在ruby

Question

如果有多个用户具有“所有者”角色，我试图仅允许删除。我想显示一条错误消息，如果它是唯一的所有者，则无法删除用户（具有角色所有者）。这就是表格的样子。

def destroy
  @user = @organization.users
  .active
  .find(params[:id])

  lastOwner = @organization.users
  .active
  .where(role: "owner")
  .where.not(id: @user.id)
  .count
  .zero?

  if lastOwner
    flash[:error] = "There must always be at least one owner, please give another user the role first"
    redirect_to teams_path
    return
  else
    if @user && @user.archive!

      respond_to do |format|
        format.html { redirect_to teams_path }
        format.json { head :no_content }
        format.js   { render :layout => false }
      end
    end
  end
end

这是我的破坏方法。

发生的事情是我尝试重定向但我收到错误

一旦我收到错误，记录不会删除，但错误消息没有闪烁，但页面被重定向。当我刷新页面时，我看到错误消息。请帮助，谢谢！

修改

这是删除的代码

link_to('', team_path(user), method: :delete, data: {confirm: "Are you sure you want to delete this member?"}, :remote => true, class: "btn btn-danger fa fa-trash delete_user")

这些是我的路线

teams GET    /teams(.:format)                                         teams#index
                                         POST   /teams(.:format)                                         teams#create
                                new_team GET    /teams/new(.:format)                                     teams#new
                               edit_team GET    /teams/:id/edit(.:format)                                teams#edit
                                    team PATCH  /teams/:id(.:format)                                     teams#update
                                         PUT    /teams/:id(.:format)                                     teams#update
                                         DELETE /teams/:id(.:format)                                     teams#destroy

Answer 1

尝试在redirect_to teams_path代码块中将redirect_to teams_url更改为respond_to。
