Not for sure what i am doing wrong..HELP!

Copy and paste your models, views, and performer template from Workspaces into the correct files below.

songs/models.py 
from django.db import models

class Song(models.Model):
    title = models.CharField(max_length=30)
    artist = models.CharField(max_length=30)
    performer = models.ForeignKey('Performer')
    length = models.PositiveIntegerField(default=0)

def __str__(self):
     return '{} by {}'.format(self.title, self.artist)


class Performer(models.Model):
    name = models.CharField(max_length=30)

def __str__(self):
     return self.name
songs/views.py 
from django.shortcuts import get_object_or_404, render
from .models import Song, Performer

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


def song_detail(request, pk):
    song = get_objects_or_404(Song, pk=pk)
    return render(request, 'songs/song_detail.html', {'song': song})


def performer_detail(request, pk):
    performer = get_objects_or_404(Performer, pk=pk)
    songs = Song.objects.filter(performer=performer)
    return render(request, 'songs/performer_detail.html', {'performer': performer})
songs/templates/songs/performer_detail.html 
def performer_detail(request,pk):
  performer = get_object_or_404(Performer,pk=pk)
  return render(request,'songs/performer_detail.html',{'performer':performer})



{% extends 'base.html' %}

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

{% block content %}
<h2>{{ performer }}</h2>
{% for song in performer.song_set.all %}
    {{ song.title }} by {{ song.artist }}
{% endfor %}
{% endblock %}

You are getting pretty close, don't let the syntax errors frustrate you -- in most python environments we have better syntax parsing than in the challenge environment.

Comments:

  1. In models.py, the indentation of def __str__(self): needs to be fixed to make both of them part of the class

  2. In views.py, you pluralized "Songs.objects.all()" it should be Song.objects.all() also... you pluralized the word "objects"` twice

songs = Songs.objects.all() # error, should be Song.objects.all()

song = get_objects_or_404(Song, pk=pk) # error should be get_object_or_404()

performer = get_objects_or_404(Performer, pk=pk) # error should be get_object_or_404()
  1. this may just be a typesetting thing, but the "def performer_detail(request,pk):" block is accidentally duplicated in the performer_detail.html. It should only be present in views.py
