如何在simple_form_for中创建具有2个嵌套属性和复选框的表

gem 'simple_form'

<%= simple_form_for @post do |f| %>
  <%= f.input :title %>
  <%= f.input :content %>
  
  <%= f.simple_fields_for :comments do |c| %>
    <%= c.input :author %>
    <%= c.input :body %>
  <% end %>
  
  <%= f.input :published, as: :boolean %>
  
  <%= f.button :submit %>
<% end %>

class PostsController < ApplicationController
  def new
    @post = Post.new
    @post.comments.build
  end
  
  def create
    @post = Post.new(post_params)
    if @post.save
      # 处理保存成功后的逻辑
    else
      # 处理保存失败后的逻辑
    end
  end
  
  private
  
  def post_params
    params.require(:post).permit(:title, :content, comments_attributes: [:author, :body])
  end
end
