How to access status in ansible_facts.services? - ansible

Question

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
...

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.
