Paperclip patch problems

hmm, not sure why I’m getting this error or know how to resolve it. I followed the paperclip tutorial and it seemed quite straight forward. I bundled the gem, added the necessary attachment to the model I’m using, and ran rake db:migate. It created all the necessary columns for that table.

I have the multipart form for and file chooser, that seems to work correctly on the new/edit page.

but, when I attempt to save it, it gives me

No route matches [PATCH] “/receivings”

I do have the resource in the routes file, not sure what is wrong?
