Question

gem 'paperclip', '~> 4.2'
gem 'aws-s3'
gem 'aws-sdk'

上传图片或任何其他文件。我有这两个模型： employee.rb

class Employee < ActiveRecord::Base
  has_many :attachments, as: :attachable
  accepts_nested_attributes_for :attachments
end

和attachment.rb

class Attachment < ActiveRecord::Base
  belongs_to :attachable, polymorphic: true
  has_attached_file :attach,
                    :storage => :s3,
                    :s3_credentials => '#{Rails.root}/config/s3.yml',
                    :url => ':s3_domain_url',
                    :path => '/contents/:id/:basename.:extension'
  validates_attachment_content_type :attach,:content_type => ['application/msword','application/pdf', 'image/jpg', 'image/jpeg', 'image/png', 'image/gif']
end

和我的employeeS_controller.rb

 def edit
    @employee = Employee.where(id: params[:id]).first
    @employee.attachments.build
  end

  def update
    @employee = Employee.where(id: params[:id]).first
    if @employee.update_attributes(employee_params)
      redirect_to @employee, notice: I18n.t('employee_updated')
    else
      p @employee.errors
      render :action => :edit
    end
  end


  private

  def employee_params
    params.require(:employee).permit(:email, :role, :department_id, :designation_id, :is_active, attachments_attributes: [:attach, :name])
  end

和我的就业/ edit.html.erb

<%= f.fields_for :attachments do |attach|%>
              <%= attach.file_field :attach, :class => 'btn' %>
 <% end %>

现在提交表格的时候我会在我的参数中找到这个

{＆＃34; utf8＆＃34; =＆gt;＆＃34;✓＆＃34;，＆＃34; _method＆＃34; =＆gt;＆＃34; patch＆＃34;，＆＃34; authenticity_token＆＃34; = GT;＆＃34; 4pq1y2qS0AAbO + C6O1Sp0qmKFFXG2KZtB4mvIgvK3CKJ0CI / 5yAYDJArhjsEzu6lSm / LkRfBIJDpSzRZUxp + BQ ==＆＃34 ;, ＆＃34;员工＆＃34; =＆gt; {＆＃34;电子邮件＆＃34; =＆gt;＆＃34; inventory@adroit.com"，＆＃34;角色＆＃34; =＆gt;＆＃34 ;库存＆＃34 ;, ＆＃34; department_id＆＃34; =＆gt;＆＃34; 6＆＃34;，＆＃34; designation_id＆＃34; =＆gt;＆＃34; 3＆＃34;，＆＃34; is_active＆＃34; =＆gt; ;＆＃34; 1＆＃34 ;, ＆＃34; attachments_attributes＆＃34; = GT; {＆＃34; 0＆＃34; = GT; {＆＃34;附＆＃34; = GT;＃， @original_filename =＆＃34; index.jpeg＆＃34;，@ content_type =＆＃34; image / jpeg＆＃34;， @headers =＆＃34; Content-Disposition：form-data; 命名= \＆＃34;雇员[attachments_attributes] [0] [附] \＆＃34 ;; filename = \＆＃34; index.jpeg \＆＃34; \ r \ nConContent-Type：image / jpeg \ r \ n＆＃34;＆gt;}}，＆＃34;操作＆＃34; =＆gt;＆＃34;更新＆＃34;，＆＃34;控制器＆＃34; =＆gt;＆＃34;员工＆＃34;，＆＃34; id＆＃34; =＆gt; ;＆＃34; 3＆＃34;}

但它没有保存在我的数据库中它给我错误NameError （未初始化的常量AWS :: S3 ::错误）：

我在s3.yml中的设置是

development:
  bucket: "test"
  access_key_id: "*************"
  secret_access_key: "*************"

production:
  bucket: "test"
  access_key_id: "*************"
  secret_access_key: "*************"

当我没有bundle show aws-sdk时，我有这个版本的aws-sdk捆绑显示aws-sdk

/home/test/vendor/ruby/2.1.0/gems/aws-sdk-2.0.46

现在请指导遗失的地方我没有得到它。提前谢谢。
