complex dictionary reference including "item" question

[je...@soundhound.com]

Hi,

I am wondering if it possible to do this kind of form in a playbook. I know how to do it in a template:

If I have some  data of the form:

mydict:

  - entry1:

      data: xyzzy

      filename: scroll.txt

  - entry2:

       data: boom

       filename: sound.txt

things:

  - entry1

  - entry2

In a template, I can to do this:

{% for item in things %}

data = {{ mydict[item]['data'] }}

filename = {{ mydict[item]['filename'] }}

{% endfor %}

What I want to do is in a role task is

- name test copy from variable

  copy:

    content: "{{ mydict[item]['data'] }}

    dest: "{{ target_dir }}/{{ mydict[item]['filename'] }}'

  with_items: things

I can't seem to find the right way to get this to work in a playbook. All my attempts with dots and brackets have failed.

Can someone explain how to represent this in a playbook?

thanks in advance,

jerry

Are you sure this work?
This will fail in the same way as your task below.

mydict is not a dict but a list.
So correct syntax is
{{ mydict[item][0]['data'] }} for the first and {{
mydict[item][1]['data'] }} for the second.

If you remove the dashes in front of entry1 and 2 you'll get a dict and
both of your examples will work.

You may be able to make this work with a simple:

- name test copy from variable
copy:

content: "{{ item.data }}
dest: "{{ target_dir }}/{{ item.filename }}'
with_items: "{{ mydict }}"

Why do You need an extra list?
