Fix Python – How to reset db in Django? I get a command ‘reset’ not found error

Following this Django by Example tutotrial here: http://lightbird.net/dbe/todo_list.html

The tutorial says:

“This changes our table layout and we’ll have to ask Django to reset
and recreate tables:

manage.py reset todo; manage.py syncdb“

though, when I run manage.py reset todo, I get the error:

$ python manage.py reset todo                                       
- Unknown command: 'reset'

Is this because I am using sqlite3 and not postgresql?

Can somebody tell me what the command is to reset the database?

The command: python manage.py sqlclear todo returns the error:

$ python manage.py sqlclear todo    
CommandError: App with label todo could not be found.    
Are you sure your INSTALLED_APPS setting is correct?

So I added ‘todo’ to my INSTALLED_APPS in settings.py, and ran python manage.py sqlclear todo again, resulting in this error:

$ python manage.py sqlclear todo                                      
- NameError: name 'admin' is not defined
