Answer 1

Vergewissern Sie sich immer, dass Sie die gesamte Fehlermeldung gelesen haben.

Es sieht aus wie Sie einen Rechtschreibfehler additonals (aus dem „Hast du Mean“) haben

Höchstwahrscheinlich werden Sie Dinkel Ihre has_many :additionals Beziehung falsch.

Answer 2

Im Patient Modell Sie haben:

has_many :additonals 

Es sollte:

has_many :additionals
