Rails路由错误（未定义的局部变量或方法“ micropost_comment”）

Question

我不太清楚为什么在StaticPages＃home中的NameError。 这是我来自views/comments/_comment.html.erb代码

<% if current_user?(comment.user) %>

   <%= link_to 'Destroy', micropost_comment, method: :delete, data: { confirm: 'Are you sure?' } %>

<% end %>

这是我的路线

 micropost_comment GET    /microposts/:micropost_id/comments/:id(.:format)      comments#show
                       PATCH  /microposts/:micropost_id/comments/:id(.:format)      comments#update
                       PUT    /microposts/:micropost_id/comments/:id(.:format)      comments#update
                       DELETE /microposts/:micropost_id/comments/:id(.:format)      comments#destroy

有人可以解释如何解决此错误

undefined local variable or method `micropost_comment'

先感谢您

Answer 1

link_to的第二个参数是路径

micropost_comment不是路径，应将其替换为micropost_comment_path

对于您的路线，还应添加以下参数：

<%= link_to 'Destroy', micropost_comment_path(micropost_id:comment.micropost_id, id:comment.id), method: :delete, data: { confirm: 'Are you sure?' } %>

我认为您虽然不需要嵌套路由，但这是另一个问题
