django.urls.exceptions.NoReverseMatch at /home/

I have problem when I visit localhost:8000/home:

Powershell: django.urls.exceptions.NoReverseMatch: Reverse for ‘register’ not found. ‘register’ is not a valid view function or pattern name.

html:

<section>
    <nav class="navbar navbar-expand-lg bg-dark navbar-dark ">

      <div class="container-fluid justify-content-center">

Error:

>Solution :

You made a typo, it is users-registration and not user-registration :

<li class="nav-item"><a class="nav-link" href="{% url 'accounts:users-registration' %}">Register</a></li>
