如何让check_box签入rails？

<%= form_with model: @user, url: user_path(@user), method: :put do |form| %>
  <%= form.check_box :interests, { multiple: true }, 'reading', 'sports' %>
  <%= form.submit 'Sign In' %>
<% end %>

class User < ApplicationRecord
  serialize :interests, Array
end

class UsersController < ApplicationController
  def update
    @user = User.find(params[:id])
    if @user.update(user_params)
      redirect_to @user, notice: 'User was successfully updated.'
    else
      render :edit
    end
  end

  private

  def user_params
    params.require(:user).permit(:interests => [])
  end
end

<%= form.check_box :interests, { multiple: true }, 'reading', 'sports' %>

class User < ApplicationRecord
  serialize :interests, Array
end

def user_params
  params.require(:user).permit(:interests => [])
end
