问题

我在我的网站上具有此搜索功能，但可以使用Meetings，但只有Meetings不能使用。当我尝试使用Meeting链接到asset_path包含的pdf文件时，我得到了404页面。

这是我的会议模型

    class Admin::Meeting < ApplicationRecord

        # Image/File Uploader
        mount_uploader :agenda, FileUploader
        mount_uploader :minutes, FileUploader

        has_many :meeting_translations, dependent: :destroy
        accepts_nested_attributes_for :meeting_translations

     end

我的文件上传器如下所示，我使用的是CarrierWave

class FileUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:
  # require 'RMagick'

  # include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # before :cache, :setup_available_sizes
  # before :cache

  # Choose what kind of storage to use for this uploader:
  storage :file
  permissions 0777  
  # storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.name.demodulize.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url(*args)
  #   # For Rails 3.1+ asset pipeline compatibility:
  #   # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
  #
  #   "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  # end

  # Process files as they are uploaded:
  # process scale: [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  # version :thumb do
  #   process resize_to_fit: [200, 200]
  # end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_whitelist
    %w(pdf doc docx xls xlsx)
  end

  def size_range
    1..10.megabytes
  end

end

这是我尝试链接到agenda（agenda是文件）的视图

<% @meeting_results.each do |result| %>
       <% unless result.agenda.nil? %>
         <div class="col-sm-12">
           <div class="col-sm-1"><i class="far fa-file-pdf fa-2x" aria-hidden="true"></i></div>
             <div class="col-sm-10">
               <div class="results-link">
                 <a href="<%= asset_path result.agenda %>"><%= result.agenda.file.original_filename %></a>
               </div>
             </div>
           </div>
        <% end %>
      <% end %>

这是我得到的错误

404_error

当我链接到PDF时，通常不会出现此问题，我不知道是否是因为还有minutes的另一个文件Meeting吗？无论如何，感谢您的帮助。

修改

我还注意到，从asset_path返回的路径不包含Meeting的ID。当文件确实位于uploads/meeting/agenda/Bathurst_Regular_Public_Meeting_Agenda_May_15-2017.pdf

中时，这是给我uploads/meeting/agenda/ID/Bathurst_Regular_Public_Meeting_Agenda_May_15-2017.pdf的路径

Answer 1

我觉得自己是个白痴，我对查找与搜索字词匹配的会议的查询是错误的。

我所拥有的

我替换为

@meeting_results = Admin::Meeting.select(:agenda).where("meetings.agenda LIKE ? OR meetings.minutes LIKE ?", "%#{query}%", "%#{query}%").distinct

由于进行了更改，因此我输入了错误的查询，因此决定不进行更改。希望有一天能对某人有所帮助：（
