Test variable not getting data from database

Using Django
1

I can’t figure out why the latest_blogs_list continues to print as blank even though I just added a post to the database, hence making the test return false. As far as I can tell, my syntax is flawless, I’ve gone over it with several fine-toothed combs and found nothing wrong. it just returns empty.

I checked that the post is being created, and it’s definitely there, but it’s not being added to the list.

# tests.py
def test_latest_blogs_list_with_one_post(self):
        response = self.client.get(reverse(index))

        User.objects.create(password="12345", is_superuser=False, is_staff=False, is_active=True,username="testuser", first_name="test", last_name="user",   
            email="guineveremayberry@gmail.com", date_joined=datetime.now())
        post_author = User.objects.get(username="testuser")
        post_content = "This is a test. This is only a test. This test will tell us whether or not latest_blogs_list will display on the home page when there is only one post."

        post1 = Post.objects.create(title="test1", slug="test1", author=post_author, content=post_content, status=1)
        print(response.context['latest_blogs_list'])

        self.assertEqual(response.status_code, 200)
        self.assertContains(response, post1.title)
        self.assertQuerysetEqual(response.context['latest_blogs_list'], [post1])

<!--base.html which is extended by index.html-->
<h4>Recent Blogs</h4>
                {% if latest_blogs_list %}
                    {% for post in latest_blogs_list %}
                    <p><a href="">{{ post.title }}</a></p>
                    {% endfor %}
                {% else %}
                    <p>No posts are available.</p>
                {% endif %}

# models.py
STATUS = (
    (0, "Draft"),
    (1, "Publish")
)

class Post(models.Model):
    title = models.CharField(max_length=200, unique=True)
    slug = models.SlugField(max_length=200,unique=True)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    updated_on = models.DateTimeField(auto_now=True)
    content = models.TextField()
    created_on = models.DateTimeField(auto_now_add=True)
    status = models.IntegerField(choices=STATUS, default=0)

    class Meta:
        ordering = ['-created_on']

    def __str__(self):
        return self.title

You’re doing things out of order here.

You’re getting your response before you’re adding the post.

The response you’re getting in the line:

is a response based on the data in the database at the time that it is called. This response object is not an “active entity” that will update itself automatically as other code executes.

So you probably want to move that line to a location after:
post1 = Post.objects.create(title="test1", slug="test1", author=post_author, content=post_content, status=1)
