我想使用link_to
重定向選擇顯示頁面。 但是,當我點擊這個鏈接它重定向到根頁面。鏈接重定向爲根目錄而不是控制器顯示頁面
我嘗試了不同的方式,但它總是重定向到索引根。
<%= link_to 'Detalhes', selection %>
我也試過:
<%= link_to 'Detalhes', selection_path(selection) %>
<%= link_to 'Detalhes', selection, :method => :show %>
<%= link_to 'Detalhes', selection, method: :show %>
而且,在routes.rb
:
match '/selections/:id' => 'selections#show', :via => :post
路線,如果需要的是:
selections GET /selections(.:format) selections#index
POST /selections(.:format) selections#create
new_selection GET /selections/new(.:format) selections#new
edit_selection GET /selections/:id/edit(.:format) selections#edit
selection GET /selections/:id(.:format) selections#show
PUT /selections/:id(.:format) selections#update
DELETE /selections/:id(.:format) selections#destroy
我的日誌,當我嘗試訪問選擇:

你不能有這行'match'/ selections /:id'=>'selections#show',:via =>:post'因爲它沒有顯示在你的路線中(或者你沒有包含它)。這條線本身毫無意義,因爲您希望應用程序如何在POST請求上顯示某些內容? –
在這一行中,<%= link_to'單獨',選擇%>'你作爲'選擇'通過了什麼? –
你是對的邁克爾Szyndel,這只是一個絕望的嘗試。 並且在<%= link_to'單元',選擇%>中,選擇是所有選擇索引的列表,其結果是@ selections.each do | selection | –
