Getting started with Django
Before you can use Django you need to install Django in the system. To install django, run this command 'pip install django' or ‘python -m pip install Django’ in the anaconda command prompt. After the installation is successful we can build the django web application.
Here we created Simple web application project print ‘Hello World!’
First set the path to the folder that will contain all the files in your project. After that, for creating the django project, run the following command on anaconda command prompt. ‘django-admin startproject mysite’ Note : mysite is the project name. This will create a new directory. If cd into this new directory you’ll see another directory called mysite and a file called manage.py.
Once the django project is created, first change the directory to mysite. Then start the server by using the given command to check the set up was successful. ‘python manage.py runserver’.
After that, copy the link and run it on the browser and you should see the following.
In this step create a django application using this command ‘python manage.py startapp hello_world’. This command will create a folder ‘hello_world’ and five python files in that folder.
Create a view. Views in Django are a collection of functions or classes inside the views.py file in your app directory. In this we have defined a view function called hello_world(). This data will display on the web browser.
The final step is to hook up URLs so that we can visit the page we have just created. We need to include a URL configuration for the hello_world app. Inside mysite/urls.py, add the following:
Inside hello_world/urls.py, we need to import the path object as well as our app’s views module. Then create a list of URL patterns that correspond to the various view functions.
Now, when you start the server and visit localhost:8000/hello_word, you should be able to see the message.
