Additionally I've updated the underlying django like described here <https://groups.google.com/forum/#!searchin/mezzanine-users/django$202$20mezzanine%7Csort:date/mezzanine-users/sI2dgMP2r_Y/KCxZinF9AQAJ> . So I ended up with the following *environment* in short: - Python 3.5 - Django 2.0.13 - Mezzanine 4.3.1
After some tests and some adaptions due to incompatibility between django and mezzanine, everything works fine, now, except one issue with comment: *Test steps:* After allowing a comment in blog post (admin), I write a comment, and after sending the comment I get: ValueError at /blog/set-up-codesample-plugin-of-tinymce-for-mezzanine/ dictionary update sequence element #0 has length 3; 2 is required Request Method: GET Request URL: http://localhost:8000/blog/set-up-codesample-plugin-of-tinymce-for-mezzanine/ Django Version: 2.0.13 Exception Type: ValueError Exception Value: dictionary update sequence element #0 has length 3; 2 is required Exception Location: /Users/saeed/Development/django/venv_unitecinfo/lib/python3.5/site-packages/django/template/context.py in flatten, line 123 Python Executable: /Users/saeed/Development/django/venv_unitecinfo/bin/python Python Version: 3.5.2 Python Path: ['/Users/saeed/Development/django/unitecinfo', '/usr/local/Cellar/python3/3.5.2_3/Frameworks/Python.framework/Versions/3.5/lib/python35.zip', '/usr/local/Cellar/python3/3.5.2_3/Frameworks/Python.framework/Versions/3.5/lib/python3.5', '/usr/local/Cellar/python3/3.5.2_3/Frameworks/Python.framework/Versions/3.5/lib/python3.5/plat-darwin', '/usr/local/Cellar/python3/3.5.2_3/Frameworks/Python.framework/Versions/3.5/lib/python3.5/lib-dynload', '/Users/saeed/Development/django/venv_unitecinfo/lib/python3.5/site-packages'] Server time: Sun, 30 Jun 2019 17:36:42 +0200 Error during template rendering In template /Users/saeed/Development/django/unitecinfo/theme/templates/generic/includes/comment.html, error at line *73* dictionary update sequence element #0 has length 3; 2 is required 63 {# Uncomment for debugging only. #} 64 <p> My id: {{ comment.id }}, I replied to: {{comment.replied_to_id}}</p> 65 <p> Do I have children? {% if comment.id in all_comments|defaultdict_keys %} yes {% else %} no {% endif %} </p> 66 <p> What is my level in the tree?: {{ comment|comment_level }}</p> 67 {% endcomment %} 68 69 <div class="comment-border clearfix"> 70 71 {% if settings.COMMENTS_USE_RATINGS %} 72 <div class="rating"> 73 {% rating_for comment %} 74 </div> 75 {% endif %} The problem occurs when mezzanine uses flatten function of django context.py - /Users/saeed/Development/django/venv_unitecinfo/lib/python3.5/site-packages/mezzanine/generic/templatetags/rating_tags.py in rating_for 1. ... ▼ Local vars <http://localhost:8000/blog/set-up-codesample-plugin-of-tinymce-for-mezzanine/#> VariableValue context [{'True': True, 'None': None, 'False': False}, [{'True': True, 'None': None, 'False': False}, {'has_home': True, 'menu_pages': defaultdict(<class 'list'>, {8: [<Page: Portfolios / Software Development>, <Page: Portfolios / Test Automation>, <Page: Portfolios / IT Consulting>], 9: [<Page: Portfolios / Software Development / Microservices>, <Page: Portfolios / Software Development / Web Crawler>, <Page: Portfolios / Software Development / Web Apps>, <Page: Portfolios / Software Development / PDF parser>, <Page: Portfolios / Software Development / Big Data + ETL>], None: [<Page: Home>, <Page: Blog>, <Page: Features>, <Page: Portfolios>, <Page: Testimonials>, <Page: Contact us>, <Page: Pages>], 11: [<Page: Portfolios / IT Consulting / Test Management>, <Page: Portfolios / IT Consulting / Test Process Improvement>], 10: [<Page: Portfolios / Test Automation / Qt C++ GUI>, <Page: Portfolios / Test Automation / Java Client Server GUI>, <Page: Portfolios / Test Automation / Web Apps>], 14: [<Page: Example pages / About us>, <Page: Pages / Resume>]}), 'False': False, 'STATIC_URL': '/static/', 'settings': {'COMMENTS_DISQUS_SHORTNAME': '', 'PERSONAL_PHONE': '+49 69-967-516-00', 'SOCIAL_LINK_TUMBLR': 'https://tumblr.com/test', 'DEV_SERVER': True, 'COMMENTS_DISQUS_API_PUBLIC_KEY': '', 'SITE_TITLE': 'unitec informatics', 'JQUERY_UI_FILENAME': 'jquery-ui-1.8.24.min.js', 'PERSONAL_EMAIL': 'You want to write us?', 'SITE_TAGLINE': 'You are a serious company.
