使用Rails 5.2.1，
我正在为我的应用添加自定义的可能性，该应用基本上是博客...
该应用程序的着陆页可以自定义，博客所有者可以更改图像，颜色等...
因此，我为每个可以个性化的图像创建了一个自定义控制器，模型以及上载器。 自定义只有一个实例。
所以就本地而言，所有事物都像魅力一样。
Rspec失败，因为我正在登录页面中调用@customization ...
无法在 Article
rspec失败

答案 0 :(得分：1)
实际错误是No route matches [GET] "/images/fallback/default.png"。您正在载波上传器上设置默认路径，但看起来图像丢失。那张照片在哪里？该路线应该在/public/images/fallback/default.png
