如何为此路线制作路径助手?
resources :news
match 'news/:year/:month/:day' => 'news#show',
:constraints => { :year => /\d{4}/, :month => /\d{2}/, :day => /\d{2}/ },
:as => 'newsdate'
我尝试了很多方法,但它不起作用:
link_to news.created_at.strftime '%d.%m.%Y ', newsdate_path(:year => '2011', :month => '11', :day => '11')
我通过GET http://localhost:3000/news获取此行的应用错误:
ArgumentError in News#index
Showing /home/foxweb/work/dev/app/views/news/index.html.slim where line #6 raised:
wrong number of arguments (2 for 1)
如何正确使用?
P.S。 http://localhost:3000/news/2011/11/11工作正常。
答案 0 :(得分:5)
哦,这是常见的错误。您需要在大括号中使用strftime
个参数。
link_to news.created_at.strftime('%d.%m.%Y'), newsdate_path(:year => '2011', :month => '11', :day => '11')
这就是全部!
