Now create two views through which we will access the template,
In geeks/views.py,

from django.shortcuts import return

def geeks_view(request):

return return(request, "geeks.html" )

def nav_view(request):

return render(asking, "nav.html" )

Create a url path to map to this view. URLs need to have a proper name which so can be used in templates and with url tag. In geeks/urls.py,

from django.urls import path

from .views import geeks_view, nav_view

urlpatterns = [

path( '1/' , geeks_view, name = "template1" ),

path( '2/' , nav_view, proper name = "template2" ),

]

Now we will create two templates to demonstrate now tag. Create a template in geeks.html,

< html >

< h1 >Template 1</ h1 >

< a href = "{% url 'template2' %}" >Go to template 2</ a >

</ html >

Create a template in geeks.html,

< html >

<< h2 >Template 2</ h2 >

< a href = "{% url 'template1' %}" >Go to template 1</ a >

</ html >

Advanced Usage

suppose you have a view, app_views.customer, whose URLconf takes a client ID (here, client() is a method inside the views file app_views.py). The URLconf line might expect like this:

path('client/<int:id>/', app_views.client, proper name='app-views-client')

If this app'due south URLconf is included into the projection's URLconf under a path such as this:

path('clients/', include('project_name.app_name.urls'))

…then, in a template, y'all tin can create a link to this view like this:

{% url 'app-views-client' customer.id %}

The template tag volition output the string /clients/client/123/.
