What is the correct way to create api examples in NelmioApiDocBundle?

If you need to provide several options for incoming or outgoing data, how do you specify `examples’?

You can manually specify fields and their values, but
if I have a DTO model, shouldn’t I make a call to this model for an example?

In php, I tried to do it through a call, the example field accepts string, array, int but not the model.

I also tried using the factory, but you can’t call methods in php attributes.

There is an error

Compile Error: Constant expression contains invalid operations

The only thing that worked fine was the inheritance of OpenAPIAttributesExamples and in my class I made calls and it worked

Example my class (a handwritten example, but like this : ))

<?php  
  
namespace AppDto;  
  
use OpenApiAttributes as OA;  
use OpenApiAttributesExamples;  
use SymfonyComponentSerializerAnnotationGroups;  
  
class AggregatedProductDataSelectExample extends Examples  
{  
    public function __construct(  
        AggregatedProductDataSelect $model,  
        string $example,  
        string $summary,  
    ) {  
        $this->product = $product;  
        $this->is_forecast = $is_forecast;  
        $this->max_price = $max_price;  
  
        parent::__construct(  
            example: $example,  
            summary: $summary,  
            value: $model->toArray()  
        );  
    }  
}

Call

responses: [  
    new OAResponse(  
        response: 200,  
        description: 'Агрегированные данные по продуктам в периоде',  
        content: [  
            new OAJsonContent(  
                examples: [  
                    new AggregatedProductDataSelectExample(  
                        new AggregatedProductDataSelect(  
                            is_forecast: true,  
                            max_price: 1.0,  
                            product: '1',  
                        ),
                        summary: 'test1',
                        example: 'test ...'
                    ),  
                ],  
                properties: [  
                    new OAProperty(  
                        property: 'result',  
                        ref: new Model(type: AggregatedProductDataResponse::class, groups: ["default"])  
                    ),  
                ]  
            ),  
        ]  
    ),  
]

What is the right way to do this?
