Import `ServerSentEvent` from `fastapi.sse`:

{* ../../docs_src/server_sent_events/tutorial002_py310.py hl[4,26] *}

The `data` field is always encoded as JSON. You can pass any value that can be serialized as JSON, including Pydantic models.

## Raw Data { #raw-data }

If you need to send data **without** JSON encoding, use `raw_data` instead of `data`.

    <property name="id" value="SnippetLength" />
    <property name="max" value="76" />
  </module>

  <!-- Its our official line length! See checkstyle_suppressions.xml for the files that don't pass this. For now we
    suppress the check there but enforce it everywhere else. This prevents the list from getting longer even if it is
    unfair. -->
  <module name="LineLength">
    <property name="max" value="140" />

### Using Pydantic's `update` parameter { #using-pydantics-update-parameter }

Now, you can create a copy of the existing model using `.model_copy()`, and pass the `update` parameter with a `dict` containing the data to update.

Like `stored_item_model.model_copy(update=update_data)`:

{* ../../docs_src/body_updates/tutorial002_py310.py hl[33] *}

		if err != nil && !test.shouldFail {
			t.Errorf("Test %d: test should pass but it failed: %v", i, err)
		}

		decoded := encoded
		if !test.shouldFail {
			if test.reconstructParity {
				for j := range decoded {
					if decoded[j] == nil {
