Rails会忽略ActionView :: Template :: Error丢失资产 [英] Rails ignore ActionView::Template::Error for missing assets

问题描述

ActionView::Template::Error (leagues/lal11.png isn't precompiled):

添加新联赛但未预编译对应的图像时，在我的应用中会发生此类错误.

我理解为什么会这样；资产清单缺少相关路径，因此Rails无法为其确定摘要.但是，由于缺少简单的映像而杀死整个应用程序是愚蠢的.有没有办法捕获这个特定的异常?

解决方案

我完全同意您的看法，由于缺少图像而引发错误...我认为资产管道是Rails中最糟糕的代码！/p>

我对如何解决该问题有一些想法:

您可以启用实时编译config.assets.compile = true

您可以在使用的助手(image_tag或其他工具)中捕获该错误，并渲染默认图像.

如果错误未遍及您的应用，则可以在控制器中使用rescue_from.

ActionView::Template::Error (leagues/lal11.png isn't precompiled):

Errors of this sort happen in my app when a new league is added but the corresponding image hasn't been precompiled.

I understand why this is happening; the asset manifest is missing the relevant path and so rails can't determine the digest for it. However, killing the whole app because of a simple missing image is stupid. Is there a way to catch this specific exception?

解决方案

i could not agree more with you, raising errors for missing images... i think the asset-pipeline is the most crappy piece of code in rails!

i have some ideas on how you could tackle the problem:

you could enable live compilation config.assets.compile = true

you could catch that error in the helper you are using (image_tag or whatever) and render a default image.

you could use rescue_from in your controller if the error is not allover your app.
