Paperclip gem在Rails中崩溃了用户的会话

标签： ruby-on-rails paperclip

我发现了类似的问题，但我的情况有点不同 （Paperclip 3.4.1，Rails 3.2.12，Ruby 1.9.3p392，使用Pow 0.40）

这是我的模特：

class Smoke < ActiveRecord::Base

  [...]

  attr_accessible :latitude, :longitude, :description, :picture

  validates_length_of :description, :minimum => 2, :maximum => 256, :allow_blank => true
  validates_presence_of :latitude, :longitude

  scope :with_picture, where("picture_file_name IS NOT NULL")

  belongs_to :user
  has_many :comments, :dependent => :destroy
  has_many :smoke_reports, :dependent => :destroy

  has_attached_file :picture,
    :default_url => "/assets/missing/:style.jpg",
    :styles => { :thumb => ["55x55", :jpg], :medium => ["500x500", :jpg], :original => ["800x800", :jpg] },
    :storage => :s3,
    :bucket => 'my-bucket-dev',
    :path => "/:class/:style/:id.:extension",
    :url => ":s3_domain_url",
    :s3_credentials => {
      :access_key_id => 'mys3credentials',
      :secret_access_key => 'mys3credentials'
  }

  validates_attachment_size :picture,
    :less_than => 2.megabytes

  validates_attachment_content_type :picture,
    :content_type => /^image\/(jpg|jpeg|pjpeg|png|x-png)$/,
    :message => "Invalid image type. Only jpg/jpeg or png will be accepted."

  [...]

end

在哪里'[...]'我省略了不相关的东西。

当validates_attachment_size或validates_attachment_content_type失败时，会发生一些错误并清除我的所有会话数据（甚至我的登录）。

这就是应用程序日志中出现的所有内容，请检查它：

以下是我上传的文件通过这两种验证方法时日志显示的内容。因此，只有在文件未验证时才会出现此错误。检查：

我很丢失。 有什么帮助吗？

更新

这是我的SmokesController的一部分：

class SmokesController < ApplicationController

  before_filter :deny_unlogged_users, :except => [:new, :show, :count, :refresh_profile]
  before_filter :only_ajax, :only => [:new, :count, :refresh_profile]
  before_filter :only_with_smoke_params, :only => [:create]

  [...]

  def create
    @user = current_user
    @smoke = Smoke.new
    @smoke.latitude = params[:latitude]
    @smoke.longitude = params[:longitude]
    @smoke.picture = params[:picture]
    @smoke.description = params[:description]
    if @smoke.save
      @user.smokes << @smoke
      redirect_to @smoke
    else
      render 'new'
    end
  end

  [...]

end

更新2：

在#rubyonrails@freenode.net上谈论这个问题，每个人都问我关于我的表格。 然后我意识到我正在手动设置authenticity_token，因为你可以看到here。现在form_tag正在自动执行。 （Rails默认做，但我不知道）

无论如何，这是我的表格，仍然是同样的错误，同样的事情：

  <div id="new-smoke-form">
    <%= form_tag '/smokes', :multipart => true, :method => "post" do %>
      <%= hidden_field_tag 'latitude', @smoke.latitude %>
      <%= hidden_field_tag 'longitude', @smoke.longitude %>
      <div id="new-smoke-picture">
        <p>Upload a picture (optional):</p>
        <%= file_field_tag 'picture' %>
        <div class="clear">
        </div>
      </div>
      <div id="new-smoke-description">
        <p>Talk about it:</p>
        <div id="new-smoke-remain" class="new-smoke-remain">256</div>
        <%= text_area_tag 'description', nil, :class => "new-smoke-textarea", :id => "new-smoke-textarea" %>
      </div>
      <%= submit_tag "Create", :class => "new-smoke-button" %>
    <% end %>
  </div>

我生气了。

答案 0 :(得分：4)

我今天遇到过这个问题，看起来这与Pow而不是Paperclip存在问题，与此相关：https://github.com/37signals/pow/issues/125

我只是通过使用Pow作为WEBrick的端口代理而不是作为Rack应用程序来实现它的工作，希望这对你也有帮助。
