Ruby on rails 是否将注释结果作为未定义的方法“注释路径”删除？

当我试图删除注释时，注释并没有从数据库中删除，而且还有一个错误，未定义方法“comment_path”

_comment.html.erb

microposts_控制器.rb

routes.rb

或

您的注释嵌套在MicroPost的范围内

要使其工作，您必须在锚定标记中提供一个微孔

例如：

---

由于您有嵌套资源，因此必须执行以下操作：

1.在控制器中：

# DELETE /microposts/:micropost_id/comments/1
def destroy
  #1st you retrieve the micropost thanks to params[:micropost_id]
  micropost = Micropost.find(params[:micropost_id])
  #2nd you retrieve the comment thanks to params[:id]
  @comment = micropost.comments.find(params[:id])
  @comment.destroy

  flash[:success] = "Micropost deleted"
  redirect_to request.referrer || root_url
end

2.在您看来，替换

link_to "Delete Comment", [comment.micropost, comment], method: :delete

# OR

link_to "Delete Comment", microposts_comment_path(comment.micropost, comment), method: :delete

# DELETE /microposts/:micropost_id/comments/1

<%= link_to "delete", [comment.micropost, comment], method: :delete %>
