Using sea-orm entities with poem-openapi

[zchira]

Simple question:
Let's say we have database with few tables. Let's use generic example for tables: Author and Posts (one-to-many relation).
With sea-orm-cli we can generate entities structs AuthorEntity and PostEntity.

On the other side, I have poem-openapi endpoints:
GET /authors - return all authors
GET /authors/:authorId/posts - return all posts from author identified with authorId

What would be the cleanest way to do that?
I guess, from the endpoint I can't directly return structs AuthorEntity and PostEntity since they don't have #derive(Object)?
The other way would be to create my own structs:

#derive(Object) 
struct Author {
...
}

#derive(Object) 
struct Post {
...
}

and to implement From trait for AuthorEntity and PostEntity for them:

impl From<AuthorEntity> for Author {
...
}

impl From<PostEntity> for Post {
...
}

Is there some more elegant/clean/rusty way?

I am not familiar with sea-orm but what about just adding the Object derive to the AuthorEntity?

You can even do this on generation with --model-extra-derives

Thanks @chikko80 ,
that makes sense.

I tried to add --model-extra-derives Object and the generated entity has:
#[derive(Clone, Debug, PartialEq, DeriveEntityModel, Eq, Object)]

But, since there is no use poem_openapi_derive::Object compile error is thrown.

I tried also with:
--model-extra-derives poem_openapi_derive::Object
but the generated entity looks bad:
#[derive(Clone, Debug, PartialEq, DeriveEntityModel, Eq, poem_openapi :: Object)] (<< spaces before and afte ::).

I'll check the docs for sea-orm-cli to see if there are some other options 👍

Otherwise reach out to the seaorm devs / open a question/issue.
I've heard the team is quit responsive and always happy to get suggestions for improvements

@zchira

would you mind pinging me here if you have a solution for this?
I am planning to try out seaorm in an upcoming project and would face the same issue

[zchira]

Sure, I asked on sea-orm discussions also ( link )
