Django1.8 Updating the database

Recently in a Web site, the expansion of the user needs to synchronize changes to the database (I use the sqlite3), the Internet to find more than N, online are the same, wandering, it is annoying!!
I don't know if it's 1.8. This feature, update data table only need to execute

python manage.py makemigrations

The message will be displayed at this time

for‘registration‘:  0002_userprofile.py:    Create model UserProfile

UserProfile is my extension to user, which has been detected automatically.
And then execute

python manage.py migrate

OK, there is no need to remove the database reload or manually add!
