[FromForm] attributed model is not showed in swagger.json.components.schemas

[Moskvinr]

I need to read properties from components.schemas, but [FromForm]FormExample form is not recognized and not showed in schema.
V 5.5.0

[domaindrivendev]

Form schema's are defined inline (as opposed to being a reference to shared schema in components.schemas) and are therefore never written to components.schema.

@domaindrivendev we also noticed that Document Filters are ignored for schemas that are defined inline. Is there a way to modify inline schemas?

[max-arshinov]

@domaindrivendev any updates?

[domaindrivendev]

Due to the way in which form fields are surfaced by ApiExplorer (the API metadata layer that ships with ASP.NET Core), form Schema's need to be treated as a special case in Swashbuckle, and are generated in a slightly different way to to regular payload schemas.

As a result, they are a) always generated inline within the relevent Operation definition rather components.schemas and b) never passed through the schema filters.

If you need to inspect those schemas, look in the relevent Operation definition instead. If you need to modify, use an IOperationFilter instead of an ISchemaFilter.
