5,190 PointsTDD: can't pass final challenge
Just having trouble with the final challenge. Also, to complicate things I can't get the command 'python manage.py tests' to run the unit tests in workspaces. So I have no idea which test is failing, haha!
from django.db import models
# Write your models here
class Song(models.Model):
title = models.CharField(max_length=255)
artist = models.CharField(max_length=255)
performer = models.ForeignKey("Performer")
length = models.IntegerField(default=0)
def __str__(self):
return self.title + "by" + self.artist
class Performer(models.Model):
name = models.CharField(max_length=255)
def __str__(self):
return self.name
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})
{% 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 %}

{% extends 'base.html' %}
{% block title %}{{ performer }}{% endblock %}
{% block content %}
<h2>{{ performer }}</h2>
{% for song in performer.song_set.all %}
<{{ song.title }}> by <{{ song.artist }}> # line with the error
{{ song.title }} by {{ song.artist }}
{% endfor %}
{% endblock %}

(not plural).
To run individual tests specify its name or to stop on first failure use the switch --failfast
. Other test
options can be listed using --help
:
$ python manage.py test --help
usage: manage.py test [-h] [--version] [-v {0,1,2,3}] [--settings SETTINGS]
[--pythonpath PYTHONPATH] [--traceback] [--no-color]
[--noinput] [--failfast] [--testrunner TESTRUNNER]
[--liveserver LIVESERVER] [-t TOP_LEVEL] [-p PATTERN]
[-k] [-r] [-d]
[test_label [test_label ...]]
Discover and run tests in the specified modules or the current directory.
positional arguments:
test_label Module paths to test; can be modulename,
modulename.TestCase or modulename.TestCase.test_method
optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
-v {0,1,2,3}, --verbosity {0,1,2,3}
Verbosity level; 0=minimal output, 1=normal output,
2=verbose output, 3=very verbose output
--settings SETTINGS The Python path to a settings module, e.g.
"myproject.settings.main". If this isn't provided, the
DJANGO_SETTINGS_MODULE environment variable will be
used.
--pythonpath PYTHONPATH
A directory to add to the Python path, e.g.
"/home/djangoprojects/myproject".
--traceback Raise on CommandError exceptions
--no-color Don't colorize the command output.
--noinput Tells Django to NOT prompt the user for input of any
kind.
--failfast Tells Django to stop running the test suite after
first failed test.
--testrunner TESTRUNNER
Tells Django to use specified test runner class
instead of the one specified by the TEST_RUNNER
setting.
--liveserver LIVESERVER
Overrides the default address where the live server
(used with LiveServerTestCase) is expected to run
from. The default value is localhost:8081.
-t TOP_LEVEL, --top-level-directory TOP_LEVEL
Top level of project for unittest discovery.
-p PATTERN, --pattern PATTERN
The test matching pattern. Defaults to test*.py.
-k, --keepdb Preserves the test DB between runs.
-r, --reverse Reverses test cases order.
-d, --debug-sql Prints logged SQL queries on failure.

5,190 PointsYeah, I figured out the test command but I get the following error:
File "/usr/local/pyenv/versions/3.5.0/lib/python3.5/site-packages/django/db/backends/sqlite
3/base.py", line 323, in execute
return Database.Cursor.execute(self, query, params)
django.db.utils.OperationalError: no such table: songs_song
It seems the error is in the database or base.py file. I am using workspaces to complete the challenge so I don't think I can access either file. There may be more errors in the code but this one keeps failing the test command.
