Django MySQL error on migrate
Question:
I’m trying to follow the “Writing your first Django app” tutorial on the Django website and I’m stuck at part 2 about the database stuff.
I’m running Ubuntu 14.04 and Python 3.4.
I’ve installed MySQL and the Python MySQL libraries and made a database in MySQL called testdb but when trying to run the command
python3 manage.py migrate
I get the following error:
server1:~/Desktop/app/mysite$ python3 manage.py migrate

My database setup in django looks like this
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'testdb',
'USER': 'root',
'PASSWORD': 'xxxx',
'HOST': '127.0.0.1',
}
}
The only changes I made to the base django project template was adding an app, some url maps and making the change to the database settings and switching the backend to sqlite works fine.
Any help with figuring this out would be awesome, thanks.
Edit: Here’s my installed apps, urls and I don’t have any models yet.

Answers:
The problem seems to have been a bad MySQL connector. Found a good one from this post.
Had to do a
sudo apt-get install libmysqlclient-dev
then
sudo pip3 install mysqlclient
Make sure that you have deleted the migration files in all your applications at first
then run make migrations in each app you have
python manage.py makemigrations <appname_1 # till appname_n>
then
python manage.py migrate
