Hi all,
I’d like to extract from a yaml complex dictionary as

node:
host1:

  • { id: ‘1’ }
  • { id: ‘2’ }

all values for ‘id’ for ‘host1’

in order to convert this snipped of code from

id_list: {{ xxx }}

in

id_list: ‘1’ ‘2’

in python I can do the following

node= {‘test1’:[{‘id’:‘1’},{‘id’:‘2’}]}
node
{‘test1’: [{‘id’: ‘1’}, {‘id’: ‘2’}]}
" “.join([”‘%s’"% x[‘id’] for x in node[‘test1’]]) #this is xxx
“‘1’ ‘2’”

but in ansible how can obtain the same?

You can use the map filter, and the join filter.

“{{ node[‘test1’]|map(attribute=‘id’)|join(’ ') }}”

Matt, you saved my day!

With your solution

“‘{{ node[‘test1’] | map(attribute=‘id’) | join(’' '‘) }}’”

I was able to do it,
thanks a lot!
