Is there anything like the "default(omit)" filter available for ordinary
variable declarations?
I am building a list of volume details, which will be passed too the ec2
module. With module parameters, one can comvert an undefined parameter inot
no parameter at all with the "default(omit)" filter, but I cn't find a way
to simply leave out an undefined item from the list I m building.
Say my input is a list of tables like this:
alist:
- { 'fred': value1, 'mary': value2 }
- { 'fred: value3 }
I want to process that list into another list using set_fact, so:
- set_fact:
mylist: "{{ mylist + [ {'this': item.fred, 'that': item.mary } ] }}"
with_items: "{{ alist }}"
... and end up with
{ 'this': value1, 'that': value2}
{ 'this': value3 }
But I can't figure out how to omit item.mary if it is undefined.
Any clues?
Regards, K.
