出现渲染异常：Jinja 变量 'dict object' 没有属性 'data'

Question

更改 nginx.conf 中的内容时出错

/etc/salt/master.d/reactor.conf

reactor:
  - 'salt/beacon/*/inotify//etc/nginx/nginx.conf':
    - /srv/reactor/web-remediate.sls

/srv/reactor/web-remediate.sls

{% if data['data']['id'] %}
  web_state_run:
    local.state.apply:
      - tgt: {{ data['data']['id'] }}
      - arg:
        - webserver.nginx
{% endif %}

我已将反应器配置文件的条件行从 /srv/reactor/web-remediate 中的 {% if data['data']['id'] %} 修改为 {% if data['id'] %} .sls 现在反应器工作正常。

只是我假设下面一行的数据字典只包含'id'键，所以我跳过了['data']

 [DEBUG   ] Sending event: tag = salt/beacon/minion1.vagrant.net/inotify//etc/nginx/nginx.conf; data = {'path': '/etc/nginx/nginx.conf', '_stamp': '2017-09-23T12:21:17.586647', 'id': 'minion1.vagrant.net', 'change': 'IN_MODIFY'}

修改：

 From:

  {% if data['data']['id'] %}
   web_state_run:
     local.state.apply:
       - tgt: {{ data['data']['id'] }}
       - arg:
         - webserver.nginx
 {% endif %}


 To:

 {% if data['id'] %}
 web_state_run:
   local.state.apply:
     - tgt: {{ data['id'] }}
     - arg:
       - webserver.nginx
 {% endif %}

输出：
