Hello,

I’m trying to remove jinja delimiter used in when condition.  
My condition tests whether partition exists on disk drive. I use variable to assign which drive to test  
vars:  
raw\_disk: ‘sdb’

task:

- include: lvm.yml  
when: ansible\_devices.{{ raw\_disk }}.partitions|length == 0

with {{ raw\_disk }} I receive [WARNING]: when statements should not include jinja2 templating delimiters such as {{ }} or {% %}.

What should be the correct condition so the variable can be included ansible facts

The shortcut a.b.c.d notation doesn't let you distinguish between literals  
and variables. Try the more Pythonic

&nbsp;&nbsp;when: ansible\_devices[raw\_disk]['partitions']|length == 0

and see if that does the trick.

Josh, thank you for the hint. Work as expected.
