Should the example here ‘just work’?
I’m seeing the above error when trying to validate a file upload.
file? a formerly supported predicate?
I guess I could just validate its type, but thought the linked example looked more specific (image type and size).
Edit: To validate its type, I tried
.maybe(type?: ActionDispatch::Http::UploadedFile), but received the error:
Nothing registered with the key "action_dispatch.http.uploaded_file"
Which I gather is a known issue:
Not doing too well with this so far.
Any ideas how to validate a file upload using dry-validation within Rails? (Searching hasn’t turned up much.)
