Attachments aren't displaying on the status (:user_id is nil?)

I've been trying to figure this out on my own, but I think I need another brain to think this through with me. For some reason my attachments aren't displaying. They are attaching just fine (since I can find them in my public folder), but from what I can tell they are not connecting to the user properly.

I opened up the rails console and looked at the information associated with the documents as well as the statuses and I noticed that the ":user_id" for the document is nil. I also noticed that the ":document_id" for the status is nil. I thought this was related to something wrong with my db, checked the schema, noticed the add_index "documents", ["user_id"] wasn't in there even though I did that in the migration file. I reset the db and it finally showed up, but it didn't fix my problem.

Any other thoughts as to why this may not be working? I've checked and re-checked my text for typos, but I don't see any, so maybe I just need another set of eyes. Please and thank you!
