### 使用 Pydantic 的 `exclude_unset` 参数 { #using-pydantics-exclude-unset-parameter }

如果要接收部分更新，建议在 Pydantic 模型的 `.model_dump()` 中使用 `exclude_unset` 参数。

比如，`item.model_dump(exclude_unset=True)`。

这会生成一个 `dict`，只包含创建 `item` 模型时显式设置的数据，不包含默认值。

然后再用它生成一个只含已设置（在请求中发送）数据、且省略默认值的 `dict`：

{* ../../docs_src/body_updates/tutorial002_py310.py hl[32] *}

            .isEqualTo(hasEdge);
      }
    }
  }

  @Test
  public void directedGraph() {
    graph = ValueGraphBuilder.directed().allowsSelfLoops(true).build();
    graph.putEdgeValue(1, 2, "valueA");
    graph.putEdgeValue(2, 1, "valueB");
    graph.putEdgeValue(2, 3, "valueC");
    graph.putEdgeValue(4, 4, "valueD");

            builder.queryTime(searchResponse.getTook().millis());

            if (searchResponse.getTotalShards() != searchResponse.getSuccessfulShards()) {
                builder.partialResults(true);
            }

            // build highlighting fields
            final String hlPrefix = ComponentUtil.getQueryHelper().getHighlightPrefix();
            for (final SearchHit searchHit : searchHits.getHits()) {

    }

    @TaskAction
    public void runRat() {
        ReportConfiguration reportConfiguration = new ReportConfiguration();
        reportConfiguration.setAddingLicenses(true);
        List<IHeaderMatcher> matchers = new ArrayList<>();
        matchers.add(Defaults.createDefaultMatcher());

        // BSD 4-clause stuff (is disallowed below)

但本指南會大致示範它們各自的設計用法。

### 使用 Pydantic 的 `exclude_unset` 參數 { #using-pydantics-exclude-unset-parameter }

如果要接收部分更新，在 Pydantic 模型的 `.model_dump()` 中使用 `exclude_unset` 參數非常實用。

例如 `item.model_dump(exclude_unset=True)`。

這會產生一個只包含建立 `item` 模型時實際設定過之欄位的 `dict`，不含預設值。

接著你可以用它來生成只包含實際設定（請求中傳來）的資料之 `dict`，省略預設值：

{* ../../docs_src/body_updates/tutorial002_py310.py hl[32] *}

        item_id: str,
    ):
        if session is None:
            raise WebSocketException(code=status.WS_1008_POLICY_VIOLATION)
        await websocket.accept()
        while True:
            data = await websocket.receive_text()
            await websocket.send_text(f"Session cookie is: {session}")
            await websocket.send_text(f"Message text was: {data}, for item ID: {item_id}")
    ```
