我使用will_paginate gem 对我的 test_app 的索引页进行分页。它只显示列出的拍卖,并且与每个拍卖相对应,有编辑、销毁功能。我的分页运行良好。我总共有 6 次拍卖以表格的方式列出,当我输入 per_page = 2 时,有 3 页。但是,当我在第 2 或第 3 页编辑和更新拍卖时,它只会在更新操作后进入第一页。我希望它保持在同一页面上。
我的观点 - Index.html.erb
<h1>Listing auctions</h1>
<table>
<tr>
<th>Name</th>
<th>Category</th>
<th>Item</th>
<th></th>
<th></th>
<th></th>
</tr>
<% @auctions.each do |auction| %>
<tr>
<td><%= auction.name %></td>
<td><%= auction.category %></td>
<td><%= auction.item_id %></td>
<td><%= link_to 'Show', auction %></td>
<td><%= link_to 'Edit', edit_auction_path(auction) %></td>
<td><%= link_to 'Destroy', auction, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</table>
<br />
<%= will_paginate @auctions %>
<%= link_to 'New Auction', new_auction_path %>
<%= link_to 'Back to Home', home_path %>
