Re: [ansible-project] Stuck: One or more undefined variables: 'str object' has no attribute 'base'

Hi Michael,

Thank you for your feedback.

Yes, where you are defining "test" some of the items in that list are
hash tables that don't have a value for "base", which is why you are
getting that error.

Clearly I need to read more about lists, hashes and dicts. Not being a 
developer, please stand by while I try to wrap my head around them :)

Easiest would be to set it to empty string when it does not apply.

I couldn't figure that out but in the docs I found 'Nested Loops' that 
seemed promising. For the archives, here's how I got it working:

------
# file: roles/common/tasks/main.yml

- name: dirs | Include vars
  include_vars: main.yml

- name: dirs | Create some directories
  file:
    dest: "{{ item.0.base }}{{ item.0.usr }}/{{ item.1 }}"
    mode: 0750
    state: directory
  with_nested:
    - users
    - dirs

---
# file: roles/common/vars/main.yml

users:
  - usr: patrick
    base: /home/
  - usr: root
    base: /

dirs:
  - test1
  - test2


However, it's a little weird that it says "str object", which seems to
imply you have, probably in that "dirs" variable file, refined the
variable "test" to a list of strings, as opposed to a list of hash elements.

FWIW it's Ansible 1.7.1 on Fedora 20 x86_64. If weird means bug, please 
let me know if you'd like me to file a ticket on github.

Thanks,
Patrick

    Hi all,

    New to the list. Been playing with Ansible for a few hours and I
    could use a hand in getting a task going. I've not figured out any
    of the YAML magic so please excuse the undoubtedly spectacular errors :)

    Goal: create a task that installs a couple of directories in
    /home/patrick and /root.

    ---
    # file: roles/common/tasks/main.yml

    - name: dirs | Include vars
       include_vars: main.yml

    - name: dirs | Create some directories
       file:
         dest: "{{ item.base }}/{{ item.usr }}/{{ item.dirs }}"
         mode: 0750
         owner: "{{ item.usr }}"
         group: "{{ item.usr }}"
         state: directory
       with_items: test

    ---
    # file: roles/common/vars/main.yml

    test:
       - usr: patrick
         base: /home
       - usr: root
         base: /
       - dirs: test1
       - dirs: test2


    When I run this with:
    $ ansible-playbook -v -i stage site.yml

    I get:
    TASK: [common | dirs | Create some directories]
    ******************************__*
    fatal: [test.local] => One or more undefined variables: 'str object'
    has no attribute 'base'

    I'm guessing that the issue is in vars/main.yml file but lots of
    Googling and staring at Github/Galaxy examples did not reveal a
    solution. Can anyone please enlighten me a bit?

    Thanks,
    Patrick
