Rails 不显示我的图像文件。路由错误 [GET]

Question

我写了：

$('.book_cover_here').html("<img src='http://bookworm.az/public" + $(this).data("cover") + "' />");

});

所以，整个URL是正确的：

http://bookworm.az/public/uploads/covers/bookworm-2.png

但它不显示图像文件并打印路由错误 [GET]。我被加到config/application.rb下一行：

config.serve_static_assets = true

但这也无济于事。我该如何解决这个问题？

Answer 1

"<img src='http://bookworm.az/public" + $(this).data("cover") + "' />"

您打开双引号，然后打开单引号，但随后关闭双引号，单引号仍然打开。正确吗？

Answer 2

您是否尝试过从 URL 中删除 /public/ 部分？

启动 Rails 应用程序时，您不必再明确告诉应用程序从 public 文件夹中搜索内容。 Rails 将在运行时默认搜索 public 文件夹中的所有资源。

所以在你的情况下：

('.book_cover_here').html("<img src='http://bookworm.az/" + $(this).data("cover") + "' />");
