Django is a powerful web framework that makes it easy to create complex web applications. One of the most powerful features of Django is its URL routing system, which allows you to easily map URLs to views and other resources. In this tutorial, we'll show you how to use URL routing in Django.
The first step is to install Django. You can do this using the pip package manager. To install Django, open a terminal window and type the following command:
pip install djangoThis will install the latest version of Django. Once the installation is complete, you can verify that Django is installed by typing the following command:
python -m django --versionThis will print out the version of Django that is installed. If everything is working correctly, you should see something like this:
Django 2.2.7Now that Django is installed, we can create a project. To do this, we need to create a directory for our project and then use the django-admin command to create the project. To create a directory for our project, open a terminal window and type the following command:
mkdir myprojectThis will create a directory called myproject. Now we can use the django-admin command to create our project. To do this, type the following command:
django-admin startproject myprojectThis will create a directory called myproject with the necessary files and directories for our project. Now we can move into the project directory and start working on our project.
The next step is to create an app. An app is a collection of code that is used to perform a specific task. To create an app, we need to use the django-admin command. To do this, type the following command:
django-admin startapp myappThis will create a directory called myapp with the necessary files and directories for our app. Now we can move into the app directory and start working on our app.
Now that we have created our app, we need to add it to our project. To do this, we need to edit the settings.py file in our project directory. Open the settings.py file and add the following line:
INSTALLED_APPS = [ ... 'myapp',]This will add our app to the list of installed apps. Now we can start using our app in our project.
Now that we have added our app to our project, we need to create a URL pattern. A URL pattern is a regular expression that is used to match a URL and map it to a view. To create a URL pattern, we need to edit the urls.py file in our project directory. Open the urls.py file and add the following line:
urlpatterns = [ ... path('myapp/', include('myapp.urls')),]This will add our app's URL patterns to the list of URL patterns. Now we can start creating our app's URL patterns.
Now that we have created our URL pattern, we need to create a view. A view is a function that is used to handle a request and return a response. To create a view, we need to edit the views.py file in our app directory. Open the views.py file and add the following code:
from django.http import HttpResponsedef myview(request): return HttpResponse('Hello, World!')This will create a view called myview that will return a response with the text "Hello, World!". Now we can map our view to a URL pattern.
Now that we have created our view, we need to create a template. A template is a file that contains HTML code that is used to render a response. To create a template, we need to create a directory called templates in our app directory. Then we need to create a file called mytemplate.html in the templates directory. Open the mytemplate.html file and add the following code:
<html> <head> <title>My Template</title> </head> <body> <h1>Hello, World!</h1> </body></html>This will create a template that will render a response with the text "Hello, World!". Now we can map our template to our view.
In this tutorial, we have shown you how to use URL routing in Django. We have installed Django, created a project, created an app, added the app to the project, created a URL pattern, created a view, and created a template. With these steps, you should now be able to use URL routing in Django.
