State exists for group of items

[Patrick Heeney]

I keep running into this a lot but I am not sure how to handle it. Lets assume I have the following yaml:

project_paths:

  - path: /srv/www/web/app1

    name: app1

  - path: /srv/www/web/app2

    name: app2

Then I want to check if a file exists before running the following action:

- name: application | check for installer

  stat: path={{ item.path }}/install.php

  register: check_install

  with_items: project_paths

- name: application | run install

  command: php install.php chdir={{ item.path }}

  with_items: project_paths

  when: check_install.stat.exists == false

The issue is registering check_install since we are doing it in a loop. It looks to be resetting the variable for every item. I tried something like this and I get 'check_install' is undefined.

- name: application | check for installer

  stat: path={{ item.path }}/install.php

  register: check_install[item.name]

  with_items: project_paths

- name: application | run install

  command: php install.php chdir={{ item.path }}

  with_items: project_paths

  when: check_install[item.name].stat.exists == false

- name: done

  fail: msg="{{ item.name } installer does not exist"

  with_items: project_paths

  when: check_install[item.name].stat.exists == false

Basically I am wondering the best way to run stat or other register commands with_items so that I can later check that on other with_item tasks for the same variables.

Verify the results of a registered variable like so:

- debug: var=register

Thank you! This is the code I ended up with for anyone that stumbles upon this:

- debug: >

    msg="{{ item.0.path }} - {{ item.1.stat.exists }}"

  with_together: 

    - project_paths

    - check_install.results

- name: application | run install

  command: php install.php chdir={{ item.0.path }}

  with_together: 

    - project_paths

    - check_install.results

  when: item.1.stat.exists
