回形針寶石崩潰在Rails的用戶的會話

Question

我發現了類似的問題，但我的是有點不同。
（回形針3.4.1，Rails的3.2.12，紅寶石1.9.3p392，使用戰俘0.40）

這裏是我的模型：

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 

如果 '[...]' 我省略無關東西。

當validates_attachment_size或validates_attachment_content_type失敗時，會發生一些錯誤，並清除所有會話數據（甚至是我的登錄名）。

這一切是什麼出現在應用程序日誌，檢查：

Started POST "/smokes" for 127.0.0.1 at 2013-05-14 23:48:38 -0300 
Processing by SmokesController#create as HTML 
WARNING: Can't verify CSRF token authenticity 
Redirected to http://weedmap.dev/login 
Filter chain halted as :deny_unlogged_users rendered or redirected 
Completed 302 Found in 9ms (ActiveRecord: 2.4ms) 

而且遵循的是什麼日誌顯示，當我上傳的文件通槽這兩種驗證方法。所以這個錯誤只出現在文件沒有驗證的時候。檢查：

我很迷路。 有什麼幫助嗎？

UPDATE：

這裏是我的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大家講到這裏問我我的形式。 然後我意識到我手動設置了authenticity_token，你可以看到here。現在form_tag自動執行。 （Rails的做在默認情況下，但我不知道）

不管怎麼說，這是我的形式，還是一樣的錯誤，同樣的事情：

<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> 

我惹毛了。

我今天碰到這個問題，它看起來像它與力量屬性而非回形針的問題，與此相關的：https://github.com/37signals/pow/issues/125

我只設法得到它的工作通過使用戰俘作爲港口代理的WEBrick而不是作爲一個機架應用程序，希望這也可以幫助你。
