Attachment_fu and mime type issues

Rails
1

Hi All,
I am having a problem with the attachment_fu plugin and flac audio
files. In
the dev environment, using mongrel, the form upload object does not seem
to
have any associated content_type. I get the following attachment_fu
validation error: “Content type can’t be blank”. I don’t understand why
the
file_data would not have any content_type. Doesn’t rails set the content
type based on the mime type? How is it that a file can be uploaded
without
any mime type at all? Shouldn’t it at least have
application/octet-stream if
the server can’t parse the actual file type? I tried starting mongrel
with:
mongrel_rails start -m config/mime_types.yml
and my mime_types.yml file reads:

.flac: audio/flac

But this hasn’t helped. Are these configuration loaded mime types only
used
for serving files, and not for associating a content type with uploaded
form
data?

Thanks in advance for any tips.

I looked into this further, and discovered that with Fireforx uploading
of
flac files works: the content_type is set to ‘application/octet-stream’.
So,
the problem must be related to safari’s handling of mime types for
binary
files. I’ll have to look into that.
thanks,
