Hello Everyone,

I have a playbook

- name: Test  
uri:  
url: [https://192.168.1.1](https://192.168.1.1)  
method: POST  
body:  
“IPADDRESS={{ item.address }}”  
body\_format: “form-urlencoded”  
when: item.device\_type.model == “2921” or  
item.device\_type.model == “3931”

But this way list is going very big.  
Now I want to create some sort of dictionary and put the name of that to use with when like below:  
vars:

- ciscorouters:
- 2921
- 3931

when: item.device\_type.model == {{ ciscorouters }}

Please let me know the procedure.

Thanks in advance.

1. You can't use {{ }} in when conditions. The condition is already virtually wrapped in {{ }}

2. Try the following:

&nbsp;&nbsp;&nbsp;when: item.device\_type.model in ciscorouters
