Issue with jinja2 template

[lift...@gmail.com]

I'm trying to create a report when we do our updates via yum (rhel 7) and dnf (rhel 8).  I register the output in variables called yum_rhel7 and yum _rhel8.  Here's my j2 file:

Yum/DNF Update Report

{{ now(false, '%m/%d/%Y %I:%M:%S') }}

---

{% for i in play_hosts | sort %}

{% if {{ hostvars[i]['ansible_distribution_major_version'] == '7' }} %}

{% if {{ hostvars[i]['yum_rhel7']['skipped'] is not defined }} %}

  Host: {{ i }}

  Yum Result: {{ hostvars[i]['yum_rhel7']['results'] }}

{% endif %}

{% endif %}

---

{% endfor %}

I'm getting the following error when I run the playbook:

fatal: [localhost]: FAILED! => {"changed": false, "msg": "AnsibleError: template error while templating string: expected token ':', got '}'. String: Yum/DNF Update Report\n\n{{ now(false, '%m/%d/%Y %I:%M:%S') }}\n\n---\n{% for i in play_hosts | sort %}\n{% if {{ hostvars[i]['ansible_distribution_major_version'] == '7' }} %}\n{% if {{ hostvars[i]['yum_rhel7']['skipped'] is not defined }} %}\n  Host: {{ i }}\n  Yum Result: {{ hostvars[i]['yum_rhel7']['results'] }}\n{% endif %}\n{% endif %}\n---\n{% endfor %}\n\n"}

Any ideas on what I'm doing wrong?

Thanks,

Harry

No curly braces in conditions, e.g. use

{% if hostvars[i]['ansible_distribution_major_version'] == '7' %}

Also

{% if 'skipped' not in hostvars[i]['yum_rhel7'] %}

is probably more correct.
