Rails 回形针 img 上传错误:“未选择文件"安装了 rmagick [英] Rails paperclip img upload error: "no file chosen" with rmagick installed

问题描述

我无法使用回形针上传图片.每当我选择文件并提交页面时，都会重新加载并显示未选择文件".

I can't get to upload images using paperclip. Whenever I choose the file and submit the page reloads and says "no file chosen".

我的代码trip.rb

My code trip.rb

    class Trip < ActiveRecord::Base
       has_many :images
       accepts_nested_attributes_for :images, :allow_destroy => true
       attr_accessible :messages_attributes
    end 

表格

    <%= f.fields_for :images do |image_fields| %> 
       <% if image_fields.object.new_record? %> 
         <%= image_fields.file_field :image %>  
       <% end %> 
    <% end %>

图片.rb

    class Image < ActiveRecord::Base
     belongs_to :trips

     has_attached_file :image, :styles => { :large => "640x480", :medium => "300x300>", :thumb => "100x100" },
     :storage => :s3,
     :bucket => 'Thrill',
     :s3_credentials => {
       :access_key_id => 'XXXXXXXXXXXX',
       :secret_access_key => 'xxxxxxxxxxxxxxxxxxxxx'
     }
    end

而且我还在我的 gem 文件中安装了 gem 'rmagick'，这似乎是许多有类似问题的解决方案.但在我的情况下并非如此.

And I also have installed gem 'rmagick' in my gem file, which seems to be the solution for many, with similar problem. But not really in my case.

任何想法可能是错误的?谢谢！

Any ideas what could be wrong ? Thanks!

更新

通过 rails 控制台

via rails console

Image.create :image =>File.open('c:/sites/thrillb/app/assets/images/srf.jpg')

效果不佳.
