【问题描述】：
我在我的 routes.rb 中定义了一个 post 路由，并在 link_to helper 中使用它。当我点击由link_to helper 生成的链接时，我收到一个错误，假设是 get 方法的错误。

我的 routes.rb 文件
Rails.application.routes.draw do
root 'pages#home'
get '/home', to: 'pages#home'
resources :wallpapers do
member do
post 'like'
end
end
end
我的链接地址
<%= link_to like_wallpaper_path(@wallpaper), :method => :post do %>
<i class="glyphicon glyphicon-thumbs-up"></i>
<% end %>
【问题讨论】：
-
错误是？
-
错误是没有路由匹配 [GET] "/wallpapers/2/like"
-
请提供完整的回溯
-
@ArjunSingh 在您的终端中运行
rake routes。它显示带有参数和类型的路由列表。检查请求的路由是否可用。 -
会不会是您的浏览器禁用了 JavaScript？或者您没有通过简单的鼠标左键单击来使用链接？ link_to 关于 :method 选项的文档是：
Supported verbs are :post, :delete, :patch, and :put. Note that if the user has JavaScript disabled, the request will fall back to using GET.
