template 從dict 中取值

[changchichung]

我有兩個 dict 內容長這樣
teams.yml

{
"teams": [{"gid": 10125,"location": ["hq"],"name": "aa","users": ["chenhu","chouf"]},
{"gid": 10126,"location": ["hq"],"name": "ac","users": ["guoj","yangc"]}]

}

users.yml
{
"users": [{"name": "changc","uid": 20000},{"name": "changb","uid": 20001}]
}

我想要取出 teams 裡面的users
所以我簡單的先用個for loop 來跑跑看

{% for j in teams %}   
{{ j.users }}
{% endfor %}         

然後就會報錯

AnsibleUndefinedVariable: 'dict object' has no attribute 'users'

可是 users 不就在那邊嗎？為什麼抓不到啊？
不只是 users ，只要是值有用 [ ] 包起來的，像是 teams 的location ，我也是抓不到 ，但是 teams.gid 卻可以... ???
