上传图像回形针时获取错误heroku

时间：2014-06-29 07:19:14

标签： ruby-on-rails heroku

我将 Paperclip gem安装到我的rails应用中，这样我就可以让用户上传图片了。一切似乎在当地都很好。然后我通过git push heroku master命令行提示符推送到Heroku，然后继续在线与我的应用程序进行交互。当我尝试上传图片然后单击“提交”按钮时，会显示一条错误消息。

class Pin < ActiveRecord::Base
    belongs_to :user
    has_attached_file :image, :styles => { :medium => "300x300>", :thumb => "100x100>" }
    validates_attachment :image, content_type: { content_type: ["image/jpg", "image/jpeg", "image/png", "image/gif"] }
end

db / migrate add_attached_image_to_pins.rb 

class AddAttachmentImageToPins < ActiveRecord::Migration
  def self.up
    change_table :pins do |t|
      t.attachment :image

    end
  end

  def self.down
    drop_attached_file :pins, :image


  end
end

最后是 Gemfile 

source 'https://rubygems.org'
gem 'rails', '4.1.1'
gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'bootstrap-sass'
gem 'devise', '~> 3.2.4'
gem 'paperclip', github: 'thoughtbot/paperclip'
gem 'aws-sdk', '~> 1.45.0'


group :development, :test do
     gem 'sqlite3'
end

group :production do
     gem 'pg'
     gem 'rails_12factor'
end

gem 'sdoc', '~> 0.4.0',          group: :doc
gem 'spring',        group: :development

production.rb 

Rails.application.configure do

  config.cache_classes = true

  config.eager_load = true

  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  config.serve_static_assets = false

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier
  # config.assets.css_compressor = :sass

  # Do not fallback to assets pipeline if a precompiled asset is missed.
  config.assets.compile = false

  # Generate digests for assets URLs.
  config.assets.digest = true

  # Version of your assets, change this if you want to expire all your assets.
  config.assets.version = '1.0'


  # Set to :debug to see everything in the log.
  config.log_level = :info


  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners.
  config.active_support.deprecation = :notify


  # Use default logging formatter so that PID and timestamp are not suppressed.
  config.log_formatter = ::Logger::Formatter.new

  # Do not dump schema after migrations.
  config.active_record.dump_schema_after_migration = false

  #required for Heroku
  #Note to set this to your actual host
  config.action_mailer.default_url_options = { host: 'http://omr-photoshare.herokuapp.com/' }
# sets paperclip to upload image to aws
  config.paperclip_defaults = {
    :storage => :s3,
    :s3_credentials => {
      :bucket => ENV['S3_BUCKET_NAME'],
      :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
      :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
  }

end

到目前为止，一切似乎都有效，直到我开始通过 Heroku 在线与我的应用进行互动。

实际错误在这里：

Paperclip::Error (Pin model missing required attr_accessor for 'image_file_name')

您需要将类似Paperclip的相关列添加到Pin模型中：

rails generate paperclip Pin image

heroku run rake db:migrate

或创建迁移文件，例如：

class AddAvatarColumnsToUsers < ActiveRecord::Migration
  def self.up
    add_attachment :users, :avatar
  end

  def self.down
    remove_attachment :users, :avatar
  end
end

You Pin模型还应指定：

Class Pin < ActiveRecord::Base
  has_attached_file :image

<强> DB

这是您的错误：

Paperclip::Error (Pin model missing required attr_accessor for 'image_file_name'):

这通常是因为您未在has_attached_file模型中加入paperclip帮助，或者您尚未执行Paperclip migration

如果它在开发中有效，则可能意味着您没有在Heroku上设置db - 可以使用以下方法修复：

$ heroku run rake db:migrate
