Is there a better way to check if var and var.var both were defined in Ansible playbook? -


i have playbook need give other people want deploy os it. specify variables (set of variables limited, of course) in group/host_vars , might not specify of them. so, example, have set of vars:

var1:   var1-1:     var1-1-1:     ...   var1-2:     var1-2-1:     ... var2: ...

and task:

- copy:     src: "{{ var1.var1-1.var1-1-1 }}"     dest: /root/

but operator don't specify var1 @ task failed. can workaround problem with

  when: var1 defined , var1.var1-1 defined , var1.var1-1.var1-1-1 defined

but looks awful. unfortunately, var1.var1-1.var1-1-1|default({}) not working case , can't use simple variables without encapsulation.

is there better way check if parent object defined?
