如何在Rails中设置Datatables Editor，然后处理JSON响应？

# Gemfile
gem 'datatables-editor-rails'

# 控制器
class UsersController < ApplicationController
  include DataTables::Editor::Resources

  def index
    respond_to do |format|
      format.html
      format.json { render json: UserDatatable.new(params) }
    end
  end

  def create
    respond_to do |format|
      format.json { render json: UserEditor.new(params).create }
    end
  end

  def update
    respond_to do |format|
      format.json { render json: UserEditor.new(params).update }
    end
  end

  def destroy
    respond_to do |format|
      format.json { render json: UserEditor.new(params).destroy }
    end
  end
end

# 视图
# app/views/users/index.html.erb
<table id="users-table" class="display" style="width:100%">
  <thead>
    <tr>
      <th>Name</th>
      <th>Email</th>
      <th>Actions</th>
    </tr>
  </thead>
</table>

<script>
  $(document).ready(function() {
    $('#users-table').DataTable({
      processing: true,
      serverSide: true,
      ajax: '<%= users_path(format: :json) %>',
      columns: [
        { data: 'name' },
        { data: 'email' },
        { data: 'actions', orderable: false, searchable: false }
      ],
      dom: 'Bfrtip',
      buttons: [
        'create',
        'edit',
        'remove'
      ]
    });
  });
</script>
