Rails - Jul 2006 - file_column - assigning with an actual file rather than a multipart

Hi there,

I''m using the wonderful file_column and have struck an issue that
someone might have seen before.

My images already sit on the server. So, instead of passing a
multipart message I''m sending a file object.

Something like...

f = File.new("public/gallery_images/builder.png")
p = Product.find_first
p.image = f
p.save

On the save I recieve an error which I''ve pasted at the bottom of this
mail.

A temporary image is created in the correct place so I''m almost there.
Any ideas? I haven''t heard of anyone doing this but file_column.rb#47
said I could.

Thanks

Oops, dont worry about that... I had the field type set to integer
rather than string. Good one dumbdumb.
