I tried to use omit with an expression like this:
id: "{{ openstack_networks.id | default(omit) }}"
But it seems that it keeps failing with an exception when openstack_networks
variable is not defined.
What is the correct way to write this jinja2 filter?
I want to omit the parameter in case openstack_networks.id does not exists.
Not super elegant, but 100% working solution to handle keys of possibly undefined parent dicts:
id: "{{ (openstack_networks | default({})).id | default(omit) }}"
This will give you omit
if openstack_networks
is defined but has no id
key or if openstack_networks
is undefined.
