This is the most common error I get but the common reasons for getting this error only resolve it about half the time. In this case, I somehow broke all 22 tests for my home app without making any changes to the tests or the view.

```auto
#home.views.py

def index(request):
    latest_blogs_list = Post.objects.filter(status=1).order_by('-created_on')[:3]
    latest_projects_list = Projects.objects.order_by('-completion_date')[:3]
    extended_projects_list = Projects.objects.order_by('-completion_date')[:10]
    context = {
        'latest_blogs_list': latest_blogs_list,
        'latest_projects_list': latest_projects_list,
        'extended_projects_list': extended_projects_list,
    }
    return TemplateResponse(request, "home/index.html", context)

As far as I know, the error began when I got rid of base.html and instead divided it into desktop\_nav, mobile\_nav, hero, and footer.html. The reason I did this was because django wanted to get the css links from base.html and I wanted to put the css links in the main templates. The tests all relate to listing blog posts and completed projects in the header and footer:

```auto
#this is just a sample, all of the tests give the same error

from .views import index

def test_latest_blogs_list_with_two_posts(self):
        #creates a user and labels it as an author
        User.objects.create(password="12345", is_superuser=False, is_staff=False, is_active=True,username="gemivere", first_name="Guinevere", last_name="Mayberry",   
            email="guineveremayberry@gmail.com", date_joined=datetime.now())
        post_author = User.objects.get(username="gemivere")

        #creates two blog posts
        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)
        post2 = Post.objects.create(title="test2", slug="test2", author=post_author, content=post_content, status=1)

        #tests
        response = self.client.get(reverse(index))

        self.assertEqual(response.status_code, 200)
        self.assertContains(response, post1.title)
        self.assertContains(response, post2.title)
        self.assertQuerysetEqual(response.context['latest_blogs_list'], [post2, post1])

```

The error I get is “django.urls.exceptions.NoReverseMatch: Reverse for ‘home.views.index’ not found. ‘home.views.index’ is not a valid view function or pattern name.”

I’m assuming the error is being flagged for this line:

> [@gemivere](#):
>
> ` response = self.client.get(reverse(index))`

What is the value of `index` being used here? I don’t see it being set in your test.

it’s the imported view, from .views import index

Ok, quoting from the example code in the docs for [reverse](https://docs.djangoproject.com/en/4.0/ref/urlresolvers/#reverse):

```auto
# passing a callable object
# (This is discouraged because you can't reverse namespaced views this way.)

```

Without knowing more about how your apps are configured or urls are defined, I can’t say whether this is the problem affecting you or not.

Either way, I’d follow the general suggestion to use the `name` attribute of the url and reverse _it_.

tried that, and still the same error.

```auto

app_name = "home"

urlpatterns = [
    path('', index, name='home'),

        post_author = User.objects.get(username="gemivere")
