django testing the article detail view.

How do you pass the pk to the reverse function?

articles/tests.py 
import datetime

from django.core.urlresolvers import reverse
from django.test import TestCase

from .models import Article, Writer

class ArticleDetailViewTestCase(TestCase):
    '''Tests for the Article detail view'''

    def setUp(self):
        self.writer = Writer.objects.create(
            name='Kenneth Love',
            email='kenneth@teamtreehouse.com',
            bio='Your friendly, local Python teacher'
        )
        self.article = Article.objects.create(
          writer=self.writer,
          headline='Article 0',
          content='Something about 0',
          publish_date=datetime.datetime.today()
        )

    def test_detail_template(self):
        '''Make sure the `articles/article_detail.html` template is used'''
        resp = self.client.get(reverse('articles:detail', self.article}))
        self.assertEqual(resp.status_code,200)
        self.assertTemplateUsed(response,'articles/article_detail.html')


    def test_detail_template_writer(self):
        '''Make sure the article writer's name is in the rendered output'''
articles/templates/articles/article_detail.html 
{% extends 'base.html' %}

{% block content %}
<h1>{{ article.title }}</h1>
<time>{{ article.publish_date }}</time>
<p>By {{ article.writer.name }}</p>
{{ article.content }}
{% endblock %}

Aside on cleaning up formatting:

  • The python formatting is lost above due backticks within a triple-backtick code block.
  • The ' ' come from Cntl-M end of line markers leftover from the EOL translation from Windows EOL to Linux EOL.

#so...
resp = self.client.get(reverse('articles:detail', kwargs={'pk': self.article.pk}))

#and use resp not response in your self.assertTemplateUsed so ..

self.assertTemplateUsed(resp,'articles/article_detail.html')

[edit format -cf]

Include .name

 def test_detail_template_writer(self):
        '''Make sure the article writer's name is in the rendered output'''
        resp=self.client.get(reverse('articles:detail',kwargs={'pk': self.article.pk}))
        self.assertContains(resp,self.article.writer.name) #include .name

Thanks that worked. Although my second part of the challenge now errors out with 'assertContains not used' this is what I am done

 def test_detail_template_writer(self):
        '''Make sure the article writer's name is in the rendered output'''
        resp=self.client.get(reverse('articles:detail',kwargs={'pk': self.article.pk}))
        self.assertContains(resp,self.article.writer)

I suspect this is a bug in the objective. It works if you move the response to setUp():

import datetime

from django.core.urlresolvers import reverse
from django.test import TestCase

from .models import Article, Writer

class ArticleDetailViewTestCase(TestCase):
    '''Tests for the Article detail view'''

    def setUp(self):
        self.writer = Writer.objects.create(
            name='Kenneth Love',
            email='kenneth@teamtreehouse.com',
            bio='Your friendly, local Python teacher'
        )
        self.article = Article.objects.create(
          writer=self.writer,
          headline='Article 0',
          content='Something about 0',
          publish_date=datetime.datetime.today()
        )
        self.response = self.client.get(reverse('articles:detail', kwargs={'pk': self.article.pk}))

    def test_detail_template(self):
        '''Make sure the `articles/article_detail.html` template is used'''
        self.assertTemplateUsed(self.response, 'articles/article_detail.html')

    def test_detail_template_writer(self):
        '''Make sure the article writer's name is in the rendered output'''
        self.assertContains(self.response, self.article.writer.name)
