NoMethodError“退出状态”在 Ruby on Rails 中使用 Paperclip 时

发布于 2024-12-06 21:04:24 字数 11109 浏览 3 评论 0原文

我正在尝试使用回形针来处理 Rails 应用程序中的文件上传。我目前在 Rails 3.0.9 上运行 Paperclip 2.4.1，在 sqlite3 上运行 WEBrick 服务器。

在添加文件上传部分之前，该表单工作正常，但在按照 Paperclips 文档 (http://rdoc.info/gems/paperclip/2.4.1/file/README.md) 中的快速入门说明进行操作后，在提交表单时，我得到了以下错误：

undefined method `exitstatus' for nil:NilClass 
at app/controllers/shows_controller.rb:62:in `create'

这是我的模型的代码：

class Show < ActiveRecord::Base
  has_many :pictures
  has_attached_file :thumb, 
                :styles => { :thumb => "150x150>" },
                :url => "/images/:id/thumb.:extension"

  validates_attachment_presence :thumb
  validates_presence_of :title 
  validates_presence_of :start_date 
  validates_presence_of :end_date
  validates_presence_of :description
  validates_presence_of :blurb 
  validates_presence_of :location

  def self.current
    where("shows.end_date > ?", Time.new).first
  end

  def self.thumb
    image_tag self.thumb.url(:thumb)
  end

end

我的控制器的创建方法：（

def create

@show = Show.create(params[:show])

respond_to do |format|
  if @show.save
    format.html { redirect_to(@show, :notice => 'Show was successfully created.') }
    format.xml  { render :xml => @show, :status => :created, :location => @show }
  else
    format.html { render :action => "new" }
    format.xml  { render :xml => @show.errors, :status => :unprocessable_entity }
  end
end

第 62 行是 @show = Show.create(params[:show] 行)）

我的表单：

<%= form_for @show, :html => {:multipart => true} do |f| %>
  <% if @show.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@show.errors.count, "error") %> prohibited this show from being saved:</h2>

      <ul>
      <% @show.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </div>
  <div class="field">
    <%= f.label :start_date %><br />
    <%= f.date_select :start_date %>
  </div>
  <div class="field">
    <%= f.label :end_date %><br />
    <%= f.date_select :end_date %>
  </div>
  <div class="field">
    <%= f.label :description %><br />
    <%= f.text_area :description %>
  </div>
  <div class="field">
    <%= f.label :blurb %><br />
    <%= f.text_field :blurb %>
  </div>  
  <div class="field">
    <%= f.label :location %><br />
    <%= f.text_field :location %>
  </div>
  <div class="field">
    <%= f.label :thumb %><br />
    <%= f.file_field :thumb %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

我是'桌子在其他地方找到与回形针相关的此错误的任何实例；它看起来像是从 Rails 内部的某个地方冒出来的；有什么建议吗？

原文

I'm trying to use paperclip to handle file uploads in my Rails app. I'm currently running Paperclip 2.4.1 on Rails 3.0.9, running a WEBrick server on sqlite3.

The form worked fine before adding the file upload portion, but after following the quickstart instructions in the Paperclips docs (http://rdoc.info/gems/paperclip/2.4.1/file/README.md), upon form submission I get the following error:

undefined method `exitstatus' for nil:NilClass 
at app/controllers/shows_controller.rb:62:in `create'

Here's the code for my model:

class Show < ActiveRecord::Base
  has_many :pictures
  has_attached_file :thumb, 
                :styles => { :thumb => "150x150>" },
                :url => "/images/:id/thumb.:extension"

  validates_attachment_presence :thumb
  validates_presence_of :title 
  validates_presence_of :start_date 
  validates_presence_of :end_date
  validates_presence_of :description
  validates_presence_of :blurb 
  validates_presence_of :location

  def self.current
    where("shows.end_date > ?", Time.new).first
  end

  def self.thumb
    image_tag self.thumb.url(:thumb)
  end

end

The create method for my controller:

def create

@show = Show.create(params[:show])

respond_to do |format|
  if @show.save
    format.html { redirect_to(@show, :notice => 'Show was successfully created.') }
    format.xml  { render :xml => @show, :status => :created, :location => @show }
  else
    format.html { render :action => "new" }
    format.xml  { render :xml => @show.errors, :status => :unprocessable_entity }
  end
end

(Line 62 is the @show = Show.create(params[:show] line))

My form:

<%= form_for @show, :html => {:multipart => true} do |f| %>
  <% if @show.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@show.errors.count, "error") %> prohibited this show from being saved:</h2>

      <ul>
      <% @show.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </div>
  <div class="field">
    <%= f.label :start_date %><br />
    <%= f.date_select :start_date %>
  </div>
  <div class="field">

    <%= f.date_select :end_date %>
  </div>
  <div class="field">

    <%= f.text_area :description %>
  </div>
  <div class="field">

    <%= f.text_field :blurb %>
  </div>  
  <div class="field">

    <%= f.text_field :location %>
  </div>
  <div class="field">
    <%= f.label :thumb %><br />
    <%= f.file_field :thumb %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

I wasn't able to find any instance of this error elsewhere relating to paperclip; It looks like its bubbling up from within Rails somewhere; any suggestions?

似乎用可卡因运行的命令不正确。您是否使用 Paperclip.options[:command_path] = "/usr/local/bin/" 配置了 paperclip 的命令路径并在此路径中安装了 ImageMagick？

您可以使用 which Convert 找出 ImageMagick 的位置。这应该产生 ImageMagick 转换二进制文件的路径 - 在我的例子中 /usr/local/bin/convert

It seems that the command, that is run with cocaine is not correct. Have you configured paperclip's command path with Paperclip.options[:command_path] = "/usr/local/bin/" and installed ImageMagick in this path?

You can find out where ImageMagick is with which convert. This should yield the path to the convert binary of ImageMagick - in my case /usr/local/bin/convert
