Generating examples for abstract request type

[michaeljon]

I have a controller that take an abstract base class as the input. I'm using JsonDerivedType to tell System.Text.Json how to turn the inbound data into a concrete type. I'd like to provide examples for the various types but am running into an issue where the IMultipleExamplesProvider has to take the abstract type and then when the example is serialized the type information is lost from the more concrete type. This loses the $type discriminator in the examples. I really don't want to write these as XML examples - the magic strings are going to get way out of date.

Is there something I'm missing? I've tried type-specific examples but can only use on SwaggerRequestExample per method and the last one wins.

Hello

I've never used IMultipleExamplesProvider myself. According to my changelog, they were contributed by @tomkludy and @pozy.

Sorry for the delay in responding - I thought I would have time to have a play myself and see if I could figure it out, but I haven't had a chance to play yet, and I can't make any promises.

Hi,
Can you provide your implementation of IMultipleExamplesProvider which you have problem with? And screenshot how it looks in Swagger?
I don't remember much of this code, but will try to check what's going on.

I have the same issue.

Look at the schema - it has the discriminator in the schema

But the example leave it out.

It seems its related to the oneOf is at the root of the actual request like

If the oneOf is nested with another object it does it correctly.

Examples basically just returning the types of OneOf like

I closed this issue because of the lack of reply from OP.
Like I said earlier, I've never used IMultipleExamplesProvider myself, so I'm not gonna be able to help here.

I'm not convinced that @svha1977's issue is the same issue which OP has. I'm not gonna be able to fix either issue, so someone else will have to provide a PR.
