在同一个form里面包括一个主题topic模型和一个附件上传框，奇怪的是上传的文件只要不是图片格式就可以正常工作，然而上传图片时总提示相关联的topic_id是null，导致上传失败！
相关代码：
topic.rb 
class Topic < ActiveRecord::Base
 GENERIC_ANALYSIS_REGEX = /([a-zA-Z]|[\xc0-\xdf][\x80-\xbf])+|[0-9]+|[\xe0-\xef][\x80-\xbf][\x80-\xbf]/
 GENERIC_ANALYZER = Ferret::Analysis::RegExpAnalyzer.new(GENERIC_ANALYSIS_REGEX, true) 
  acts_as_ferret({:fields => [:title,:content] }, { :analyzer => GENERIC_ANALYZER })
  belongs_to :forum, :counter_cache=>true   
  belongs_to :user   
  has_one :attachment
  validates_length_of :title, :minimum =>4, :message=>'主题的标题应不少于4个字符'
  validates_length_of :title, :maximum =>200, :message=>'主题的标题应不多于200个字符'
  validates_length_of :content, :minimum =>20, :message=>'主题的内容应不少于20个字符'  
  def self.per_page
        10
      end 
 
end


attachment.rb: 
class Attachment < ActiveRecord::Base
  belongs_to :topic   
  has_attachment  :storage => :file_system,   
                  :max_size => 1.megabytes,  
                  :thumbnails => { :thumb => '80x80>', :tiny => '40x40>' },  
                  :processor => :Rmagick    
 
end


topic.rhtml:

          redirect_to( :action => 'board',:id=>@forum.id)
       end

windows xp平台，rails 1.2.3，rmagic和attachment-fu的安装应该没有问题。

问题已经解决！
换到生产模式就没有问题了。

生产模式下也不行了，只要附件是图片就出错，说topic_id为null，发其他类型的附件没有问题，程序没动，昨天还正常呢，今天又不行了。

错误代码来了，今天试了一下在attachemnt.rb里面把 :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }注释掉就正常了，奇怪！
下面是没有注释掉时的错误提示：谢谢！

Model Attachment 要配置上传文件类型,如果不配置的话他会认出为".jpg .png ..."这些是图片文件而去裁截了,加上上传文件类型试试?

把 :thumbnails => { :thumb => [50, 50], :geometry => 'x50' }注释掉就正常了，奇怪！


这个可能是问题的关键，rmagic的原因吧，上传图片比较麻烦，我做很多这样的例子，没有出现这个问题，还可能跟其他模块冲突的过，比如topic_id为空你查查原因。。。。

找不到问题的根源，但注释掉就没有问题，不管是生产模式还是开发模式。我觉得也是rmagic的原因，但不知道问题出在哪里。在ubuntu平台下面也一样的情况。
开启这条语句，附件是rar等类型也没有问题。
先这么用着，反正目前也不需要缩略图功能。
