Mezzanine | game engine that supports high performance 3d graphics | Game Engine library

This is related to this issue in Django: https://code.djangoproject.com/ticket/29182. It is caused by a new behavior introduced in sqlite 3.26. Django has patched it in latest 2.0 and 2.1, but mezzanine does not support Django 2 yet.

The easiest fix is to not use sqlite - switch to postgres, mysql, etc. Alternatively, downgrade sqlite to < 3.26

I figured this issue out. It has something to do with the EXTRA_MODEL_FIELDS option in the settings.py file. I'm still not sure why that causes an issue, but here is my EXTRA_MODEL_FIELDS code:

1. case_when is type-strict meaning you need to return values of same type. For first few cases you are returning values like "ground-floor", "mezzanine" etc whereas later you are returning 1, 2 which are numeric hence you get that error. If you change all your return values to character values like "1", "2" etc then it will work.

2. Since, you are just returning the floor values you can reduce the code by:

I don't think it is possible to overlay different table rows over each other (someone correct me if i'm wrong) so I instead moved your top header containing the logo into a seperate div outside of the table and applied a negative margin to the table itself:

The docs say:

Deprecated since version 3.3, will be removed in version 3.5: This exception has been deprecated because it’s never raised by the parser (when the default non-strict mode is used).

It was removed because nothing raised it unless the (presumably) little used strict mode is used, so a question must be asked: "are you using the strict mode?"

If you are not, you can safely remove the import and the code that catches it.

If you are, check what exception is raised instead (if at all), and import it instead.

If you use strict mode and have to support both versions of Python, you can do something along the lines of

As noted in the comments, your current code is missing a couple of single quotes to terminate the strings that you are testing, and would be better written using a single switch statement rather than multiple nested iif statements, e.g.:

This is just an indention issue. Outdent your items = items - 1 because it is inside your last elif statement.

Deployment tips

1. Install apache2 mod_wsgi
2. set hostname and add it into /etc/hosts with hostname and your public ip
3. Install virtualenv and remove python libraries conflict.sudo apt install virtualenv
4. Remove default page in /etc/apache2/site-available
5. Disable default site sudo a2dissite default-000.conf
6. Create new site settings in /etc/apache2/site-available
7. Enable site by sudo a2ensite my site.conf
8. Install,edit and enable firewall, for example
9. sudo ufw allow 8000
10. sudo ufw allow http
11. sudo ufw allow outgoing and deny incoming except ssh
12. sudo ufw enable(for first time)
13. Chown static media forlder and edit it's permission
14. Add allowed host in settings.py
15. Checkout deployment checklist in django official website and do it.

For apache configuration please visit https://pythonprogramming.net/deploying-to-server-django-tutorial/

1. Edit the path given in your apache configuration (path in WSGI Script path for python-path, python-home ) if any errors found like Internal server error, miss configuration etc
2. For python-home path please refer Get virtualenv's bin folder path from script
3. You can also add python-path to WSGIDaemonProcess
4. Additional tip, you can visit puttygen

Use .stripped_strings property to get clean, stripped texts out of HTML.
