Rails簡單導航寶石如何鏈接到除非？

Question

在我的導航配置文件，我有：

sub_nav.item t.id, t.h1.force_encoding("UTF-8"), tag_path(d.slug, t.slug, params.except(:controller, :action).merge(:tag_id => t.id, :page => nil, :kat_id => nil)) 

我不希望它成爲一個鏈接if params[:tag_id] = t.id

Answer 1

if params[:tag_id] == t.id 
    sub_nav.item t.id, t.h1.force_encoding("UTF-8"), tag_path(d.slug, t.slug, params.except(:controller, :action).merge(:tag_id => t.id, :page => nil, :kat_id => nil)) 
else 
    sub_nav.item t.id, t.h1.force_encoding("UTF-8") 
end
