OperationalError, no such column. Django

Question

I am very new to django and was able to finish the tutorial on djangoproject.com without any errors. I am now going through the Django REST framework tutorial found at http:

Answer 1

just remember there is a pycache folder hidden inside the migrations folder so if you change your models and delete all your migration files you MUST delete the pycache folder also.

The only one you should not delete is your init file.

Hope this helps

Answer 2

This error can happen if you instantiate a class that relies on that table, for example in views.py.

Answer 3

Step 1: Delete the db.sqlite3 file.

Step 2 : $ python manage.py migrate

Step 3 : $ python manage.py makemigrations

Step 4: Create the super user using $ python manage.py createsuperuser

new db.sqlite3 will generates automatically

Answer 4

Taken from Burhan Khalid's answer and his comment about migrations: what worked for me was removing the content of the "migrations" folder along with the database, and then running manage.py migrate. Removing the database is not enough because of the saved information about table structure in the migrations folder.

Answer 5

I see we have the same problem here, I have the same error. I want to write this for the future user who will experience the same error. After making changes to your class Snippet model like @Burhan Khalid said, you must migrate tables:

python manage.py makemigrations snippets
python manage.py migrate

And that should resolve the error. Enjoy.

Answer 6

The most direct way of solving this type of problem is just the following 3 steps process:

1. Delete all the migration related files from app's migrations folder/directory (these basically starts with 0001, 0002, 0003 etc).

2. Delete/Rename the existing database file named db.sqlite3 from App directory.

3. Now run the following command:

   python manage.py migrate

   Finally execute

   python manage.py createsuperuser

   to perform the administrative tasks (If you want).
