Rails fields_forがうまくいきません

Question

現在複数のモデルの情報を一括で保存するフォームを作成しています。

以下のようなエラーが出て丸一日解決せず、皆様の知見をお借りしたいです。

エラー文

ActiveModel::UnknownAttributeError at /family/tops
unknown attribute 'vitals_attributes' for Vital.

なぜかストロングパラメータで_attribeの部分がカラムとして認識されているようで、引っかかってしまいます。。

モデル

class Family < ApplicationRecord
  has_secure_password
  
  has_many :vitals
  accepts_nested_attributes_for :vitals
  has_many :bathing_days
  accepts_nested_attributes_for :bathing_days
  has_many :intake_waters
  accepts_nested_attributes_for :intake_waters
  has_many :medicines
  accepts_nested_attributes_for :medicines
  has_many :excretas

Answer 1

current_family.vitals.create!(family_params)
ここでは　Family をつくらずに Vital を作っています。
Viatlには accepts_nested_attributes_for :vitals していないです
current_family.vitals.create!(family_params[:vitals_attributes])
