Could a value refer another key’s value as variable

[David Wong]

Hi,

I would like to do something in playbook like

myapp:

  version: 1.2

  path: xxxx_{{version}

I want to refer another key’s value to devise new value. It does not work. 

Is it possible at all?

Regards,

David

I do this all the time, but I always quote the RHS of each assignment.  NOTE also that you are missing a closing brace in your example code.

Hi John

Thank for your reply, do you mean quoting like this:

---

- hosts: localhost

  vars:

    record:

      field1: 1

      field2: "{{field1}}"

  tasks:

   - name: This one does not work

     debug: msg="{{record.field2}}"

...

I still get error:

fatal: [localhost]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: {u'field2': u'{{field1}}', u'field1': 1}: 'field1' is undefined\n\nThe error appears to have been in 'xxxxx.yml': line 8, column 6, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n  tasks:\n   - name: This one does not work\n     ^ here\n"}

Does field2's value display correctly if you use the full path to the other variable?

Hi Joanna,

I tried that as well, it still did not work, it will fail with:

.....recursive loop detected in template string: {{record.field1}}"}
