Generate temaplate file when having with_items and array

[dudu.c...@gmail.com]

I need to generate few files based on jinja template ,

In the first run it is easy when I need to generate single file per user

  

Basic input:

user:
    - { username: user1, action: get , file: 1.txt }
    - { username: user2, action: get , file: 2.txt }

 

Jinja template:

User: {{ item.users }}
Permission: {{ item.action}}
File-access: {{ite.file}}

 Playbook:

- name: generate files
  template:
    src: template.j2
    dest: "{{ folder }}/{{ item.username }}"
  with_items: "{{ user }}"

 

 

But now comes the twist, Single user can have multi files  (see user1) and , I need to create for this user 2 files

File 1 – filename user1-1 , where file = to 1.txt

File 2 – filename user1-2 , where file = to new.file

 

Advance input:

user:
    - { username: user1, action: get , file: [1.txt ,new.file] }
    - { username: user2, action: get , file: 2.txt }

 

Any ideas ?

A loop with subelements should give you the control you need to template out what you need based on the number of files in the data structure:

- name: test jinja rendering
  hosts: localhost
  gather_facts: no

  vars:
    users:
      - username: user1
        action: GET
        files:
          - file1
      - username: user2
        action: GET
        files:
          - file1
          - file2

  tasks:
    - name: debug the data structure
      ansible.builtin.debug:
        msg:
          - Item 0 is '{{ item.0 }}'
          - Item 1 is '{{ item.1 }}'
      loop: '{{ users | subelements("files") }}'

Sample debug output:

TASK [debug the data structure] ************************************************
ok: [localhost] => (item=[{'username': 'user1', 'action': 'GET', 'files': ['file1']}, 'file1']) => {
    "msg": [
        "Item 0 is '{'username': 'user1', 'action': 'GET', 'files': ['file1']}'",
        "Item 1 is 'file1'"
    ]
}
ok: [localhost] => (item=[{'username': 'user2', 'action': 'GET', 'files': ['file1', 'file2']}, 'file1']) => {
    "msg": [
        "Item 0 is '{'username': 'user2', 'action': 'GET', 'files': ['file1', 'file2']}'",
        "Item 1 is 'file1'"
    ]
}
ok: [localhost] => (item=[{'username': 'user2', 'action': 'GET', 'files': ['file1', 'file2']}, 'file2']) => {
    "msg": [
        "Item 0 is '{'username': 'user2', 'action': 'GET', 'files': ['file1', 'file2']}'",
        "Item 1 is 'file2'"
    ]
}
