complex dictionary reference including "item" question

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

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 %}

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

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

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?
