我正在尝试在我的应用程序中设置 smart_listing gem。在哪里以及如何配置分页结果的默认每页数。在 smart_listing 的文档中提到它使用 kaminari。

【解决方案1】：

如果您还没有 config/initializers/kaminari_config.rb 文件，请运行 Kaminari 的配置生成器：

bundle exec rails generate kaminari:config

这将使用默认内容创建config/initializers/kaminari_config.rb：

Kaminari.configure do |config|
  # config.default_per_page = 25
  # config.max_per_page = nil
  # config.window = 4
  # config.outer_window = 0
  # config.left = 0
  # config.right = 0
  # config.page_method_name = :page
  # config.param_name = :page
end

只需取消注释并编辑您有兴趣更改的配置选项。

更新：

SmartListing 在config/initializers/smart_listing.rb 中提供了自己的分页配置选项：

SmartListing.configure do |config|
  config.global_options({
    #:param_names  => {                                              # param names
      #:page                         => :page,
      #:per_page                     => :per_page,

    #},
    #:array                          => false,                       # controls whether smart list should be using arrays or AR collections
    #:max_count                      => nil,                         # limit number of rows
    #:unlimited_per_page             => false,                       # allow infinite page size
    #:paginate                       => true,                        # allow pagination

取消注释 page_sizes 行并将 DEFAULT_PAGE_SIZES 替换为类似 [10, 20, 50, 100] 的数组

【讨论】：

我已经试过了。我不工作。该视图仅显示前三行和分页。
对我有用（重新启动服务器后..在更改配置文件中的某些内容后我偶尔会忘记做某事）！感谢您的帮助。
这个问题有点老了，但是更改配置文件对我也不起作用，当我调用 smart_listing create 时，我仍然必须覆盖我想要更改的每个参数。对于页面大小： smart_listing_create( ... page_sizes: [42, 256, 1024], ...) 这可行，但默认值肯定会更好，我无法解释为什么不加载配置文件。
此处相同，默认文件未加载

【解决方案2】：

无需在initializers/smart_listing.rb 中注释掉page_sizes。您可以在控制器中定义per_page 值，例如：

users_scope = User.all.includes(:bio)
users_scope = users_scope.like(params[:filter]) if params[:filter]
@users = smart_listing_create :users, users_scope, partial: "users/list", page_sizes: [5, 7, 13, 26]
