這是控制器動作： 

  def update
    @defendant = Defendant.find(params[:id])
    convert_params

    unless @defendant.update_attributes(sanitized_params)
      flash[:notice] = @defendant.errors.full_messages.to_sentence
    end

    redirect_to edit_defendant_path(@defendant)
  end

  private

    def sanitized_params
      params.require(:defendant).permit(
        :organization_id, :name, :maiden_name, :birthday, 
        :email, :weight, :height, :skin_color,
        :eye_color, :gender, :race, :hair_color,
        :scar_or_tattoo, :spouse_name, :facebook_url, :nickname_or_alias,
        :marital_status, :united_states_citizen, :ssn,
        picture_attributes: [
          :image
        ]
      )
    end

    def convert_params
      params[:defendant][:birthday] = convert_date_string(params[:defendant][:birthday])
    end

UPDATE

這是我用於Carrierwave的初始化程序： 

if Rails.env.test?
  CarrierWave.configure do |config|
    config.storage = :file
  end
else
  CarrierWave.configure do |config|
    config.storage = :fog
    config.fog_credentials = {
      :provider               => 'AWS',    
      :aws_access_key_id      => Rails.application.secrets.aws_access_key_id,    
      :aws_secret_access_key  => Rails.application.secrets.aws_secret_access_key,   
      :region                 => 'us-east-1'
    }
    config.fog_directory  = "myapp-#{Rails.env}"
  end
end

if Rails.env.test?
  CarrierWave.configure do |config|
    config.enable_processing = false
  end

  PictureUploader

  CarrierWave::Uploader::Base.descendants.each do |klass|
    next if klass.anonymous?
    klass.class_eval do
      def cache_dir
        "#{Rails.root}/spec/support/uploads/tmp"
      end

      def store_dir
        "#{Rails.root}/spec/support/uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
      end
    end
  end
end

這是上傳器本身： 

# encoding: utf-8

class PictureUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  # storage :file
  # storage :fog
  # DECLARED IN INITIALIZER

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  def default_url
    # For Rails 3.1+ asset pipeline compatibility:
    ActionController::Base.helpers.asset_path([version_name || "picture", "placeholder.png"].compact.join('_'))

    # "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  end

  # Process files as they are uploaded:
  # process :scale => [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  process resize_to_fit: [500, 500]

  version :thumbnail do
    process resize_to_fill: [50, 50]
  end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  # def extension_white_list
  #   %w(jpg jpeg gif png)
  # end

  # Override the filename of the uploaded files:
  # Avoid using model.id or version_name here, see uploader/store.rb for details.
  # def filename
  #   "something.jpg" if original_filename
  # end

end

這是被告人模型： 

class Defendant < ActiveRecord::Base
  include DateHelper
  paginates_per 10
  acts_as_paranoid
  attr_encrypted :ssn, key: 'mykeygoeshere', encode: true
  normalize_attribute :nickname_or_alias, with: :blank
  normalize_attribute :marital_status, with: :blank
  normalize_attribute :maiden_name, with: :blank
  normalize_attribute :email, with: :blank
  normalize_attribute :weight, with: :blank
  normalize_attribute :height, with: :blank
  normalize_attribute :skin_color, with: :blank
  normalize_attribute :eye_color, with: :blank
  normalize_attribute :race, with: :blank
  normalize_attribute :hair_color, with: :blank
  normalize_attribute :scar_or_tattoo, with: :blank
  normalize_attribute :spouse_name, with: :blank
  normalize_attribute :facebook_url, with: :blank
  normalize_attribute :ssn, with: :blank

  attr_accessor :forward_to_bond_creation

  belongs_to :organization
  has_many :bonds
  has_many :court_dates
  has_many :payments
  has_one :picture
  has_many :phones, as: :phoneable
  has_many :addresses, as: :addressable

  accepts_nested_attributes_for :picture, reject_if: proc { |attributes| attributes[:image].blank? }
  accepts_nested_attributes_for :phones, reject_if: proc { |attributes| attributes.except(:phoneable_id).all?(&:blank?) }
  accepts_nested_attributes_for :addresses, reject_if: proc { |attributes| attributes.except(:addressable_id).all?(&:blank?) }

  validates_presence_of :organization, :name, :birthday, :gender
  validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/i, allow_nil: true
  validates_format_of :ssn, :with => /\A(\d{3}-?\d{2}-?\d{4})\Z/, allow_nil: true
  validates_format_of :facebook_url, :with => /facebook.com/, allow_nil: true

  def behind_with_payments?
    !!(payment_status =~ "behind_with_payments")
  end

  def current_with_payments?
    !!(payment_status =~ "current_with_payments")
  end

  def payment_status
    if bonds.behind_with_payments.any?
      "behind_with_payments"
    else
      "current_with_payments"
    end
  end

  def picture_url
    if picture
      picture.image.url
    else
      ActionController::Base.helpers.asset_path("picture_placeholder.png")
    end
  end

  def thumbnail_url
    if picture
      picture.image.thumbnail.url
    else
      ActionController::Base.helpers.asset_path("thumbnail_placeholder.png")
    end
  end

  def as_json options={}
    options.merge({ id: id, name: name, birthday: format_date(birthday), thumbnail_url: thumbnail_url })
  end
end

這是圖片模型： 

class Picture < ActiveRecord::Base
  acts_as_paranoid

  belongs_to :defendant

  mount_uploader :image, PictureUploader
end

更新2

我刪除了activerecord-session_store gem，以為可能是問題所在，因為這就是發生錯誤的地方。 我還添加了這條線，據說可以在類似情況下幫助其他人（盡管我有最好的直覺，因為沒有保存圖像，所以我知道它不僅在重定向之前犯了錯誤，而且還是嘗試了一下）： 

params[:defendant][:picture_attributes][:image].tempfile = nil

即使使用了這兩個修復程序，我也會遇到相同的錯誤： 

2014-11-25T19:49:39.916837+00:00 app[web.1]: TypeError (can't dump File):
2014-11-25T19:49:39.916842+00:00 app[web.1]:   vendor/bundle/ruby/2.1.0/gems/actionpack-4.1.0/lib/action_dispatch/middleware/cookies.rb:418:in `serialize'
2014-11-25T19:49:39.916839+00:00 app[web.1]:   vendor/bundle/ruby/2.1.0/gems/actionpack-4.1.0/lib/action_dispatch/middleware/cookies.rb:418:in `dump'
...

1 個解決方案

解決方案1

也許這會對其他人有所幫助...我嘗試在控制台中上傳圖像，並且意識到我的AWS密鑰已設置為： 

ENV["AWS_ACCESS_KEY_ID"]

也就是我的secrets.yml文件看起來像： 

production:
  secret_key_base: ENV["SECRET_KEY_BASE"]
  aws_access_key_id: ENV['AWS_ACCESS_KEY_ID']
  aws_secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']

因此，所有的錯誤。 在我的secrets.yml文件中將其更改為： 

production:
  secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>
  aws_access_key_id: <%= ENV['AWS_ACCESS_KEY_ID'] %>
  aws_secret_access_key: <%= ENV['AWS_SECRET_ACCESS_KEY'] %>

現在我們都很好。 抱歉，謝謝你！
