在回形针中查看照片时出现问题 - 路线错误
我已在系统上成功设置 Paperclip 和 ImageMagick，并且文件正在正确上传、调整大小并保存到正确的文件夹中。
我尝试在我的视图中显示这些图像：
<%= image_tag @customer.logo.url(:medium) %>
没有显示图像。当我访问图像的直接 url 时，我得到：
Routing Error
No route matches "/images/assets/logos/1/medium/corplogo.jpg" with {:method=>:get}
这是一个仍在开发中并在 Windows 上运行的本地服务器。我的表单是多部分的：
<% form_for @customer, :url => {:action => "update", :id => @customer}, :html => {:multipart => true, :id => "myform"} do |f| %>

I have set up Paperclip and ImageMagick successfully on my system, and files are uploading correctly, being resized, and and being saved into the right folders.
I try to display those images in my view:
<%= image_tag @customer.logo.url(:medium) %>
No image is displayed. When I go to the image's direct url I get:
Routing Error
No route matches "/images/assets/logos/1/medium/corplogo.jpg" with {:method=>:get}
This is a local server still in development and running on Windows. My forms are multipart:

我找到了问题的答案，它在于模型中的 url 声明。
而不是：
应该是：
I found the answer to the problem, and it lies with the url declaration in the model.
Instead of:
it should be:
我使用“webrick”服务器时遇到此错误。我检查了“public/system”文件夹上的所有文件访问权限，它们都是正常的。
最后我切换到 apache/passenger，它有效，图像显示正确。
I got this error using the "webrick" server. and I check all the file access permission on my "public/system" folder, they are normal.
finally I switched to apache/passenger, it works, the images are displayed correctly.
