这是控制器动作：
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
更新
这是我用于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
这是上传者本身：
# 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
以下是被告模特：

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

这是图片模型：
class Picture < ActiveRecord::Base
acts_as_paranoid
belongs_to :defendant
mount_uploader :image, PictureUploader
end
更新2
我删除了activerecord-session_store宝石，认为这可能是问题，因为错误发生的地方。我还添加了这条线，据说在类似的情况下帮助了其他人（尽管我的直觉最好，因为图像没有被保存，我知道它不仅仅是在重定向之前犯了错误，但我还是尝试了）：
params[:defendant][:picture_attributes][:image].tempfile = nil
即使有这两个修复，我也会遇到同样的错误：
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'

...
答案 0 :(得分：1)
也许这会帮助其他人......我尝试在控制台中上传图像，并意识到我的AWS密钥设置为：
ENV["AWS_ACCESS_KEY_ID"]
Aka my secrets.yml文件看起来像：
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']
因此所有的错误。将我的secrets.yml文件中的更改为：
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'] %>
现在我们都很好。对不起，伙计们，谢谢你！
