我无法理解发生了什么。几天前我的生产服务器很好，一切都很好。然后需要进行一些更改（生产数据库重置），之后，我的应用程序的图像上传功能开始响应错误500，但仅在生产中。在开发中，上传发生时没有错误，但生产不能再这样做了，我不知道为什么。
以下是图片上传的 development.log ：

图像是一样的，一切都是一样的。 我正在考虑Rails / tmp的权限，但即使在“sudo chmod 777 / tmp”LOL之后也会出现。
我的nginx error.log也没有告诉它。 我该怎么办？
在哪里寻找线索？
额外信息：我的应用程序在Amazon S3中存储图像（即使在开发中）;它使用Carrierwave;
修改
正如diego.greyrobot所提到的，我使用了救援例外，看起来我找到了一个很大的线索。我还不明白，但我会一直试图弄清楚发生了什么。
检查控制器中的代码......
smokes_controller.rb ：
def create
@user = current_user
@smoke = Smoke.new(params[:smoke])
logger.debug ENV['USER']
begin
if @smoke.save
@user.smokes << @smoke
redirect_to @smoke
else
render 'new'
end
rescue Exception => e
puts e.class
puts e.message
puts e.backtrace
end
