ISSUE TYPE
COMPONENT NAME
ansible core
ANSIBLE VERSION
ansible 2.2.0.0
config file =
configured module search path = Default w/o overrides
CONFIGURATION
Defaults.
OS / ENVIRONMENT
N/A (tested on CentOS 7, Ubuntu 16.04, Fedora 25)
SUMMARY
Ansible 2.2.0.0 with jinja2 < 2.9 will handle a variable with curly braces properly in self_eval(). However, jinja >= 2.9 fails with an exception.
STEPS TO REPRODUCE
Here's an example playbook:
---
- hosts: all
vars:
fruits:
- name: apple
enjoy: yes
- name: orange
enjoy: no
- name: strawberry
enjoy: yes
tasks:
- name: Loop through my fruits
debug:
msg: |
{% set fruit_list = [] %}
{% for fruit_dict in item[1] %}
{{ fruit_dict.name }}
{% endfor %}
with_items:
- "{{ fruits | groupby('enjoy') }}"Start with jinja2 2.8.1. The playbook should execute successfully. Upgrade to jinja2 2.9 (or higher). The playbook will have an error (see below).
EXPECTED RESULTS
The playbook should run without errors.
ACTUAL RESULTS
TASK [Loop through my fruits] **************************************************
[WARNING]: Exception in safe_eval() on expr: [_GroupTuple(grouper=False, list=[{u'enjoy': False, u'name': u'orange'}]), _GroupTuple(grouper=True,

False, u'name': u'orange'}]), _GroupTuple(grouper=True, list=[{u'enjoy': True, u'name': u'apple'}, {u'enjoy': True, u'name': u'strawberry'}])]))
fatal: [localhost]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'unicode object' has no attribute 'name'\n\nThe error appears to have been in '/tmp/ansible/playbook.yml': line 14, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Loop through my fruits\n ^ here\n"}
I still get the same problem if I install ansible from the latest commit in git.
