Hi, I'm am trying to follow along with the tutorial, but keep getting this error when I migrate the models. Here is my models.py file for the polls app:
from django.db import models class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') class Choice(models.Model): question = models.ForeignKey(Question) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) Then, when I use the makemigrations and migrate commands, I get this error: Operations to perform: Apply all migrations: auth, admin, sessions, contenttypes, polls Running migrations: Applying polls.0001_initial...Traceback (most recent call last): File
