From 32b2942946edba6a288c6b992109598eeb626964 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Janko=20Marohni=C4=87?= Date: Sat, 23 Feb 2019 23:10:20 +0100 Subject: Restore UploadedFile compatibility with IO.copy_stream In https://github.com/rails/rails/pull/28676 the `#to_path` method was added to `ActionDispatch::Http::UploadedFile`. This broke usage with `IO.copy_stream`: source = ActionDispatch::Http::UploadedFile.new(...) IO.copy_stream(source, destination) # ~> TypeError: can't convert ActionDispatch::Http::UploadedFile to IO (ActionDispatch::Http::UploadedFile#to_io gives Tempfile) Normally `IO.copy_stream` just calls `#read` on the source object. However, when `#to_path` is defined, `IO.copy_stream` calls `#to_io` in order to retrieve the raw `File` object. In that case it trips up, because `ActionDispatch::Http::UploadedFile#to_io` returned a `Tempfile` object, which is not an `IO` subclass. We fix this by having `#to_io` return an actual `File` object. --- actionpack/lib/action_dispatch/http/upload.rb | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'actionpack/lib') diff --git a/actionpack/lib/action_dispatch/http/upload.rb b/actionpack/lib/action_dispatch/http/upload.rb index 827f022ca2..0da8f5c14e 100644 --- a/actionpack/lib/action_dispatch/http/upload.rb +++ b/actionpack/lib/action_dispatch/http/upload.rb @@ -20,7 +20,6 @@ module ActionDispatch # A +Tempfile+ object with the actual uploaded file.
