Rails, turning an image into a link

Question

I want to turn my image into a link. But how? I read different answers but nothing worked.

 <%= link_to image_tag(article.images.first.image.url, :alt => article.title) unless 
      article.images.first.nil? %> 

I used this link to refer to the article by the title.

<%= link_to(article) do %><h2><%= article.title %></h2><% end %>
This works!  the path.     But i want the same path "article" with the image.

Answer 1

This should work:

<%= link_to image_tag(article.images.first.image.url, :alt => article.title) unless 
  article.images.first.nil?, article %>

Answer 2

maybe you can do this ? do a check outside link_to
