### Using Pydantic's `exclude_unset` parameter { #using-pydantics-exclude-unset-parameter }

If you want to receive partial updates, it's very useful to use the parameter `exclude_unset` in Pydantic's model's `.model_dump()`.

Like `item.model_dump(exclude_unset=True)`.

/// info

In Pydantic v1 the method was called `.dict()`, it was deprecated (but still supported) in Pydantic v2, and renamed to `.model_dump()`.

      // If the path is absent or didn't start with '/', use the default path. It's a string like
      // '/foo/bar' for a URL like 'http://example.com/foo/bar/baz'. It always starts with '/'.
      if (path == null || !path.startsWith("/")) {
        val encodedPath = url.encodedPath
        val lastSlash = encodedPath.lastIndexOf('/')

    Configure basic logging like this:

    ```java
    HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
    loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BASIC);
    client.networkInterceptors().add(loggingInterceptor);

# `Response` class

You can declare a parameter in a *path operation function* or dependency to be of type `Response` and then you can set data for the response like headers or cookies.

You can also use it directly to create an instance of it and return it from your *path operations*.

You can import it directly from `fastapi`:

```python
from fastapi import Response
```
