Question

我在本文之后尝试将上传添加到我的rails项目：How To: Secure Upload。一切似乎工作正常，但我在索引视图上得到一个no方法错误：

ActionView::Template::Error (undefined local variable or method `f' for #<#<Class:0x007f690e634600>:0x007f690e620718>):
24:          
25:          <tr>
26:             <td><%= resume.name %></td>
27:             <td><%= link_to File.basename(f.resume.url), "/uploads/#{f.id}/#{File.basename(f.resume.url)}" %></td>
28:             <td><%= button_to "Delete",  resume, method: :delete, class: "btn btn-danger", confirm: "Are you sure that you wish to delete #{resume.name}?" %></td>
29:          </tr>
30:

我的模特：

class Resume < ActiveRecord::Base
    mount_uploader :attachment, AttachmentUploader # Tells rails to use this uploader for this model.
   validates :name, presence: true # Make sure the owner's name is present.
end

我的控制器：

    class ResumesController < ApplicationController
   def index
      @resumes = Resume.all
   end

   def new
      @resume = Resume.new
   end

   def create
      @resume = Resume.new(resume_params)

      if @resume.save
         redirect_to resumes_path, notice: "The resume #{@resume.name} has been uploaded."
      else
         render "new"
      end

   end
   def download
     path = "/#{resume.resume}"
   send_file path, :x_sendfile=>true
   end
   def destroy
      @resume = Resume.find(params[:id])
      @resume.destroy
      redirect_to resumes_path, notice:  "The resume #{@resume.name} has been deleted."
   end

   private
      def resume_params
      params.require(:resume).permit(:name, :attachment)
   end

end

我的索引视图：

    <% if !flash[:notice].blank? %>
   <div class = "alert alert-info">
      <%= flash[:notice] %>
   </div>
<% end %>

<br />

<%= link_to "New Resume", new_resume_path, class: "btn btn-primary" %>
<br />
<br />

<table class = "table table-bordered table-striped">
   <thead>.
      <tr>
         <th>Name</th>
         <th>Download Link</th>
         <th> </th>
      </tr>
   </thead>

   <tbody>
      <% @resumes.each do |resume| %>

         <tr>
            <td><%= resume.name %></td>
            <td><%= link_to File.basename(f.resume.url), "/uploads/#{f.id}/#{File.basename(f.resume.url)}" %></td>
            <td><%= button_to "Delete",  resume, method: :delete, class: "btn btn-danger", confirm: "Are you sure that you wish to delete #{resume.name}?" %></td>
         </tr>

      <% end %>
   </tbody>

</table>

我一直在谷歌搜索答案几个小时，似乎无法根据以前的答案追踪解决方案。如果有人被忽视，就道歉。

Answer 1

在操作方法中有一个拼写错误（以及这个操作方法aslo http://www.tutorialspoint.com/ruby-on-rails/rails-file-uploading.htm）。只需重命名@resumes - ＆gt; @resume在视图和控制器中。
