What to do? 该怎么办？

Answer 1

<%= link_to image_tag('town.png'), 'index' %>

加上一些括号

Answer 2

You need some () 您需要一些()

<%= link_to image_tag("town.png"), pages_path %>

Also, you need to use image_tag 另外，您需要使用image_tag

Answer 3

<%= link_to image_tag("town.png"), image_path %>

如果您想让它单独转到带有图像的另一页

Answer 4

Yeah some brackets would perhaps help. 是的，有些括号也许会有所帮助。 Try something like this: 尝试这样的事情：

<%= link_to(image_tag("town.png", :alt => 'Town Image'), index_url) %>
