### Usando o parâmetro `update` do Pydantic

Agora, você pode criar uma cópia do modelo existente usando `.model_copy()`, e passar o parâmetro `update` com um `dict` contendo os dados para atualizar.

/// info | Informação

	ctx := r.Context()

	addOrUpdateIDPHandler(ctx, w, r, false)
}

// UpdateIdentityProviderCfg: updates an existing IDP config for openid/ldap.
//
// POST <admin-prefix>/idp-cfg/openid/dex1 -> update named config `dex1`
//
// POST <admin-prefix>/idp-cfg/openid/_ -> update (default) named config `_`
func (a adminAPIHandlers) UpdateIdentityProviderCfg(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()

	}

	if err := DB.Model(&data).Update("password", EncryptedData("xnewpass")).Error; err == nil {
		t.Errorf("Should failed to update data with invalid data")
	}

	if err := DB.Model(&data).Update("password", EncryptedData("newpass")).Error; err != nil {
		t.Errorf("Should got no error update data with valid data, but got %v", err)
	}

				return nil
			}
		}
		opts := updateServiceAccountOpts{
			secretKey:     change.Update.SecretKey,
			status:        change.Update.Status,
			name:          change.Update.Name,
			description:   change.Update.Description,
			sessionPolicy: sp,
			expiration:    change.Update.Expiration,
		}

		{
			[]clause.Interface{
				clause.Update{},
				clause.Set([]clause.Assignment{{clause.PrimaryColumn, 1}}),
			},
			"UPDATE `users` SET `users`.`id`=?",
			[]interface{}{1},
		},
		{
			[]clause.Interface{
				clause.Update{},
				clause.Set([]clause.Assignment{{clause.PrimaryColumn, 1}}),
				clause.Set([]clause.Assignment{{clause.Column{Name: "name"}, "jinzhu"}}),
			},
			"UPDATE `users` SET `name`=?",

これを使うことで、デフォルト値を省略して、設定された（リクエストで送られた）データのみを含む`dict`を生成することができます:

```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:

        indexingHelper.deleteDocumentsByDocId(client, docList);
        assertEquals("fess.update", resultMap.get("index"));
        assertEquals(0, ((List<String>) resultMap.get("ids")).size());

        docList.add("001");
        indexingHelper.deleteDocumentsByDocId(client, docList);
        assertEquals("fess.update", resultMap.get("index"));
        assertEquals(1, ((List<String>) resultMap.get("ids")).size());

 *  **Request cancellation fixes.** This update fixes a bug where synchronous
    requests couldn't be canceled by tag. This update avoids crashing when
    `onResponse()` throws an `IOException`. That failure will now be logged
    instead of notifying the thread's uncaught exception handler. We've added a
    new API, `Call.isCanceled()` to check if a call has been canceled.

 *  New: Update `MultipartBuilder` to support content length.

	AssertEqual(t, result4, namedUser)

	if err := DB.Exec("UPDATE named_users SET name1 = @name, name2 = @name2, name3 = @name", sql.Named("name", "jinzhu-new"), sql.Named("name2", "jinzhu-new2")).Error; err != nil {
		t.Errorf("failed to update with named arg")
	}

	namedUser.Name1 = "jinzhu-new"
	namedUser.Name2 = "jinzhu-new2"
