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。

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

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

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：
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：
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;
＆＃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
哪些会返回对象（代码段）：
＆＃13;
＆＃13;
＆＃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: 56, location_id: 8, mac_address: "28:0D:FC:E3:5C:43", ip_address: "192.168.1.129", hostname: nil, created_at: "2015-05-21 16:03:19", updated_at: "2015-05-21 16:03:19", deleted_at: nil, vendor: nil>,
#<NetworkHost id: 52, location_id: 10, mac_address: "64:76:BA:9D:11:87", ip_address: "10.10.10.102", hostname: "Razor", created_at: "2015-04-09 15:02:41", updated_at: "2015-06-07 14:55:45", deleted_at: nil, vendor: nil>,
#<NetworkHost id: 41, location_id: 8, mac_address: "54:9F:13:2A:28:16", ip_address: "192.168.1.132", hostname: "Another Phone", created_at: "2015-03-05 18:00:18", updated_at: "2015-06-05 15:29:33", 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>,
#<NetworkHost id: 58, location_id: 3, mac_address: "B8:27:EB:C1:43:42", ip_address: "10.10.10.133", hostname: nil, created_at: "2015-06-02 00:12:19", updated_at: "2015-06-02 00:12:19", deleted_at: nil, vendor: nil>
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！
