I can't figure out what is problem :

django.core.urlresolvers.NoReverseMatch: Reverse for 'performer' with arguments '()' and keyword arguments '{'pk': ''} ' not found. 1 pattern(s) tried: ['songs/performer/(?P<pk>\d+)/$']

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)
    performer = models.ForeignKey(Performer)
    duration = models.IntegerField(default=0)

    def __str__(self):
        return '{} by {}'.format(self.title, self.artist)
from django.shortcuts import render, get_object_or_404
from .models import Song, Performer

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

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

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

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

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