Rails：用回形针上传文件 [英] Rails: uploading files with paperclip

问题描述

我想用回形针上传文件。使用基本的开箱即用设置，我能够将文件上传到默认目录（公共/系统中的某些东西）。但是，当我尝试更改url或路径（或两者）时：

  class Cvit< ActiveRecord :: Base 
 has_attached_file：fileup，：path => ：rails_root / public / data / 01_fasta
 end 
  

我失去了01_fasta目录，在做了一个chmod 777之后，我注意到这个文件在那里，但是它的名字像stream20110706-45944-12lt2oo-0

也尝试了＃{rails_root}代替：rails_root。

什么是交易????

解决：：url和：路径需要指向一个文件，而不是一个目录。所以我必须要有类似于

  class Cvit< ActiveRecord :: Base 
 has_attached_file：fileup，
：url => /data/01_fasta/:basename.:extension，
：path => ：rails_root / public / data / 01_fasta /：basename。：extension
 end 
  

解决方案

  class Cvit< ActiveRecord :: Base 
 has_attached_file：fileup，
：url => /data/01_fasta/:basename.:extension，
：path => ：rails_root / public / data / 01_fasta /：basename。：extension
 end 
  

I would like to use paperclip to upload files. With the basic out of the box settings, I was able to get the file uploaded to the default directory (something in public/systems...) However when I tried changing the url or path (or both):

class Cvit < ActiveRecord::Base
    has_attached_file :fileup, :path => ":rails_root/public/data/01_fasta"
end

I lose permission to the 01_fasta directory, after doing a chmod 777 on it, I notice the file is there but its named something like, stream20110706-45944-12lt2oo-0

also tried #{rails_root} in place of :rails_root.

Whats the deal????

SOLVED: the :url and :path need to point at a file, not a directory. So I had to have something like

class Cvit < ActiveRecord::Base
  has_attached_file :fileup,
    :url => "/data/01_fasta/:basename.:extension",
    :path => ":rails_root/public/data/01_fasta/:basename.:extension"
end
