In production (Heroku), I'm getting the following error:

I'm running Rails 3.2.6, including actionpack 3.2.6 which I thought had this fix for this issue: https://github.com/rails/rails/commit/6bb86e1f3f7f9e11ee1c056d8742125173ecbce1

I also tried this: "ActionView::Template::Error ( isn't precompiled)" raised on "image_tag nil"

Basically, as long as one of the images on this page don't exist, it's throwing this error. If I upload the images, it works fine. Any ideas?

Thanks, --Mark

我假设您正在使用 CarrierWave 之类的东西来处理文件上传？您可以在上传器类中指定默认图像处理程序：

https://github.com/jnicklas/carrierwave#providing-a-default-url

class MyUploader < CarrierWave::Uploader::Base
  def default_url
    "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  end
end

这将输出默认图像，而不是尝试访问资产管道中名为“”的不存在文件。
