更新了heroku堆栈，现在出现了will_paginate错误

Question

因此，我在网络应用程序上更新了 Heroku 堆栈，并使用 ruby 3.2.2 和 will_paginate 4.0，但现在在我的分页页面之一上收到错误。我收到的具体错误是

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

2023-06-15T00:33:11.760285+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 %>

我在 will_paginate 4.0 上找不到任何明确的文档来说明为什么会抛出

wrong number of arguments (given 4, expected 3)

的特定错误。我唯一能找到的是这里使用的新的基本 will_paginate https://github.com/mislav/will_paginate。我是否需要以某种方式将我用来分页的表格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第三个参数。相反，所有选项都应作为关键字参数传递。所以，你的代码应该更改为：

<%= 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。在本例中，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渲染器。
