attachment_fu 업데이트시 유효성 검사 실패

Question

나는 프로젝트에서 오랫동안 첨부 파일 _fu를 사용해 왔으며 모든 것이 괜찮 았지만 이제는 프로젝트를 Rails 2.3.3까지 가져 오려고 할 때 나는 나에게 미치는 이상한 버그를 겪고 있습니다. 이 경우 로고 인 첨부 파일은 Create에서 올바르게 유효성을 유지하지만 업데이트시 유효성 검사에 실패하지는 않습니다. 나는 그것을 디버깅했고 그것은 Intial Validate에 실패하지만 컨트롤러에서 나의 구조에 잡힌 예외를 던지지 않는 것 같습니다. 내가 모든 것을 시도한 것 같지만 이것을 알아낼 수는 없습니다.

제어 장치:

  # POST /tournaments
  # POST /tournaments.xml
  def create
    # Build tournament
    @tournament = Tournament.new(params[:tournament].merge(:user_id => current_user.id) )

    # Save the uploaded attachments
    params[:uploads].each do |upload|
      @tournament.documents << Document.new({:uploaded_data => upload[:document]}.merge(:description => upload[:description]))
    end unless params[:uploads].nil?

    # if supplied save an event logo
    @logo = Logo.new({:uploaded_data => params[:logo][:upload_data]}) unless params[:logo].nil? or params[:logo][:upload_data].blank?  
    @tournament.logo = @logo unless @logo.nil?     

    respond_to do |format|
      begin
        Tournament.transaction do    
          @tournament.logo.save! unless @tournament.logo.nil?
          @tournament.save!  
        end
        flash[:notice] = 'Tournament was successfully created.'
        format.html { redirect_to tournament_url(@tournament) }
        format.xml  { head :created, :location => tournament_url(@tournament) }        
      rescue 
          flash[:notice] = 'Errors prevented your Tournament from being saved'
        format.html { render :action => "new" }
        format.xml  { render :xml => @tournament.errors, :status => :unprocessable_entity }
      end
    end
  end

  # PUT /tournaments/1
  # PUT /tournaments/1.xml
  def update
    @tournament = Tournament.find(params[:id])
    @tournament.user_id = session[:orig_user_id]

    respond_to do |format|
      begin
        Tournament.transaction do   
          # Update Logo if necessary
          unless params[:logo][:upload_data].blank?
            @tournament.logo.destroy unless @tournament.logo.nil?
            @tournament.logo = Logo.new({:uploaded_data => params[:logo][:upload_data]}.merge(:user_id => current_user.id)) 
          end   
          # Save any uploaded documents
          params[:uploads].each do |upload|
            @tournament.documents << Document.new({:uploaded_data => upload[:document]}.merge(:description => upload[:description]))
          end unless params[:uploads].nil?   
          # Update Tournamnet Attributes
          @tournament.attributes = params[:tournament]  
          # Save the Tournament
          @tournament.save!         
        end
        flash[:notice] = 'Tournament was successfully updated.' 
        format.html { redirect_to tournament_url(@tournament) }
        format.xml  { head :ok, :location => tournament_url(@tournament) }        
      rescue 
          flash[:notice] = 'Errors prevented your Tournament from being updated' 
        format.html { render :action => "edit" }
        format.xml  { render :xml => @tournament.errors, :status => :unprocessable_entity }
      end
    end
  end  

로고 모델 :

    class Logo < Asset    

  validate_on_create :attachment_valid? 

  has_attachment :content_type => :image, 
    :storage => :file_system, 
    :max_size => 4.megabytes,
    :resize_to => '810x150>',  
    :processor  => :ImageScience,
    :thumbnails => { :thumb => '270x50>'  }  


  def attachment_valid? 
    content_type = attachment_options[:content_type] 
    unless content_type.nil? || content_type.include?(self.content_type) 
      errors.add(:upload_data, " * must be an image file (jpg, gif, or png)")  
    end 
    size = attachment_options[:size] 
    unless size.nil? || size.include?(self.size)               
      errors.add(:upload_data, "* image must be 4MB or less")  
    end   
  end 


  before_thumbnail_saved do |thumbnail|
    record = thumbnail.parent
    thumbnail.user_id = record.user_id 
    thumbnail.listing_id = record.listing_id
  end

end     

나는 다음을 실행하고있다

레일 2.3.3

image_science 1.2.0

Answer 1

a : prever_save 콜백을 사용하여 객체를 테스트 할 수도 있습니다. 유효하지 않은 경우 예외를 제기하십시오.

Answer 2

추가 시도 :

validate_on_update :attachment_valid?
