(Migrate may not be the correct term I'm unsure) I'm trying to figure out how to change my Django site to register SQLite. Originally SQLite is the default for Django however I changed to MySQL because the original site I was going to host on (GoDaddy) was compatible with it. The only solution I thought of so far is changing the DATABASES info in my Settings.py. After changing my Settings to the defaults of
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': BASE_DIR / 'db.sqlite3',
I ran into this error,

I'm tryin to deploy to Heroku and before this error I was getting:
ModuleNotFoundError: No module named 'django-tables2'
Then I installed django-heroku via pip install django-heroku, followed the instructions on how to set it up.
I disabled the collect static for heroku pushed my master branch and everything is fine, but once I do:
heroku run python manage.py migrate
I get the:
ModuleNotFoundError: No module named 'django_heroku'
the complete traceback is this:

ModuleNotFoundError: No module named 'django_heroku'
I have in my settings at the top:
import os
import django_heroku
and in the very bottom:
django_heroku.settings(locals())
in my requirements.txt I have django-heroku
The master branch is updated and I just can find how to fix this.
The problem was that it was not added to the module, it was needed to be added to the virtual env and then do the pip freeze, with that it was solved.
My problem is this: When I try to do the migrations, it gives me the following error:
python3 manage.py makemigrations

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
Thing is, I've never told django to use MySQL, in fact, the settings.py states that it has to use SQLite:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'gestlote.db'),
}
}
I've alreay tried to reinstall django, upgrade it, pip3 install pysqlite, but nothing seems to work.
So please, help me
I have an issue with migration in Django using python3 manage.py migrate it shows me about memoize
I have installed django-memoize and included it on my settings.py but it still shows the error.

It should have migrated after installation of memoize.
Thank you for all the support I need to install some dependencies and re-install my python then after that I created a virtual environment and install dependencies.
Prepare the database for SALEOR:
$ python manage.py migrate
This command will need to be able to create database extensions. If you get an error related to the CREATE EXTENSION command please review the notes from the user creation step.
# python3 manage.py migrate
