!!! check
    So, with the same Python type declaration, **FastAPI** gives you data validation.

    Notice that the error also clearly states exactly the point where the validation didn't pass.

    This is incredibly helpful while developing and debugging code that interacts with your API.

## Documentation

# `Request` class

You can declare a parameter in a *path operation function* or dependency to be of type `Request` and then you can access the raw request object directly, without any validation, etc.

You can import it directly from `fastapi`:

```python
from fastapi import Request
```

!!! tip

# Body – Felder

So wie Sie zusätzliche Validation und Metadaten in Parametern der **Pfadoperation-Funktion** mittels `Query`, `Path` und `Body` deklarieren, können Sie auch innerhalb von Pydantic-Modellen zusätzliche Validation und Metadaten deklarieren, mittels Pydantics `Field`.

## `Field` importieren

Importieren Sie es zuerst:

=== "Python 3.10+"

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001_an_py310.py!}
    ```

dependencies {
    implementation(enforcedPlatform("org.junit:junit-bom:5.7.1"))
}

// tag::disable_validation[]
tasks.withType<GenerateModuleMetadata> {
    // The value 'enforced-platform' is provided in the validation
    // error message you got
    suppressedValidationErrors.add("enforced-platform")
}

                .add(pluginJar)
        } else {
            Logging.getLogger(javaClass).warn("Validation won't be performed for plugin '{}' because we couldn't locate its jar file", pluginId)
        }
    }
}

dependencies {
    implementation enforcedPlatform('org.junit:junit-bom:5.7.1')
}

// tag::disable_validation[]
tasks.withType(GenerateModuleMetadata).configureEach {
    // The value 'enforced-platform' is provided in the validation
    // error message you got
    suppressedValidationErrors.add('enforced-platform')
}

    }
}
```

Again, doing just that declaration, with **FastAPI** you get:

* Editor support (completion, etc.), even for nested models
* Data conversion
* Data validation
* Automatic documentation

## Special types and validation

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.

// RUN: tf-opt -verify-clustering-pass  -split-input-file -verify-diagnostics %s | FileCheck %s
// Tests the VerifyClusteringPass Pass, ensures that an error is thrown when validation fails.

func.func @testNotTfDialect(%arg0: tensor<1x32x10x32xi32>, %arg1: tensor<32xi32>) -> tensor<1x32x10x32xi32> {
 // expected-error@below {{op is in dialect chlo not in tf functional dialect}}

stdout.
Otherwise they're just normal programs.

## Trace debug commands

The `cmd` directory contains helpful tools for debugging traces.

* `gotraceraw` parses traces without validation.
  It can produce a text version of the trace wire format, or convert
  the text format back into bytes.
* `gotracevalidate` parses traces and validates them.
  It performs more rigorous checks than the parser does on its own,
