Allow custom Dtos for endpoints

MapInstantAPIs の構成エントリポイントから開始し、エンティティ型がエンドポイントのリクエストモデルになるまでを追跡します。要求された AddFoodDto/UseCustomDto の insert フローと、生成された Swagger の body を比較します。完了条件は、呼び出し元がエンドポイントにカスタム DTO を渡し、それが要求どおりエンティティにマッピングされることです。

Suppose I have this class

`
public class Food : Record
{

    public string Name { get; set; }
    public decimal Portion { get; set; }
    public decimal Calories { get; set; }
    public decimal Carbohydrates { get; set; }
    public decimal Lipids { get; set; }
    public decimal Proteins { get; set; }
    public decimal Fiber { get; set; }
    
    public Guid SourceId { get; set; }
    public Source Source { get; set; }

    public Classification Classification { get; set; }
    public NewClassification NewClassification { get; set; }

    public ICollection<FoodRecipes> FoodRecipes { get; set; }

}
`

When using InstantAPIs, the following swagger body model is created

{ "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6", "registration": "2023-09-04T02:26:10.760Z", "update": "2023-09-04T02:26:10.760Z", "deletion": "2023-09-04T02:26:10.760Z", "name": "string", "portion": 0, "calories": 0, "carbohydrates": 0, "lipids": 0, "proteins": 0, "fiber": 0, "sourceId": "3fa85f64-5717-4562-b3fc-2c963f66afa6", "source": { "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6", "registration": "2023-09-04T02:26:10.760Z", "update": "2023-09-04T02:26:10.760Z", "deletion": "2023-09-04T02:26:10.760Z", "name": "string" }, "classification": 0, "newClassification": 0, "foodRecipes": [ { "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6", "registration": "2023-09-04T02:26:10.760Z", "update": "2023-09-04T02:26:10.760Z", "deletion": "2023-09-04T02:26:10.760Z", "recipeId": "3fa85f64-5717-4562-b3fc-2c963f66afa6", "recipe": { "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6", "registration": "2023-09-04T02:26:10.760Z", "update": "2023-09-04T02:26:10.760Z", "deletion": "2023-09-04T02:26:10.760Z", "name": "string", "foodRecipes": [ "string" ] }, "foodId": "3fa85f64-5717-4562-b3fc-2c963f66afa6", "food": "string" } ] }

I wish there would be a way to provide custom DTOs and maybe using AutoMapper to transforming to entity class, like

app.MapInstantAPIs<EuNutroContext>(config => { config.ExcludeTable(db => db.AnyTable); config.UseCustomDto(db => db.Food, typeof(AddFoodDto), ApiMethodsToGenerate.Insert); // like this });
