[ansible-project] strange jinja logic

[Barry Kaplan]

I have:

- debug: var=_consul_install_agent
- debug: var=consul_use_dnsmasq
- debug: msg="{{_consul_install_agent and consul_use_dnsmasq}}"


The two variables are true and false respectively, but the expression
evaluates to true?


TASK: [consul | debug var=_consul_install_agent]
******************************
ok: [10.0.196.112] => {
"var": {
"_consul_install_agent": "False"
}
}


TASK: [consul | debug var=consul_use_dnsmasq]
*********************************
ok: [10.0.196.112] => {
"var": {
"consul_use_dnsmasq": "True"
}
}


TASK: [consul | debug msg="{{_consul_install_agent and consul_use_dnsmasq}}"
] ***
ok: [10.0.196.112] => {
"msg": "True"
}


But if the expression is

- debug: msg="{{_consul_install_agent == true and consul_use_dnsmasq ==
true}}"

Then it evals to false.

Is this expected with jinja? Without the 'and' the '== true' seems not
necessary.

There's a high likelihood that their type is actually 'string' instead of
boolean, try

- debug: msg="{{ (_consul_install_agent | bool) and (consult_use_dnsmasq |
bool) }}"

Indeed. The values were "== *'*True*'*" not "== True". Thanks!
