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

Peace,

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.
