Because option `file -bi …`
returns ‘regular_file’ instead of something like ‘image/jpeg’ on Mac OS-X

It works. attachment_fu requires default naming of some form variables to make things work. Be certain that your incoming parameters hash has a filename and uploaded_data parameter set. In Flex, you can set the name of your uploaded file with

file.upload(request, “uploaded_data”);

where file is a FileReference object.

1. how does the rails controller code look like? how are you guys constructing model object out of posted data?

thx

I’ve integrated these changes you’ve made into the Ruboss “Flexible Rails” framework to allow file uploading (as well as Restful_Authentication) to be possible from Flex to Rails. Thanks for all of your help. I haven’t completely finished the Flex part yet, but this tutorial was great.

Here’s the beginnings of a RESTful Flex on Rails social networking site. Just laying the groundwork a little bit. Ruboss Tutorial

However your fix didn’t work for me, it always called the rescue block, so I commented that out and then did some dumping of the various variables, the results for content_type (after the file -bi “#{File.join(temp_path)} part was):

ERROR: cannot open `â??/tmp/CGI4338-1â??’ (No such file or directory)

I had no idea what was going on as the temp_path was:

/tmp/CGI4338-1

I couldn’t figure this out so I added the following hack to the rescue block:

content_type = Mime::Type.lookup_by_extension( File.extname( self.filename ).gsub( /\./, ” ) )
if content_type.to_s.match( /.*\/.*/ )
content_type.to_s
else
fallback
end

I don’t really like this, but it works (I’ve registered the appropriate mime types with Mime::Type.register). Do you have any idea what that error is on the file -bi line.

Anyway it was still a great help to come across this post as it didn’t mean I spent as long figuring out why the thumbnails weren’t being created.

Thanks again.
