在Ruby中添加图像和资源后，我无法保存图书

分类: 技术问答 • 2025-08-18 09:07:28
问题描述：

我需要帮助。我正在创建一个使用ruby和amazon web服务的示例书店。我已经安装了gem'aws-sdk'，一切正常，直到我尝试用图像和资源创建新书。我收到link上列出的错误。 “app/controllers/books_controller.rb：29：在'create'”（对不起，我添加了完整跟踪，因为我认为这会有所帮助）如果我删除它建议的代码行，它可以工作，但书不会在仪表板中显示。在Ruby中添加图像和资源后，我无法保存图书

让我知道你是否需要我的任何东西。我没有把最新的提交推送到github上，因为我不想要任何错误，但是如果需要的话，我会的。 Here是没有这些功能的最新回购。

下面是我采取的步骤来达到这一点。也许我错过了什么？ 添加AWS-SDK宝石我的Gemfile

设置回形针默认为AWS S3并设置其凭据

应用程序/配置/ apllication.rb

config.paperclip_defaults = { 
storage: :s3, 
s3_credentials: { 
bucket: ENV['AWS_BUCKET'], 
access_key_id: ENV['AWS_ACCESS_KEY_ID'], 
secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'] 
} 
}

添加两个附件（：图像/：资源）的输入栏的簿册形式

<%= simple_form_for(@book, html: {class: "form-signin"}) do |f| %> 
<%= f.error_notification %> 


<%= f.input :name, required: true, label: false, placeholder: "Name", input_html: {class: "form-control"} %> 
<%= f.input :author, required: true, label: false, placeholder: "Author's name", input_html: {class: "form-control"} %> 
<%= f.input :description, required: true, label: false, placeholder: "Description", input_html: {class: "form-control", rows: 5} %> 
<br> 
<%= f.input :price, required: true, label: false, placeholder: "Price", input_html: {class: "form-control"} %> 
<%= f.input :image %> 
<%= f.input :resource %> 
<div class="checkbox text-center"> 
<p>Availability</p> 
<%= f.input :availability, required: false, label: false %> 
</div> 
<%= f.button :submit, class: "btn btn-primary btn-block" %> 
<% end %>

验证内容类型的附件，以及它们的存在

validates_attachment_content_type :image, 
content_type: /^image\/(png|gif|jpeg)/, 
message: "Only images allowed" 

validates_attachment_content_type :resource, 
content_type: ['application/pdf'], 
message: "Only pdfs allowed" 

validates :image, attachment_presence: true 
validates :resource, attachment_presence: true

然后是错误，当我尝试创建一个新的书“的书籍/新”

UPDATE：

这里是我的终端出认沽当我点击“创建书”

我决定的问题。我重新创建了桶。您必须将区域设置为“美国标准”才能使用。最初它被设置为“俄勒冈州”。

答

这是由新的aws-sdk gem引起的，请将您的gemfile更改为安装旧版本2.0以上版本

gem 'aws-sdk', '< 2.0'

它应该工作。

我试过了，仍然没有运气。仍然收到错误！ – jshuadvd 2015-03-03 05:08:11
