レールアプリの認証にdeviseを使用していますが、すべてうまくいきますが、ポストモデルがあり、新しい投稿を作成しようとするとサインアップした後にエラーが表示されます：許容されていないパラメータ：レールのuser_idエラー
1 error prohibited this post from being saved:

私のユーザモデル
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :posts
end
マイポストモデル
class Post < ApplicationRecord
belongs_to :user
end
私はまた、この移行を介してユーザにuser_idを追加しました：あなたはあなたのモデルに列を追加する場合
class AddUseridToPost < ActiveRecord::Migration[5.0]
def change
add_column :posts, :user_id, :integer
end
end
許可する必要はありません：user_idも？ –
