I have previously restored the database for the system, and while i tried to migrate through the django applicaion, the following error is thrown. What is the possible cause and how can we mitigate such cases. I guess the problem is with the existing table conflict, will it solve the issue by delete/dropping the conflicting tables.

I had the same problem and solved it by deleting the database a running the inital migrations again
I'm setting up a database in django, while trying to flush the database i get the following error:
You have requested a flush of the database.
This will IRREVERSIBLY DESTROY all data currently in the "/home/luc/projects/PySorge/API/db.sqlite3" database,
and return each table to an empty state.
Are you sure you want to do this?

django.db.utils.OperationalError: duplicate column name: ID
I'm using django version 3.1.6. I'm not really sure how to fix this as I'm not very familiar with databases. Seems like the error is caused by a duplicate field id - my current database setup does have a field named ID.
My recommendation, although certainly not the best way forward, would be to delete the database (delete the actual sqlite3 file in your project) then delete all of your previous migrations, and then try making migrations again.
I had a very old Django site (still had South migrations in tree!) that had been ticking along on a SQLite database forever. At some point Django removed the name column from the django_content_types table. The model uses a property now based on the reflected model class. I've no idea why this hadn't be caught by a Django migration, but I've been known to fake migrations in the blood mist of getting something to run, no-matter-what.
I just dropped the column in ./manage.py dbshell:
ALTER TABLE django_content_type DROP COLUMN name;
And migrations worked again. No ill effects felt. All my old contenttypes are in there, everything still works.
python manage.py reset_db
This will delete all tables. It also helps to delete all migration files in the project if you want a complete wipeout
I tried to install Saleor but during
./manage.py migrate
i get

I want my project to serve all world cities by using Django-cities.
First and after facing many problems, I made my SQLite accept spacial queries by using advice in this tutorial and this question.
So far I can run "makemigrations" but when I run "migrate" I receive: unexpected metadata layout.
I think the answer to my problem is included in this question but I'm not sure how to apply it in a Django project.
This is full text of the error when I run "migrate":

django.db.utils.OperationalError: table cities_city__new has no column named location
I'm trying to set up django-notifications in my app. I'm following the instructions to install it, which are pretty straight-forward: https://github.com/brantyoung/django-notifications#installation
When I run manage.py migrate notifications I get:
django.db.utils.ProgrammingError: (1146, "Table '{{database}}.notifications_notification' doesn't exist")
I'm at a loss.

You forget to run syncdb before migrating data. The table doesn't exists because it's syncdb that created it, not the migration.
Reference: http://south.readthedocs.org/en/latest/tutorial/part1.html
(If this fails complaining that south_migrationhistory does not exist, you forgot to run syncdb after you installed South.)
