#### 別のモデルの内容からつくるPydanticモデル { #a-pydantic-model-from-the-contents-of-another }

上述の例では`user_in.model_dump()`から`user_dict`をこのコードのように取得していますが:

```Python
user_dict = user_in.model_dump()
UserInDB(**user_dict)
```

これは以下と同等です:

```Python

import java.util.Set;
import org.jspecify.annotations.Nullable;

/**
 * A collection that maps keys to values, similar to {@link Map}, but in which each key may be
 * associated with <i>multiple</i> values. You can visualize the contents of a multimap either as a
 * map from keys to <i>nonempty</i> collections of values:
 *
 * <ul>
 *   <li>a → 1, 2
 *   <li>b → 3
 * </ul>
 *
 * ... or as a single "flattened" collection of key-value pairs:
 *

func (fi FileInfo) IsCompressed() bool {
	_, ok := fi.Metadata[ReservedMetadataPrefix+"compression"]
	return ok
}

// InlineData returns true if object contents are inlined alongside its metadata.
func (fi FileInfo) InlineData() bool {
	_, ok := fi.Metadata[ReservedMetadataPrefixLower+"inline-data"]
	// Earlier MinIO versions didn't reset "x-minio-internal-inline-data"

		s.err = err
	}
}

// Buffer controls memory allocation by the Scanner.
// It sets the initial buffer to use when scanning
// and the maximum size of buffer that may be allocated during scanning.
// The contents of the buffer are ignored.
//
// The maximum token size must be less than the larger of max and cap(buf).
// If max <= cap(buf), [Scanner.Scan] will use this buffer only and do no allocation.
//

			}
			// We use a single recursive 'adb push' of the module root instead of
			// walking the tree and copying it piecewise. If the directory tree
			// contains nested modules this could push a lot of unnecessary contents,
			// but for the golang.org/x repos it seems to be significantly (~2x)
			// faster than copying one file at a time (via filepath.WalkDir),
			// apparently due to high latency in 'adb' commands.
