用Jinja2模板提取嵌套字典

1 人不认可

我有这样的代码，有嵌套的字典，我需要把它放在一个Jinja2模板中，但没有任何运气。

from jinja2 import Template
vlans = {"1": {"description": "default", "name": "default", "IP": {"IP1": "10.0.0.1", "IP2": "20.0.0.2"}}}
vlan_template = Template('''
{% for key,value in vlans.items() %}
vlan {{ key }}
 description {{ value.description }}
 name {{ value.name }}
 {% if value == "IP"%}
  {% for subkey,subvalue in value["IP"].items() %}
  ip address {{ subvalue.IP1 }}
  ip address {{ subvalue.IP2 }} secondary
  {% endfor %}
 {% endif %}
{% endfor %}
print(vlan_template.render(vlans = vlans))
我试图得到以下输出结果
vlan 1
 description default
 name default
 ip address 10.0.0.1
 ip address 20.0.0.2 secondary

           我已经设法找到了这个代码
          
          from jinja2 import Template
vlans = {"1": {"description": "default", "name": "default", "IP": {"IP1": "10.0.0.1", "IP2": "20.0.0.2"}}}
vlan_template = Template('''
{%- for key,value in vlans.items() %}
 {%- for k,v in value.items() %}
vlan {{ key }}
 description {{ value.description }}
 name {{ value.name }}
 ip address {{ v.IP1 }}
 ip address {{ v.IP2 }}
 {%- endfor %}
{%- endfor %}
print(vlan_template.render(vlans = vlans))
which gives me 3 times the info but only the 3rd time is correct
vlan 1
 description default
 name default
 ip address 
 ip address 
vlan 1
 description default
 name default
 ip address 
 ip address 
vlan 1
 description default
 name default
 ip address 10.0.0.1
 ip address 20.0.0.2
问题是，我只想打印
vlan 1
 description default
