[Fixed]-Best way of linking to a page in Django

Django has updated urlpatterns to take ‘path’ instead of using url so it’s become much more efficient. You don’t have to use regex anymore

from django.urls import path
from . import views

urlpatterns=[
    path('', views.index , name='index'),
    path('blog/', views.blog , name='blog'),]

Then in templates, you can use template tagging

<a href="{% url 'index' %}">Index</a>
<a href="{% url 'blog' %}">Blog</a>

If you have multiple apps, you can tag it as follows. For example, if this is under ‘post’ app:

In post app urls.py:

from django.urls import path
from . import views

app_name = 'post'
urlpatterns=[
    path('', views.index , name='index'),
    path('blog/', views.blog , name='blog'),]

in the project urls.py:

from django.urls import path, include

urlpatterns=[
path('post/', include('post.urls'),]

In templates, you do as following:

<a href="{% url 'post:index' %}">Index</a>
<a href="{% url 'post:blog' %}">Blog</a>

Just use the same label {% url 'index' %}.
You may use each name in urls.py to link to the url.

urls.py

url(r'^archive/$', 'mysite.views.archive',name='archive'),
url(r'^about/$', 'mysite.views.about',name='about'),
url(r'^contact/$', 'mysite.views.contact',name='contact'),

template

<a href="{% url 'about' %}">About</a>
<a href="{% url 'contact' %}">Contact</a>

If you have many apps, use namespace
https://docs.djangoproject.com/en/dev/topics/http/urls/#url-namespaces-and-included-urlconfs

Use the below syntax:

<a href="{% url 'cart' %}" > Cart page </a>

Where URL ‘cart’ is the name field in your app URL pattern.

urlpatterns = [
    #Leave as empty string for base url
    path('', views.shop, name="store"),
    path('cart/', views.cart, name="cart"),--------------------->
    path('checkout/', views.checkout, name="checkout"),
    path('shop/',views.shop, name="shop"),

]

Create a new URL in the same format and give that name instead of index.

Eg:

url(r'^$', 'index', name='index'),
url(r'^new/page/$', 'new', name='new_page'),

{% url 'new_page' %}

Example:

urlpatterns = patterns('',
                       url(r'^$', views.index, name='index'),
                       url(r'^about/$', views.about', name='about'),
)

Now, in the html template rendered by your views.index you can have:

<a href ="{% url 'about' %}">about</a>
