我如何编写纯HTML，如< img> ERB中的标签？ [英] How can I write pure HTML like <img> tag in ERB?

问题描述

我想用下面的代码替换<％= link_to image_tag（picture.png）：< img src = /path/picture.png/> 在file.html.erb中

但是当我这样做时，错误，但没有图片显示在页面上。

解决方案

所以，这里是我的回答：

默认情况下，rails将从 public 文件夹中提供所有资产。

您可以将图像放入资产/图像文件夹中，并将其渲染为资产管道。

但是，如果您想使用本地

 < img src =/ path / picture.png/> 
  

就像你在你的问题中提出的那样，那么你应该明白你在<$将相对于您的应用程序的 public 文件夹执行c $ c> src （src =/ path / picture.png）。 / p>

为了完成上述工作， picture.png 不会被放在 app / assets / images / picture.png ，但应放置在 public / path / picture.png 。

按照惯例，您需要将图片放入：

  public / images / picture.png 
  

因此，您应该使用 img 标签在您的视图中，如下所示：

 < img src =/ images / picture.png/> 
  

这对于您的问题可以正常工作。

I want to replace <%= link_to image_tag ("picture.png") with something like this: <img src="/path/picture.png" /> in a file.html.erb

But when I do this, and it works without any error, but no picture shows up on the page.

解决方案

So, here is my answer for you:

By default, rails will be serving all your assets from inside the public folder.

You are able to put images in the assets/images folder and render those because of the assets pipeline.

However, if you want to use the native

<img src="/path/picture.png" />

like you asked in your question, then you should understand that the path you are specifying in your src(src="/path/picture.png") will be taken relative to the public folder of your application.

To make the above work then, picture.png will not be placed in app/assets/images/picture.png, but should be placed in public/path/picture.png.

By convention though, you will want to place the picture in:

public/images/picture.png

So, you should then use the img tag in your view as follow:

<img src="/images/picture.png" />

This will work fine for the purpose of your question.
