如果有人能帮我解决以下问题，那就太好了。

我是初学者，目前遇到以下错误：ArgumentError in Users::MerchantsController#new "unknown keyword: :merchant_attributes"

使用 rails 7，设计和转换，我有一个用户表，以及消费者和商家等角色。对于商家角色，我喜欢通过子表添加地址信息，应通过单独的注册表单提交。

不知何故，我在控制器上遇到错误 - devise_parameter_sanitizer.permit -
:merchant_attributes

这就是它现在的样子。

用户.rb

class User < ApplicationRecord
  has_one :user_merchant, dependent: :destroy
  has_one :merchant, through: :user_merchant, dependent: :destroy
  
  devise :database_authenticatable, :registerable,
  :recoverable, :rememberable, :validatable

  rolify

  after_create :assign_default_role

  accepts_nested_attributes_for :merchant, allow_destroy: true

商人.rb

    class Merchant < ApplicationRecord
      belongs_to :user
    end

用户/merchants_controller.rb

# frozen_string_literal: true
class Users::MerchantsController < Devise::RegistrationsController
  prepend_before_action :require_no_authentication, only: [:new, :create, :cancel]
  before_action :configure_sign_up_params, only: [:new, :create]
  before_action :configure_account_update_params, only: [:update]

  # GET /merchants/sign_up
  def new
    # super
    super do |resource|
      resource.merchant.build
    end 
  end

  # POST /merchants
  def create
    super
    
  end

  # GET /merchants/edit
  def edit
    super
  end

  # PUT /merchants
  def update
    super
  end

  # DELETE /merchants
  # def destroy
  #   super
  # end

  # GET /resource/cancel
  # Forces the session data which is usually expired after sign
  # in to be expired now. This is useful if the user wants to
  # cancel oauth signing in/up in the middle of the process,
  # removing all OAuth session data.
  # def cancel
  #   super
  # end

  protected

  # If you have extra params to permit, append them to the sanitizer.
  def configure_sign_up_params
    devise_parameter_sanitizer.permit(
                    :sign_up, keys: [:email, :password],
                    merchant_attributes: [:user_id, :id, 
                    :organization_name, :address, :postal_code,
                    :city, :first_name, :last_name, :phone
                    ])
  end

  #   super(resource)
  # end

  # The path used after sign up for inactive accounts.
  # def after_inactive_sign_up_path_for(resource)
  #   super(resource)
  # end
end

user_merchant.rb

<div class="cb-title">Sign Up Merchant</div>

            </div>

            <%# ... %>

            <div class="col-span-full">
              <%= mf.label :phone, class: "sr-only" %>
              <%= mf.telephone_field :phone, autocomplete: "tel", class: "form-field", placeholder: "Phone number" %>
            </div>
          <% end %>
        </fieldset>

      </div>
      <div class="px-4 py-4 grid gap-4 bg-gray-50 border-t border-gray-200">
        <button type="submit" class="btn">
          <%= f.submit "Sign up" %>
        </button>
      </div>
    <% end #form %>

我不知道哪里出错了，我查找了多个似乎做同样的例子。但显然我没有做对。
