order--正序倒序-select

参考：https://apidock.com/rails/ActiveRecord/QueryMethods/order

视图页面

<%= form_tag '', method: :get do %>
 总数: <%= select_tag :order, options_for_select([['不排序', nil],['升序', 'asc'],['降序', 'desc']], params[:order]) %>
<%= submit_tag raw("&#xf002; 查询"), class: "form_submit", class: 'btn btn-secondary btn-sm fa-input' %>
 <%= link_to raw('<i class="fa fa-download"></i>下载csv'), download_csv_accounts_path, class: "btn btn-primary btn-sm"%>
<% end %>

controller页面增加判断

@accounts = Account
     if params[:order] == 'asc'
       @accounts = @accounts.order('nft_asset_count ASC')
   elsif params[:order] == 'desc'
      @accounts = @accounts.order('nft_asset_count DESC')
    else
     @accounts = @accounts.order('id desc')
   end

@accounts = @accounts.page(params[:page]).per(100)
