Question

以下循环显示与特定项目关联的每个评论，并允许评论所有者（用户）编辑或删除评论。这样就可以了。

现在，我希望管理员能够删除评论。唯一的问题是，当我单击“删除...”时，与特定项目相关的所有注释都会被删除，而不仅仅是该注释。

有什么解决方法吗？

<% @comments.each do |comment| %>
  <% if current_user == comment.user %>
    <%= link_to "Delete", destroy_item_comment_path(comment.item_id, comment.id),
                method: :delete, data: { confirm: I18n.t("comment_delete_alert")}, :class=>"glyphicon glyphicon-trash" %>     
  <% elsif current_admin %>
    <%= link_to "Delete", admin_destroy_item_comment_path(comment.item_id, comment.id),
                method: :delete, data: { confirm: I18n.t("comment_delete_alert")}, :class=>"glyphicon glyphicon-trash" %>
  <% end %>
<% end %>

控制器方法：

before_action :find_comment, only: [:destroy]

def destroy
  @comment.destroy
  redirect_back(fallback_location: root_path)
  flash[:notice] = "Comment has been deleted"
end

def find_comment
  @comment = @item.comments.find(params[:id])
end

以管理员身份删除评论时服务器记录

 Comment Load (0.9ms)  SELECT "comments".* FROM "comments" WHERE "comments"."user_id" = $1  [["user_id", 213]]
 (0.2ms)  BEGIN
  SQL (0.4ms)  DELETE FROM "comments" WHERE "comments"."id" = $1  [["id", 14]]
  SQL (0.4ms)  DELETE FROM "comments" WHERE "comments"."id" = $1  [["id", 15]]
  SQL (0.3ms)  DELETE FROM "comments" WHERE "comments"."id" = $1  [["id", 16]]
   (1.2ms)  COMMIT

我的直觉是您的路由配置不正确。您可以点击

rails routes

检查admin_delete_comment_path配置。

尝试更改

admin_destroy_item_comment_path(comment.item_id,comment.id)

收件人：

destroy_item_comment_path(commend.item_id, comment.id)

Rails循环并以管理员身份删除对象
