Thanks a lot for the latest release and also for the whole library. It’s really useful for me.
One thing I am not sure how to do is something like “polymorphic” schemas. This could be used for example with an endpoint returning 409 (conflict) with multiple meanings.
For example for one endpoint it means email is already registered or email is already invited. For some other endpoint 409 could mean some other options. I know I can create new Error.Conflict* schema for each endpoint and use the enum: [ ... ] atribute, but this could become quite non-DRY after a while.
I would really like something like
409 => {"Conflict", "application/json", Api.Schema.Conflict.new("email_already_registered", "email_already_used")
with the schema defined like this:
defmodule Api.Schema.Conflict do
require OpenApiSpex
alias OpenApiSpex.Schema
def new(enum) do
OpenApiSpex.schema(%{
title: "Error.Conflict",
type: :object,
properties: %{
error: %Schema{
type: :object,
properties: %{
name: %Schema{
type: :string,
enum: enum,
required: true
},
message: %Schema{type: :string}
}
}
}
})
end
end
Is it possible or am trying to use a completely wrong approach?
