從某些頁面獲取路由錯誤

Question

我有這條路

profile GET /contacts/:id(.:format) {:controller=>"my_devise/contacts", :action=>"profile"}

這是我的controllers / application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery

  before_filter :get_current_user

    def get_current_user
        @current_user = current_user
    end

end

如果我的view / layouts / application.html.erb文件中的此鏈接<%= link_to "Profile", profile_path(@current_user) %> URL http://localhost:3000/contacts/1上的<%= link_to "Profile", profile_path(@current_user) %> ，我沒有錯誤，但是如果我嘗試點擊url http://localhost:3000/contacts ，則會收到以下錯誤

Routing Error

No route matches {:controller=>"my_devise/contacts", :action=>"profile"}

如果我刪除了application.html.erb文件中的鏈接並點擊http://localhost:3000/contacts ，則錯誤消失了。

為什么該鏈接會導致此錯誤？

Answer 1

要回答您的實際問題，這是因為您沒有為此的路線（ /contacts注意沒有ID）。 您的路線是/contacts/:id(.:format)格式是可選的，但id不是。 您還需要將ID設置為可選，或創建其他路由。

Answer 2

路線是這樣的

聯系人GET /contacts(.:format）{：action =>“列表”，：controller =>“ my_devise / contacts”}

在這里，我們還必須提供格式。 如果我們給聯系人，它將引發路由錯誤。 因此，請同時輸入格式。
