i have a weired problem and don't now how to debug further...

if i upload an file with my html form i get:

SystemStackError (stack level too deep):

the trace is:

SystemStackError (stack level too deep):

analysing the trace, it seems that the file is uploaded and written to the DB:

 AREL (0.5ms)  UPDATE `accounts` SET `shortcut_icon` = 'aadf09e05f4db4124c62bfb9340aa9bd.jpg', `updated_at` = '2011-07-27 08:28:08' WHERE `accounts`.`id` = 82

but after that it throws the error....

testing carrierwave in the rails console:

ruby-1.9.2-p180> path = "/Users/kalle/Desktop/button.png"
ruby-1.9.2-p180> u = Account.last
ruby-1.9.2-p180> u.logo = File.open(path)
 => #<File:/Users/kalle/Desktop/button.png> 
ruby-1.9.2-p180> u.save!
 => true

works fine!

well, i have a file upload @ another model, so the carrierwave installation works fine (similar uploader).

testing the html form without the file filed, it works fine!

so:

  • Form works without file field
  • carrierwave file upload works in the console
  • different model, similar carrierwave uploader/config => works!

how can i debug further ?

thanks for any help!

Rails 3.0.7/ruby-1.9.2-p180/carrierwave (0.5.3)

EDIT: seems that it happens only on the update action.

controller:

def update
  if current_account.update_attributes(params[:account])
    flash[:notice] = 'Successfully updated account.'
    redirect_to global_settings_path
  else
    render :action => 'edit'
  end
end

我有一个类似的问题。当我调用 photo.url 时，它抛出了“堆栈级别深度错误”。

我的 PhotoUploader 中似乎有以下代码：

  默认网址
    文件名 = self.to_s
    content_type = File.mime_type?(文件名)    
    分机 = {
      '图像/png' => :png,
      '图像/jpg' => :jpg,
      '图像/jpeg' => :jpg,
      '图像/gif' => :gif

    }[内容类型]
    分机 ||= :jpg

    { :id => model.id, :version => version_name, :format => ext }    
  结尾

此代码似乎在carrierwave 0.5.8 中运行良好。我更新到 0.6.2，因为它失败了。

问题是我打电话给self.to_s。正如我在载波代码中发现的那样： to_s 是这样实现的：

  def to_s
    网址 || ''
  结尾

通过将 self.to_s 更改为 self.file 问题解决了

  默认网址
    文件名 = self.file
    # ...其余代码..
  结尾
