ActiveRecord :: UnknownAttributeError: Unbekanntes Attribut 'user_id' für Beitrag

Question

Ich laufe in den folgenden Fehler beim Ausführen meiner Tests. Die Bedingung für den Test besteht darin, dass der Benutzer angemeldet sein muss, um Posts zu erstellen. ähnliche Fehler scheinen hauptsächlich mit foreign_key zu funktionieren, aber ich habe es anscheinend. Jede Hilfe wird sehr geschätzt. Vielen Dank!

Failure/Error: @post = current_user.posts.build(post_params)
