Ruby on rails 3 上传附件时未调用回形针，因此附件不会保存。Rails3+上传

我有两个不同的应用程序使用回形针。在不保存附件或调用回形针的应用程序上，我上传应用程序时会收到此日志

您是否记得在视图中的表单标记中添加：multipart=>true？

尝试将：document\u file\u名称添加到attr\u可访问调用。

我注意到的一件事是，您的要点中uploadify的第17行有一个输入错误。你有dat.upload，可能应该是data.upload

---

另外，您是否尝试过一次取消一个验证的注释？让我知道会发生什么。我也经历过与回形针的战争。

我和你做的事情完全一样，但使用aws-s3 gem帮助我通过回形针上传到s3。这是我的模型中的内容：

has_attached_file :image,
                :storage => :s3,
                :s3_credentials => "#{Rails.root.to_s}/config/s3.yml",
                :bucket => "your_s3_bucket_name",
                :path => ":attachment/:id/:style/:filename"

我的档案里有这个：

gem "paperclip", "~> 2.3"

gem "aws-s3"

在我的分组表中：

t.string   "image_file_name"
t.string   "image_content_type"
t.integer  "image_file_size"
t.datetime "image_updated_at"

哈，我打算提出同样的建议。那一次不止一次地让我着迷！谢谢，但是在将：document\u file\u name添加到attr\u accessible调用之后，它仍然无法正常工作，除非我注释掉“has\u attached\u file:document”部分和验证。哦，好吧，这只是一个想法。我以前有一个困难的错误，当我没有：文档作为属性可访问。谢谢你的建议。我已经更正了拼写并检查了验证，现在看来还可以，但是如果“has_attached_file:document”有任何选项，附件仍然不起作用。另外，我看到两个路由错误。一个是当曲别针调用'SELECT'而不是'INSERT'时，第二个是当我调用localhost:3000/users/1/uploads时，它调用uploads/index.html.erb。感谢Againga我们真的看到了你的表单代码？SELECT语句不是用来获取用户信息以验证身份验证令牌的吗？@CharlieMezak，感谢你对这个问题给予了赏金。表单部分文件和其他视图文件已附加。@Joseph。谢谢，但我不认为SELECT语句是用来吸引用户的，因为当我从纸夹的**'has_many_attachment:document'中注释出：url和：path选项时，会调用INSERT语句，虽然它保存了文件，但最终会在网站上显示我的密码、真伪令牌等。啊，我明白了，我们绝对不希望发生这种事，汉克斯。您是否建议usinh附上文件“文档”。我运行**rails生成回形针上载文档，而不是rails生成回形针上载图像。您认为文档是rails中的保留字吗。再次感谢。
