django NoReverseMatch Exception


django NoReverseMatch Exception



I'm getting the following error while using hyperlink in Django.



Error:



django.urls.exceptions.NoReverseMatch: 'mywebapp' is not a registered namespace


django.urls.exceptions.NoReverseMatch: 'mywebapp' is not a registered namespace



mywebapp/template/about.html ..


<body>
<a href="{% url 'mywebapp:home' %}">Click here</a>
Hello World!!!<p>Today is {{today}}</p>





mywebapp/template/home.html ..


<h4>Homepage.</h4>



settings.py ..


INSTALLED_APPS =
[
...
'mywebapp'#new
...
]





Make sure you have app_name='home' in your mywebapp/urls.py. If that doesn’t solve the problem, then you need to show your urls.py.

In you urls.py of the mywebapp app, make sure you have:


urls.py


mywebapp


app_name = 'mywebapp'

urlpatterns = [
re_path(r'REGEX_HOME', YOUR_HOME_VIEW, name='home'),
# or if you're not using regex
# path('HOME_PATH', YOUR_HOME_VIEW, name='home'),
# for Django 1.11
# url(r'REGEX_HOME', YOUR_HOME_VIEW, name='home'),
]



Substitute REGEX_HOME and YOUR_HOME_VIEW with your own values.


REGEX_HOME


YOUR_HOME_VIEW
