How to access status in ansible_facts.services?

I am trying to Stop and/or Disable a systemd service if it is running and/or enabled on the remote host.

Contents of tasks/main.yml:

---
- name: Populate service facts
  service_facts:

- name: Display selected service
  debug:
    var: ansible_facts.services[serviceToDisplay]
  loop: "{{ disable_services }}"
  loop_control:
    loop_var: serviceToDisplay
  vars:
    disable_services:
      - cups.service
      - cups

- name: Stop and Disable service if it is running or enabled
  systemd:
    name: cups.service
    enabled: false
    state: stopped
  when:
    - "serviceToDisable is defined"
    - "serviceToDisable.status == 'enabled'"
  loop: "{{ disable_services }}"
  loop_control:
    loop_var: serviceToDisable
  vars:
    disable_services:
      - cups.service
      - cups
  become: true
...

Results:

Ansible version: 2.9.14-1.fc32 on Fedora

How should I go about checking if the status == enabled or the state == running?

Note: The service may optionally not be present in ansible_facts.service. It may also optionally not be running and/or not enabled. I am attempting to make the tasks idempotent.

Thanks

Your second task should be as below, please notice the name clause and the when section:

  - name: Stop and Disable service if it is running or enabled
    systemd:
      name: "{{ ansible_facts.services[serviceToDisable]['name'] }}"
      enabled: false
      state: stopped
    when:
      - serviceToDisable is defined
      - ansible_facts.services[serviceToDisable]['status'] == 'enabled'
    loop: "{{ disable_services }}"
    loop_control:
      loop_var: serviceToDisable
    vars:
      disable_services:
        - cups.service
        - cups
    become: true

Not sure why you have defined two times the same service (cups.service and cups), but I guess you have your good reasons.
