I am new to django, Help me to fix this issue?

回答1:

I encountered this problem as well. I was going through the PyCharm Django guide. I fixed this by deleting my sqlite database file and running syncdb again. I don't know why it didn't work the first time, but it works now.

Also, it's probably worth downloading the SQLite Database Browser so that you can see the actual structure of your SQLite database. For this issue, you're interested in the django_site table. After I deleted my database file and reran syncdb, there was one row in this table.

回答2:

This problem occurs because the first time that you executes python manage.py syncdb. isn't specified a main user. To solve it, delete all tables created by django in data base (with mysql, postgresql..) or delete the database.db (with sqlite3), Then run python manage.py syncdb one more time
