但现在我搬到了一个新的项目,我试图复制我用第一个步骤使图像上传工作.但我不能,这让我发疯！请帮我解决这个问题……我已经失去了几个小时. ： – /

这就是发生的事情：
我创建了一个选择照片的活动,我认为上传甚至没有开始(它太快了！).没有错误被调用,我活动的“photo”属性是/photos/original/missing.png

这是我的模型文件：

class Activity < ActiveRecord::Base  has_many :infos,:dependent => :destroy  has_many :links,:dependent => :destroy  has_many :events,:dependent => :destroy  accepts_nested_attributes_for :infos  has_attached_file :photo,:styles =>{      :thumb  => "80x60#",:medium => "160x120#",:large => "320x240#",:home => "320x370#"    },:storage => :s3,:s3_credentials => "#{RAILS_ROOT}/config/s3.yml",:path => ":attachment/activitIEs/:ID/:style.:extension",:bucket => 'andrea'end

我的Gemfile：

source 'http://rubygems.org'gem 'rails','3.0.5'gem "paperclip","~> 2.3"gem 'aws-s3'# Bundle edge Rails instead:# gem 'rails',:git => 'git://github.com/rails/rails.git'gem 'sqlite3'# Use unicorn as the web server# gem 'unicorn'# Deploy with CAPIstrano# gem 'cAPIstrano'# To use deBUGger (ruby-deBUG for Ruby 1.8.7+,ruby-deBUG19 for Ruby 1.9.2+)# gem 'ruby-deBUG'# gem 'ruby-deBUG19',:require => 'ruby-deBUG'# Bundle the extra gems:# gem 'bj'# gem 'nokogiri'# gem 'sqlite3-ruby',:require => 'sqlite3'# gem 'aws-s3',:require => 'aws/s3'# Bundle gems for the local environment. Make sure to# put test-only gems in this group so their generators# and rake tasks are available in development mode:# group :development,:test do#   gem 'webrat'# end

和我的s3.yml(用完整的键代替“……”)：

development:  bucket: andrea  access_key_ID: AKIAII...  secret_access_key: vM977oy6W2TIbarCG9...test:  bucket: andrea  access_key_ID: AKIAII...  secret_access_key: vM977oy6W2TIbarCG9...production:  bucket: andrea  access_key_ID: AKIAII...  secret_access_key: vM977oy6W2TIbarCG9...

这是日志：

如果您需要更多信息,请告诉我！

哦,我已经尝试过heroku重启,但没有任何改变.

解决方法 哦耶！！

最后我抓住了它：我需要更改我的_form.HTML.erb

<%= form_for @activity do |f| %>...<% end %>

至

<%= form_for @activity,:HTML => { :multipart => true } do |f| %>...<% end %>
