Why am I getting "django.db.utils.OperationalError: no such table: songs_performer"?

What's wrong with my code?

songs/models.py 
from django.db import models

class Performer(models.Model):
    name = models.CharField(max_length=255)

    def __str__(self):
        return self.name


class Song(models.Model):
    title = models.CharField(max_length=255)
    artist = models.CharField(max_length=255)
    length = models.IntegerField(default=0)
    performer = models.ForeignKey(Performer)

    def __str__(self):
        return "{} by {}".format(self.title, self.artist)
songs/views.py 
from django.shortcuts import get_object_or_404, render

from .models import Performer, Song


def song_list(request):
    songs = Song.objects.all()
    return render(request, 'songs/song_list.html', {'songs' : songs})

def song_detail(request, pk):

    song = get_object_or_404(Song, pk=pk)
    return render(request, 'songs/song_detail.html', {'song' : song})

def performer_detail(request, pk):
    performer = get_object_or_404(Performer, pk=pk)
    return render(request, 'songs/performer_detail.html', {'performer' : performer})
songs/templates/songs/performer_detail.html 
{% extends 'base.html' %}

{% block title %}{{ performer }}{% endblock %}

{% block content %}
<h2>{{ performer }}</h2>

  {% for song in performer.song_set.all %}
      {% if song.performer.pk == performer.pk: %}
        {{ song }}
      {% endif%}
  {% endfor %}
{% endblock %}

It looks like you have an extra colon (":") in your template:

{% block content %}
<h2>{{ performer }}</h2>

  {% for song in performer.song_set.all %}
      {% if song.performer.pk == performer.pk %}  {# <-- remove trailing colon #}
        {{ song }}
      {% endif%}
  {% endfor %}
{% endblock %}
