所以我在我的web应用程序上更新了heroku堆栈，并使用了ruby 3.2.2和will_paginate 4.0，但现在我的一个分页页面上收到了一个错误。我得到的具体错误是

2023-06-15T00:33:11.759517+00:00 app[web.1]: Rendered users/index.html.erb within layouts/application (Duration: 2.6ms | Allocations: 1025)

2023-06-15T00:33:11.760284+00:00 app[web.1]: 18: <table>

2023-06-15T00:33:11.760284+00:00 app[web.1]: 
2023-06-15T00:33:11.760285+00:00 app[web.1]: app/views/users/index.html.erb:16

实际代码是

<%= will_paginate %>

<table>
  <thead>
    <th></th> <!-- Icon -->
    ... a bunch of stuff you don't need to see ...
  </thead>
  <tbody>
    <%= render @users %>
  </tbody>
</table>

<%= will_paginate %>

我找不到任何关于will_paginate 4.0的清晰文档，说明为什么会抛出wrong number of arguments (given 4, expected 3)的特定错误。我唯一能找到的是新的基本will_paginate用法https://github.com/mislav/will_paginate。我是否需要以某种方式将我曾经分页的表捆绑到一个新的结构中？
任何帮助将不胜感激。

新版本的will_paginate不再将选项哈希作为其第三个参数。相反，所有选项都应该作为关键字参数传递。因此，您的代码应该更改为：

<%= will_paginate @users, per_page: 10 %>

<table>
  <thead>
    <th></th> <!-- Icon -->
    ... a bunch of stuff you don't need to see ...
  </thead>
  <tbody>
    <%= render @users %>
  </tbody>
</table>

<%= will_paginate @users, per_page: 10 %>

per_page选项用于指定每页应显示多少条记录。在这种情况下，我们将其设置为10。
您还可以将其他选项作为关键字参数传递给will_paginate。例如，您可以传递renderer选项来指定自定义分页呈现器。
