGroup
				wg.Add(1)
				go func(name string) {
					defer wg.Done()
					for update := range updates {
						select {
						case <-ctx.Done():
						case bucketResults <- dataUsageEntryInfo{
							Name:   name,
							Parent: dataUsageRoot,
							Entry:  update,
						}:
						}
					}

		return err
	}
	for {
		// listen for updates:
		select {
		case update, ok := <-conn.Updates:
			if !ok {
				log.Debug("update channel closed - returning")
				return nil
			}
			log.Debugf("got update to send to ztunnel")
			resp, err := conn.sendDataAndWaitForAck(update.Update, update.Fd)
			if err != nil {

	default:
		m = cache.iamUsersMap
	}
	err := store.loadUser(ctx, accessKey, userType, m)

	if err == errNoSuchUser {
		// User was deleted - we update the cache.
		delete(m, accessKey)

		// Since cache was updated, we update the timestamp.
		defer func() {
			cache.updatedAt = time.Now()
		}()

		// 1. Start with updating user-group memberships
