I have such a variable:

apps: - {name: kapitalism, extension: .war} - {name: socialism, extension: .war} - {name: somethingelse, extension: .ear}

And I need to make another one based on it, which will not include some of the list. I'm trying this:

- name: Reject this please set_fact: apps: "{{ apps | map(attribute='name') | reject('search',item.name) | list }}" when: "item.name.find('socialism') != -1" with_items: "{{ apps }}"

But here I get such a problem that the extension parameter is lost and I get the variable:

apps: [u'kapitalism', u'somethingelse']

How to make a variable like this:

apps: - {name: kapitalism, extension: .war} - {name: somethingelse, extension: .ear}

?

The play below

- hosts: localhost vars: apps2: [] apps: - {name: A, extension: .ab} - {name: B, extension: .ab} - {name: C, extension: .c} tasks: - set_fact: apps2: "{{ apps2 + [item] }}" loop: "{{ apps }}" when: item.name != 'C' - debug: var: apps2

gives (abridged):

 apps2: - extension: .ab name: A - extension: .ab name: B

The same result can be achieved by rejectattr

 - set_fact: apps2: "{{ apps|rejectattr('name', 'match', '^C$') }}"
