I cannot seem to get paperclip working for my file uploads after  
switching from attachment\_fu. I have the correct fields migrated into  
the database, have included has\_attached\_file :photo, :styles =\>  
{ :thumb =\> “175x175\>” } in my mode, but no photo is ever saved in the  
database and there are no errors. Looking in the console I noticed  
that it says paperclip is “Saving files for photo” and then on the  
next line “Deleting files for photo”. Im wondering if this is a clue  
to my problem? The surrounding output is below:

This is my controller action(for testing):

def update  
@spec = logged\_in\_user.spec || logged\_in\_user.spec.build(params  
[:spec])  
@spec.update\_attributes(params[:spec])  
end

Anyone have any ideas, this is driving me crazy.

If you can see the file name and not something like :  
“photo”=\>#ActionController::UploadedStringIO:0xb70611f4

There’s a mistake. Maybe you forgot the multipart on the form?
