_list.html.erb中的Rails 6文件可怕的语法错误

Question

我将以http://filterrific.clearcove.ca/pages/action_view_api.html为例，尽可能地在一个玩家模型上设置简单的过滤。然而，我一直收到下面的语法错误，显然我在这里遗漏了一些东西！

错误

syntax error, unexpected '<', expecting ')'
  </div>
  ^
/home/jack/Itorix/app/views/players/_list.html.erb:10: unknown regexp options - th

播放器控制器

def index
    @filterrific = initialize_filterrific(
      Player,
      params[:filterrific]
    ) || return
    @players = @filterrific.find.page(params[:page])
     respond_to do |format|
      format.html
      format.js
    end
  end

玩家模型

class Player < ApplicationRecord
    filterrific(
        default_filter_params: { sorted_by: 'tornid' },
        available_filters: [
     :sorted_by,     
   ])
      scope :sorted_by, ->(sort_option) {
  # extract the sort direction from the param value.
  direction = /desc$/.match?(sort_option) ? "desc" : "asc"
  case sort_option.to_s
  when /^tornid/
    # Simple sort on the created_at column.
    # Make sure to include the table name to avoid ambiguous column names.
    # Joining on other tables is quite common in Filterrific, and almost
    # every ActiveRecord table has a 'created_at' column.
    order("players.tornid #{direction}")

  else
    raise(ArgumentError, "Invalid sort option: #{sort_option.inspect}")
  end
}
end

    <%= page_entries_info players # provided by will_paginate %>
  </div>

  <table>
    <tr>
      <th><%= filterrific_sorting_link(@filterrific, :tornid) %></th>
    </tr>
    <% players.each do |player| %>
      <tr>
        <td><%= player.tornid %></td>

      </tr>
    <% end %>
  </table>
</div>

<%= will_paginate players # provided by will_paginate %>

Answer 1

正好遇到了这个问题，并通过删除_list文件中的内联注释解决了这个问题。从page_entries_info和will_paginate中删除# provided by will_paginate，语法错误就会消失。
