implementing hashes

[Brandon Metcalf]

It seems this should work according to the docs.  It does work if I use

with_items: app1

$ cat jj.yml

---

- hosts: all

  vars:

    app1:

      - base: "{{ file | basename }}"

    app2:

      - base: "{{ file }}"

  tasks:

      - name: debug

        debug: msg="{{ item.base }}"

        with_items:

          - app1

          - app2

$ ansible-playbook ./jj.yml -i hosts --extra-vars 'file=/tmp/jj'

...

TASK: [debug] *****************************************************************

fatal: [myhost] => One or more undefined variables: 'str' object has no attribute 'base'

What am I doing wrong?  Thanks.

In the above, app1 and app2 are not hashes, but lists of strings.

I think you would want to define them like:

app2: { base: "foo" }

etc

But really probably

apps:

   - { name: app1, base: foo }

   - { name: app2, base: bar }

tasks:

   - blarg: ...

     with_items: apps

Etc.

Let me know if you'd like more detail on some of the above, but that should get you started.

Thanks, Michael.   I was able to get something like that working.  However, what I ultimately need is the ability to control the order in which app1 and app2 are operated on within certain tasks.  For some tasks, I need to operate on app1 first and for others app2 first.

You could still keep the data in the hash and then traverse an array.

thing_details[item]['hash_key']

where thing_details is a hash

and you're traversing across a with_items: thing_names
