Can't use tpldir or slspath in template file

Can't use tpldir or slspath in template file

I want to load defaults with construction like this

{%- import_yaml slspath ~ "/defaults.yaml" as defaults %}

Which work flawless in sls state file. But fails in template file. On #salt IRC channel I received a recommendation to use 'tpldir' variable instead, but it doesn't work as well.

Setup

init.sls

{%- import_yaml slspath ~ "/defaults.yaml" as defaults %}
config:
  file.managed:
    - name: "/tmp/test.cfg"
    - source: salt://{{ slspath }}/test.cfg.jinja
    - template: jinja

test.cfg.jinja

{%- import_yaml tpldir ~ "/defaults.yaml" as defaults %}
opt1 = var1
opt2 = var2

With setup like this I receive error:

          ID: config
    Function: file.managed
        Name: /tmp/test.cfg
      Result: False

When they said to use tpldir, did they mention where in salt that was documented? because i cannot find it in the documents at all :/ It might be just a jinja thing.

Can you try using

{%- import_yaml "defaults.yaml" as defaults %} ? i wonder if it will allow relative paths.

I am looking into this further.

Thanks,
Daniel

ahh, i see it referenced in salt.utils.jinja

I have tried {%- import_yaml "defaults.yaml" as defaults %} my bad I doesn't mentioned it straight away, but it doesn't work too.

And about documentation, it isn't documented anywhere, only in code and in other issues. Mostly discussed here #4348.

[gtmanfred]

ok, let me take a look closer, because I see where it should be injecting it into the template environment in salt.utils.jinja.
