Rails 3.2.8 - 路由和link_to_paths

Question

我想重構我的3.0應用到運行3.2.8的另一臺服務器，並且它出現了路由語法可能已經改變了一點？

鑑於這種routes.rb中：

root :to => 'user_sessions#new' 
match 'login' => 'user_sessions#new' 
match 'logout' => 'user_sessions#destroy' 
match 'usermenu' => 'users#menu' 
match 'adminmenu' => 'users#adminmenu' 

這種觀點：

<% if current_user %> 
    <%= link_to "Logout", logout_path %> | 
    <%= link_to "Main Menu", usermenu_path %> | 
    <%= link_to_if (current_user.admin == true, "Admin Menu", adminmenu_path) %> 
<% end %> 

我得到這個錯誤：

ActionView::Template::Error (/home/-/layouts/application.html.erb:19: syntax error, unexpected ',', expecting ')' 
...if (current_user.admin == true, "Admin Menu", adminmenu_path... 

/home/-/layouts/application.html.erb:19: syntax error, unexpected ',', expecting ')' 
...er.admin == true, "Admin Menu", adminmenu_path));@output_bu... 
          ^):

你不能有之間的空間link_to_if和左括號

link_to_if (current_user.admin == true, "Admin Menu", adminmenu_path) 

應該

link_to_if(current_user.admin == true, "Admin Menu", adminmenu_path) 

路線並沒有改變。
