I'm trying
<%= link_to image_tag("#{gallery.link_to}"), gallery_path(gallery) unless gallery.thumbnail_id == 0%>
and get the error:
ActionView::TemplateError (undefined method `image_tag' for #<Gallery: 0xb7083be4>) on line #23 of app/views/users/index.rhtml
This is my definition of link_to def link_to unless self.thumbnail_id == 0 picture = Picture.find(self.thumbnail_id) path = picture.public_filename(:big_thumb) return "#{path}" else return "" end end
Any idea about that error?
