我有一个奇怪的问题,不知道如何进一步调试......
如果我用 html 表单上传文件,我会得到:
SystemStackError (stack level too deep):
痕迹是:

分析跟踪,似乎文件已上传并写入数据库:
AREL (0.5ms) UPDATE `accounts` SET `shortcut_icon` = 'aadf09e05f4db4124c62bfb9340aa9bd.jpg', `updated_at` = '2011-07-27 08:28:08' WHERE `accounts`.`id` = 82
但之后它会抛出错误......
在 Rails 控制台中测试载波:
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
工作正常!
好吧,我有一个文件上传@另一个模型,所以载波安装工作正常(类似的上传器)。
测试html表单没有提交文件,效果很好!
so:
- 表单无需文件字段即可工作
- 控制台中的 Carrierwave 文件上传工作
- 不同型号,类似的 Carrierwave 上传器/配置 => 有效!
我怎样才能进一步调试?
谢谢你的帮助!
Rails 3.0.7/ruby-1.9.2-p180/载波 (0.5.3)
编辑:
似乎它只发生在更新操作上。
控制器:
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
