[WARNING]: when statements should not include jinja2 templating delimiters such as {{ }} or {% %}.

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

task:
  - include: lvm.yml
    when: ansible_devices.{{ raw_disk }}.partitions|length == 0

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

  when: ansible_devices[raw_disk]['partitions']|length == 0

and see if that does the trick.
