So, to address the problem with saving boolean parameters as true/false instead of string values 'true'/'false' we need to cherry pick this https://github.com/theforeman/foreman_ansible/pull/293/files into Satellite.

The YAML render should be also fixed by implementing the proposed change. I'll create a PR for that.

Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/29138 has been resolved.

VERIFIED.

tfm-rubygem-foreman_ansible-5.1.3-1.el7sat.noarch

by the reproducer described in comment#0 and comment#4:

1) Import the role "linux-system-roles.timesync" and its variables (works for any role with boolean variables)

# ansible-galaxy install -p /etc/ansible/roles linux-system-roles.timesync
# hammer ansible roles import --proxy-id 1
# hammer ansible variables import --proxy-id 1

2) Associate this role to an host

# hammer host ansible-roles assign --name $(hostname) --ansible-roles linux-system-roles.timesync

3) Override variable "timesync_dhcp_ntp_servers" and leave the default value to 'false'

4) Access the YAML page of your host and check for the variable "timesync_dhcp_ntp_servers"

---
parameters:
  timesync_dhcp_ntp_servers: false

>>> boolean parameter set to false is still visible


5) Change the overridden value to 'true' and check its representation in foreman database

# PGPASSWORD=$(awk '/password:/{gsub(/"/,"",$2);print$2}' /etc/foreman/database.yml) psql -U foreman -d foreman -h 127.0.0.1
psql (12.1)
Type "help" for help.

foreman=> select default_value from lookup_keys where key like 'timesync_dhcp_ntp_servers';
 default_value 
---------------
 --- true     +
 ...          +
 
(1 row)

>>> boolean variable is stored as a boolean and not as a string
