Rails link_to销毁嵌套资源？

Question

我有一个嵌套的资源附件，我想创建一个link_to来销毁/删除附件。 这就是我所拥有的，但它是作为GET而不是PUT发布的：

<%= 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？ 谢谢！

Answer 1

尝试

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

它有用吗？

Answer 2

您应该能够自己使用以下内容（删除：action =>'destroy'部分）。 此外，请求应该是DELETE请求，而不是PUT请求：

<%= 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 %>
