路由错误没有路由匹配 [POST] "/resumes/58"

Question

我正在使用带有 sqlite3 数据库的 Rails 4.2.6。我想将数据库中的数据打印到可读的文件中。但是当我单击“显示”按钮时，即使我没有将显示的路由设置为 POST，它也会给我这个错误。

这是正在使用的东西：

index.html.erb：

<% if !flash[:notice].blank?%>
   <div class="alert alert-info">
    <%= flash[:notice]%>

   </div>
<%end%>
<br />

<%= link_to "New File", new_resume_path, class: "btn btn-primary"%>
<br />
<br />

<table class="table table-bordered table-striped">
    <thead>
        <tr>
            <th>Name</th>
            <th>Download Link</th>
            <th></th>
        </tr>   
    </thead>
    <tbody>
        <% @resumes.each do|resume| %>
        <tr>
            <td><%= resume.name%></td>
            <td><%= link_to "Download Resume", resume.attachment_url %></td>
            <td><%= button_to "Delete", resume, method: :delete, class: "btn btn-danger", confirm: "Are you sure to delete #{resume.name}?" %></td>
            <td><%= button_to "Show", resume, method: :show, class: "btn btn-primary"%></td>        
        </tr>

      <% end %>
    </tbody>

</table>

routes.rb:

Rails.application.routes.draw do


   resources :resumes 
   root "resumes#index"

  get 'resumes/index'

  get 'resumes/new'

  get 'resumes/create'

  get 'resumes/destroy'

  get 'resumes/show'
end

rake 路线：

         Prefix Verb   URI Pattern                 Controller#Action
        resumes GET    /resumes(.:format)          resumes#index
                POST   /resumes(.:format)          resumes#create
     new_resume GET    /resumes/new(.:format)      resumes#new
    edit_resume GET    /resumes/:id/edit(.:format) resumes#edit
         resume GET    /resumes/:id(.:format)      resumes#show
                PATCH  /resumes/:id(.:format)      resumes#update
                PUT    /resumes/:id(.:format)      resumes#update
                DELETE /resumes/:id(.:format)      resumes#destroy
           root GET    /                           resumes#index
  resumes_index GET    /resumes/index(.:format)    resumes#index
    resumes_new GET    /resumes/new(.:format)      resumes#new
 resumes_create GET    /resumes/create(.:format)   resumes#create
resumes_destroy GET    /resumes/destroy(.:format)  resumes#destroy
   resumes_show GET    /resumes/show(.:format)     resumes#show

如果还需要什么，请告诉我。

尝试更新显示按钮语法行：

<td><%= button_to "Show", url_for(controller: 'resumes', action: 'show', id: resume.id), method: :get, class: "btn btn-primary"%></td>
