Ansible - install oh my fish for each fish user - ansible

Question

I'm writing a playbook to install 'oh my fish' for all local fish user.
I want trigger the install for local fish user (default shell set to /usr/bin/fish)
And ONLY if 'omf' is not installed in their home (check the presence ~/.local/share/omf directory)
Here what I produced
- name: Read local user database
getent:
database: passwd
- name: List local user of fish
set_fact:
fish_users: "{{ getent_passwd | dict2items | json_query('[? contains(value, `/usr/bin/fish`)].key') }}"
- name: Check if omf install for fish users
stat:
path: "/home/{{ item }}/.local/share/omf"
loop: "{{ fish_users }}"
register: omf_user_status
- name: Install omf when absent of fish user home
block:
- name: Get last omf repos
git:
repo: 'https://github.com/oh-my-fish/oh-my-fish'
dest: '/tmp/omf'
clone: yes
- name: Installing omf for fish user
become: yes
become_user: "{{ item }}"
command: /tmp/omf/bin/install -y --offline --noninteractive
loop: "{{ fish_users }}"
when: omf_user_status.item.stat.exists == 'False'
So maybe my approach is not good...
Currently I can get 'omf', installed for all fish users.
But I really struggle to generate a usable list , to only install omf for user who haven't it
Obviously the condition doesn't work.
omf_user_status variable is a dict, here an example of the content.
"omf_user_status": {
"changed": false,

"results": [

I finally make it works with this code.
- name: Register users who need omf
set_fact:
list_of_user: "{{ omf_user_status.results | rejectattr('stat.exists') | map(attribute='item') | list }}"
Here the full plabook
# OMF install
- name: Read local user database
getent:
database: passwd
- name: List local user of fish
set_fact:
fish_users: "{{ getent_passwd | dict2items | json_query('[? contains(value, `/usr/bin/fish`)].key') }}"
- name: Check if omf is installed for fish users
stat:
path: "/home/{{ item }}/.local/share/omf"
loop: "{{ fish_users }}"
register: omf_user_status
- name: Register users who need omf
set_fact:
user_need_omf: "{{ omf_user_status.results | rejectattr('stat.exists') | map(attribute='item') | list }}"
- name: Install omf when absent of fish user's home
block:
- name: Get lastest omf from git
git:
repo: 'https://github.com/oh-my-fish/oh-my-fish'
dest: '/tmp/omf'
clone: yes
- name: Installing omf for fish user
become: yes
become_user: "{{ item }}"
command: /tmp/omf/bin/install -y --offline --noninteractive
loop: "{{ user_need_omf }}"
- name: Cleanup omf install files
file:
path: '/tmp/omf'
state: absent
# only run this block if the user_need_omf list is not empty
when: user_need_omf | length > 0
