[oapi] salvo::prelude::ToSchema is not implemented for JsonValue

[josejachuf]

Continuing with the migration of the app from the documentation using utoipa bookstore by hand to the integration of oapi in salvo.

I have the struct

#[derive(FromRow, Serialize, ToSchema, Debug)]
pub struct MyStruct {
    ...
    ...
    pub my_field: Option<serde_json::Value>,    
}

12 | #[derive(FromRow, Serialize, ToSchema, Debug)]
   |                              ^^^^^^^^ the trait `salvo::prelude::ToSchema` is not implemented for `JsonValue`
   

Actually my field must be of type Option<Vec>, but sqlx gives me a mistake. That's another topic that I'm going to see in sqlx.

Summarizing, using utoipa with:

#[derive(FromRow, Serialize, ToSchema, Debug)]
pub struct MyStruct {
    ...
    ...
    pub my_field: Option<serde_json::Value>,    
}

works fine, but with the one integrated in Salvo, it gives the aforementioned error

Try this:

#[derive(FromRow, Serialize, ToSchema, Debug)]
pub struct MyStruct {
    ...
    ...
    #[salvo(schema(value_type = Option<Object>))]
    pub my_field: Option<serde_json::Value>,    
}

Apparently this works fine. I'm going to see it in more detail
Thanks
