如何在不使用Asset Pipeline的情况下在Rails 5中提供静态图像？ [英] How to serve static image in Rails 5 without using Asset Pipeline?

问题描述

我有一个基于网络的应用，后端基于 Rails 5。我正在使用 AngularJS 作为前端。我没有使用资产管道来提供任何静态内容，所有脚本（JS& CSS）都加载在位于 index.html 文件中在公共目录中，我从那里使用angular的 ng-route 来进一步管理该位置。

I have a web based app with the back-end build on Rails 5. I am using AngularJS for the front end. I am not using Asset Pipeline to serve any static content, all my scripts(JS&CSS) are loaded in the index.html file located in the public directory and from there I'm using angular's ng-route to further manage the location.

当我的 HTML 页面之一出现问题时，我需要使用 HTML图片标记包含图片，问题是服务器找不到图像文件。

The problem arises when in one of my HTML page I need to include an image using the HTML image tag, the problem is that the server cannot find the image file.

<img src="assets/images/logo.jpg" style="padding-bottom:20px;" />

我试图将图像保存在 app / assets / images 和 public / assets / images 目录但是在所有实例上我收到路由错误，指出我的rails服务器控制台中找不到路由。

I tried keeping my image both in app/assets/images and public/assets/images directory but on all the instances I get routing error stating no route found in my rails server console.

参考几个堆栈溢出答案我在配置development.rb文件中尝试了这一行：

Referring to several stack overflow answers I tried this line in my config development.rb file :

  config.public_file_server.enabled = true

但它不起作用。那么如何在不使用Rails Assetpipeline的情况下提供图像？

But it didn't work. So how can I have served images without using the Rails Assetpipeline?

推荐答案

要在不使用资产管道的情况下提供图像，请放置图像在公共目录中。

To serve images without using the asset pipeline, put your images in the public directory.

your_app / public / images / logo的图片。在您的视图中使用< img src =/ images / logo.jpg 引用jpg 。

An image at your_app/public/images/logo.jpg is referenced using <img src="/images/logo.jpg in your view.

Rails还为此提供了一个帮助方法，它生成相同的代码，但提供了一些额外的Rails功能：\

Rails also provides a helper method for this, which generates the same code but provides some additional Rails features:\

<%= image_tag('/images/logo.jpg') %>

再次，你省略了 public 部分路径。此外，我建议不要在 public 中设置一个名为 assets - 它会被资产管道覆盖。它也会让你感到困惑。我会把目录名改为别的。

Again, you omit the public part of the path. Furthermore, I'd advise against having a directory in public called assets - that will get overridden by the asset pipeline. It'll also confuse you. I'd change that directory name to something else.
