Rails图像link_to无法正常工作

Question

这很好用

 <%= link_to "up.png", voteup_path(post_id: post.id, topic_id: post.topic_id), class: "xta"  %>

但不是这个

 <%= link_to image_tag("up.png"), voteup_path(post_id: post.id, topic_id: post.topic_id), class: "xta"  %>

请告诉我如何才能让它发挥作用。

Answer 1

尝试此操作，将image_tag和课程传递给link_to代码

<%=link_to( image_tag("up.png"),voteup_path(post_id: post.id, topic_id: post.topic_id), class: "xta") %>
