Question

所以我刚刚安装了paperclip，并试图让它在我全新的Rails应用程序中运行。

但是当我转到localhost / upload / new：

时，这是我一直得到的错误

NoMethodError in Upload#new
undefined method `uploads_path' for #<#<Class:0x00000102d1b8e0>:0x00000102cf24e0>
Extracted source (around line #3):

1: <h1>Upload Images</h1>
2: 
3: <%= form_for @upload, :html => { :multipart => true } do |f| %>
4:  <%= render 'fields', :f => f %>
5:  <div>
6:      <%= f.submit "Upload" %>

我用Paperclip解决了另一个错误，在config / application.rb文件中包含以下行：

Paperclip::Railtie.insert

我的应用程序结构的方式是我创建了一个名为“上传”的模型，因为该应用程序将管理各种文件类型 - 由用户上传。 Paperclip正在管理图像。

上传控制器如下所示：

class UploadController < ApplicationController
  def index
  end

  def show
  end

  def new
    @upload = Upload.new
    @title = "Upload"
  end

  def edit
  end

  def delete
  end

end

所以我的上传模型如下所示：

class Upload < ActiveRecord::Base
    attr_accessible :name, :description, :type

    has_attached_file :image
end

这是我的new.html.erb文件的外观：

<h1>Upload Images</h1>

<%= form_for @upload, :html => { :multipart => true } do |f| %>
    <%= render 'fields', :f => f %>
    <div>
        <%= f.submit "Upload" %>
    </div>
<% end %>

部分看起来像这样：

<%= render 'shared/error_messages', :object => f.object %>
<div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name %>
</div>
<div class="field">
    <%= f.label :description %><br />
    <%= f.text_field :description %>
</div>
<div class="field">
    <%= f.label :type %><br />
    <%= f.text_field :type %>
</div>
<div class="field">
    <%= f.file_field :image %>
</div>

P.S。我只是在学习Rails，所以如果有菜鸟/菜鸟的错误，请不要把我钉在十字架上：|

感谢。

在地图文件中，添加：

对于Rails 2.x：

map.resources :uploads

对于Rails 3.x：

resources :uploads

这将添加7个RESTful操作的所有路由，然后users_path将起作用。

回形针和导轨3 - NoMethodError
