我对Jinja2很新，我想知道如何实现这个目标。
说我有以下---
servers:
192.168.0.1:
names:
- foo.example.com
- foo
exports:
data:
foo1: /disks/foo1
foo2: /disks/foo2
192.168.0.2:
...
：
/data/foo1我想创建符号链接/disks/foo1到/data/foo2和/disks/foo2到foo，但只能在file status=link with_items=...服务器上创建;在其他服务器上，为各自的导出创建符号链接。所以我认为[
{ 'mount': mount, 'export': export }
for ip, server in servers.iteritems()
if ansible_hostname in server['names']
and 'exports' in server
and 'data' in server['exports']
for mount, export in server['exports']['data'].iteritems()'
]
是正确的做法。在Python中，我可以使用以下逻辑获取我需要的数组：
{{ servers | select('ansible_hostname in self.names') | ... }}
我不知道如何在Jinja2中这样做。我想做一些像
这样的事情servers但这不起作用。我需要为这个逻辑创建一个插件吗？或者我的方法是错的，我应该重新考虑我的MariaDB []> select * from plc_data order by data_ora desc limit 50;
