Rails link_to銷毀嵌套資源？

Question

我有一個嵌套的資源附件，我想創建一個link_to來銷毀/刪除附件。 這就是我所擁有的，但它是作為GET而不是PUT發布的：

<%= link_to "Delete Attachment", project_thread_attachment_path(@attachment.thread.project.id, @attachment.thread.id, @attachment.id), :confirm => "Are you sure you want to delete this attachment?", :method => :delete, :action => "destroy" %>

想法？ 謝謝！

Answer 1

嘗試

link_to "Delete Attachment", [@attachment.thread.project,@attachment.thread,@attachment], :confirm => "Are you sure?", :method => :delete

它有用嗎？

Answer 2

您應該能夠自己使用以下內容（刪除：action =>'destroy'部分）。 此外，請求應該是DELETE請求，而不是PUT請求：

<%= link_to "Delete Attachment", project_thread_attachment_path(@attachment.thread.project.id, @attachment.thread.id, @attachment.id), :confirm => "Are you sure you want to delete this attachment?", :method => :delete %>
