Question

我正在使用Rails 4，似乎遇到了我在StackOverflow上发现的常见“点路径”错误。但是，它似乎并不是由多元化错误引起的，而且我对Rails太新了解它为什么会发生这种情况。这是路由以及rake routes的输出：

match '/current_board', to: 'board_members#index', via: 'get'
match '/current_board/:id', to: 'board_members#show', via: 'get'

          Prefix  Verb   URI Pattern                       Controller#Action
   board_members  GET    /board_members(.:format)          board_members#index
                  POST   /board_members(.:format)          board_members#create
 new_board_member GET    /board_members/new(.:format)      board_members#new
edit_board_member GET    /board_members/:id/edit(.:format) board_members#edit
     board_member GET    /board_members/:id(.:format)      board_members#show
                  PATCH  /board_members/:id(.:format)      board_members#update
                  PUT    /board_members/:id(.:format)      board_members#update
                  DELETE /board_members/:id(.:format)      board_members#destroy
    current_board GET    /current_board(.:format)          board_members#index
                  GET    /current_board/:id(.:format)      board_members#show

但是，当我执行以下操作时：

<% @board_members[0..5].each do |board_member| %>
    <div class="col-xs-4 col-md-2">
        <a href="<%= current_board_path(board_member) %>">
            <%= image_tag(board_member.photo_url, alt: "Photo of #{board_member.name}", class: 'center-block board-thumbnail img-rounded') %>
            <div class="caption">
                <h4 class="text-center"><%= board_member.name %></h4>
                <p class="text-center"><%= board_member.position %></p>
            </div>
        </a>
    </div>
<% end %>

我最终获得了http://localhost:3000/current_board.1等路径。

首先你应该使用

get '/current_board', to: 'board_members#index', :as => 'current_boards'
get '/current_board/:id', to: 'board_members#show', :as => 'current_board'

这样可以更轻松地解决路线问题。但它太丑了。

并且对于使用“a”，使用带有块的link_to帮助程序

<%= link_to current_board_path( board_member ) do %>
  <%= image_tag(board_member.photo_url, alt: "Photo of #{board_member.name}", class: 'center-block board-thumbnail img-rounded') %>
  <div class="caption">
    <h4 class="text-center"><%= board_member.name %></h4>
    <p class="text-center"><%= board_member.position %></p>
  </div>
<% end %>

它应该有用。试一试。

使用真正的内置路由，更容易扩展和维护：

 resources :current_board, controller: :board_members, only: [:index, :show]

Rails Path Helper生成Dot Route而不是Slash
