Running Django server (Python 3.4)

Question

I tried today to install Django for Python 3.4. I managed to create a project but when I try to run the server with python manage.py runserver (I'm on Windows 7), I get an error :

Performing system checks...

You have unapplied migrations; your app may not work properly until they are applied.
Run 'python manage.py migrate' to apply them.

And I can't access my server. How can I run the server ? Thanks,

• Ozan Tabak: Hi, did you modify your database or models.py after creating the project? If so try to remove your database and let django create it from scratch.
• joel goldstick: The first message says that you have unapplied migrations. Do that first
• Ozan Tabak: On the other hand this pretty much looks like an encoding problem on your settings file, sdz.settings. I think you copied from a tutorial or somewhere, check every field like "hostname" and try to rewrite it.
• iSteelZ: I didn't modify anything, and I tried removing the DB. Still not working. I did the migrations, but nothing. I didn't copied it, I just did django-admin.py startproject sdz.

Answer 1

Run the following command:

manage.py migrate

This will create your tables in your database, then try running your server.

Answer 2

Okay I got it, it was pretty dumb, I just had non-ASCII characters in my hostname. Now it works perfectly !
