Rails视图不显示内容

我一直盯着这段代码太长，直到3天前，代码工作正常，所以我希望一些新鲜的眼睛会有所帮助。

我的视图应该为一个位置呈现网络主机。然后它将主机拆分为两个选项卡：安全百分比小于99％的主机，以及安全百分比为99％或更高的主机。我的观点只是渲染安全百分比为99％或更高的主机。

network_hosts_controller.rb

＆＃13;
＆＃13; 
class V1::NetworkHostsController < ApplicationController
  before_action :set_location
  before_action :set_network_host, only: [:show]

  def index
    @network_hosts = NetworkHost.all
  end

  def show
  end

  private

  def set_location
    @location = Location.find_by!(identifier: params[:location_id])
  end

  def set_network_host
    @network_host = NetworkHost.find(params[:id])
  end

end
＆＃13;
＆＃13;
＆＃13;

模型/ network_host.rb

＆＃13;
＆＃13; 
class NetworkHost < ActiveRecord::Base
  acts_as_paranoid
  
  belongs_to :location
  has_many :network_host_tests, dependent: :destroy
  has_many :parent_tests, through: :network_host_tests

  validates_presence_of :location, :mac_address, :ip_address
  validates_uniqueness_of :mac_address

  delegate :security_percentage, to: :last_test, allow_nil: true

  def name
    if self.hostname.blank?
      self.ip_address
    else
      "#{self.ip_address} (#{self.hostname})"
    end
  end

  def last_test
    network_host_tests.last
  end

  def test_before_last_test
    network_host_tests.offset(1).last
  end
end
＆＃13;
＆＃13;
＆＃13;

应该呈现安全百分比低于99％的主机的区域是host-list-issues div id，特别是host-data div类，但它现在不是：

host-list-issues div with no content

真正让我失望的是，在使用不同主机的不同登录下，它确实呈现：

host-list-issues div with content

我已经通过Rails控制台运行代码，以确保它实际上也返回了内容：

＆＃13;
＆＃13; 
network_hosts = NetworkHost.all
  
network_hosts = network_hosts.sort_by{ |e| e.security_percentage }
  network_hosts.each do |network_host|
    if network_host.security_percentage < 99
      next unless last_test = network_host.last_test
    end
  end
end
＆＃13;
＆＃13;
＆＃13;

哪些会返回对象（代码段）：

＆＃13;
＆＃13; 
 #<NetworkHost id: 32, location_id: 8, mac_address: "84:38:35:AA:4D:3D", ip_address: "192.168.1.100", hostname: "A Phone", created_at: "2015-03-05 18:00:18", updated_at: "2015-06-06 14:47:04", deleted_at: nil, vendor: nil>,

 #<NetworkHost id: 44, location_id: 8, mac_address: "18:20:32:C1:32:D8", ip_address: "192.168.1.138", hostname: "Thermostat", created_at: "2015-03-05 20:00:27", updated_at: "2015-06-20 15:02:55", deleted_at: nil, vendor: nil>,

＆＃13;
＆＃13;
＆＃13;

因此，在主机出现在某些位置而非其他位置之间，以及当我直接从Rails控制台拉出结果时，我很难过。救命啊！
