Question

我想使用link_to重定向选择显示页面。但是，当我点击此链接时，它会重定向到根页面。

我尝试了不同的方法，但它总是重定向到索引根目录。

<%= link_to 'Detalhes', selection %>

我也尝试过：

<%= 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

路线，如果需要：

 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

我尝试访问选择时的日志：

Answer 1

正确的实施是：

routes.rb

中的

resources :selections

在你的观点中

link_to 'The text', selection

要验证的事项是：

您在更改route.rb后重新启动了服务器，否则它将无法赶上
在您的视图中，检查链接的HREF是否正确
点击检查您的rails控制台以查看是否没有重定向

链接重定向为Root而不是控制器显示页面
