Rails 4 link_to更大的静态图像

Question

我的文件存储在app/assets/images/subdirectory/image.png和app/assets/images/subdirectory/image_full.png。

在我的app/views/home.html.erb：

中

<%= link_to (image_tag("subdirectory/image.png"), asset_path("subdirectory/image_full.png")) %>

我也试过了：

<%= link_to (image_tag("subdirectory/image.png"), asset_path("subdirectory/image_full.png", image)) %>
<%= link_to (image_tag("subdirectory/image.png"), image_path("subdirectory/image.png", image)) %>

无法通过文档找到更多内容：http://guides.rubyonrails.org/asset_pipeline.html

但是当我尝试加载视图时，它完全崩溃了我的应用程序！

ANSWER

如果还有一个paren，那么在link_to之后应该没有WHITESPACE：

<%= link_to(image_tag("subdirectory/image.png"), image_path("subdirectory/image_full.png", image)) %>

Answer 1

<%= link_to image_path("subdirectory/image_full.png") do %>
  <%= image_tag "subdirectory/image.png" %>
<% end %>

Answer 2

尝试image_path代替asset_path，如下所示：

<%= link_to(image_tag("subdirectory/image.png"), image_path("subdirectory/image_full.png")) %>
