Initially, this code:
最初,这段代码:
<%= image_tag(thumbnail(drawing.image_url), class: "drawing")%>
which resulted in:
结果导致:
<img class="drawing" src="http://res.cloudinary.com/brandonliu/image/upload/t_thumb_large/v1430498900/00001.jpg" alt="00001">
worked just fine, but as soon as I switched it to a link_to:
工作得很好,但一旦我将其切换到link_to:
<%= link_to image_tag(thumbnail(drawing.image_url), class: "drawing"), drawing %>
the image stopped displaying. The image in fact disappears anytime I surround it with a hyperlink tag, does anyone know why?
图像停止显示。事实上,当我用超链接标签环绕它时,图像就会消失,有谁知道为什么?
EDIT: I don't think the problem is with the rails syntax, because simply doing
编辑:我不认为问题是与rails语法,因为干脆做
<a><%= image_tag(thumbnail(drawing.image_url), class: "drawing")%></a>
still does not allow the image to display
仍然不允许显示图像
2 个解决方案
#1
Try pass a block with image_tag to the link_to helper:
尝试将带有image_tag的块传递给link_to帮助器:
<%= link_to some_path_here do %>
<%= image_tag(thumbnail(drawing.image_url), class: "drawing") %>
<% end %>
From documentation:
You can use a block as well if your link target is hard to fit into the name parameter.
如果您的链接目标很难适合name参数,也可以使用块。
#2
image_tag renders the string
image_tag呈现字符串
<img src="...">
which is the image tag. To make a link, you need the path to the image, not a rendering of a tag.
这是图片标签。要创建链接,您需要图像的路径,而不是标记的呈现。
Try this
<%= link_to image_path(thumbnail(drawing.image_url)) %>
