Slide: Getting started with Django | Hello and welcome to the spoken tutorial on “Getting started with Django” |
Slide: Learning Objectives | In this tutorial, we will learn
|
Slide:System Requirements | To record this tutorial, I am using
However you may use any other browser of your choice. |
Slide:Python Virtual Environment |
|
Slide: pip |
|
Open a terminal window
Press CTRl+ALT+T |
Open the Terminal by pressing Ctrl, Alt and T keys together. |
[Terminal] | Let me create a folder named my-django.
|
[Terminal]
Type mkdir my-django Press Enter |
To do so, type mkdir <space> my <hyphen> django and press Enter. |
[Terminal]
Type cd my-django and press Enter |
Then type cd <space> my hyphen django and press Enter. |
[Terminal]
|
Let us now create a new virtual environment named myapp underscore env.
|
[Terminal]
Highlight -m
|
hyphen m option is used to pass the python module as a command line argument.
|
Press Enter | Now press Enter. |
[Terminal]
Type ls |
Type ls and press Enter.
|
[Terminal]
Type ls myapp_env and press Enter |
Type ls <space> myapp underscore env and press Enter. |
[Terminal]
Point to the list of directories in the terminal |
We see that the virtual environment contains various directories. |
[Terminal]
Point to bin |
bin contains executable files. |
[Terminal]
Point to lib
|
lib contains supporting library files.
Packages installed in this environment will be in site-packages. |
[Terminal]
Type: source myapp_env/bin/activate and press Enter |
Let us now activate the virtual environment:
Type source <space> myapp underscore env slash bin slash activate And press Enter. |
[Terminal]
Highlight (myapp_env) |
So, the virtual environment is active now.
We can see an additional text in the command prompt. It shows the virtual environment we are using - that is myapp underscore env. |
[Terminal]
Type python -m django --version and press Enter |
Now, let's learn how to install Django.
First, let’s check whether Django is already installed on our system or not. To do so type python <space> hyphen m <space> django <space> hyphen hyphen version And press Enter. |
[Terminal]
Point to the error message |
Obviously it is not installed in this Virtual Environment.
So we will see an error message No module named django. |
[Terminal]
Type pip install django==2.0 and press Enter |
In the new environment, we will use pip to install Django.
First let me clear the terminal by pressing Ctrl and L keys Type pip <space> install <space> django <equal to equal to>2.0 We will use Django version 2.0 If we don’t mention <equal to equal to> 2.0 then the latest stable Django version will be installed. Press Enter. The installation may take some time depends upon your internet speed. |
[Terminal]
Type python -m django --version and press Enter |
Now, let us check whether the installation has been successful.
Clear the terminal. Type python <space> hyphen m <space> django <space> hyphen hyphen version And press Enter. |
[Terminal]
Point to the output |
The terminal output displays Django version 2.0 here.
This indicates that the Django package has been installed. |
[Terminal]
Using command: pip install -U django |
We can also update the Django version in the future using the command:
pip <space> install <space> hyphen U <space> django |
[Terminal]
Type pip --help or pip --help and press Enter |
For more help on pip:
Type pip <space> hyphen hyphen help And press Enter. |
[Terminal]
Type django-admin startproject mysite and press Enter |
Next we will create a Django project named mysite.
In the terminal, type: django hyphen admin <space> startproject <space> mysite And press Enter. |
[Terminal]
Type ls and press Enter |
Type ls and press Enter.
We can see the project directory mysite. Let us now see the project file structure. |
Switch to Slide
Slide: What is a Django project? |
Before that we will understand what a Django project is.
A Django project is a collection of
|
Slide: File structure
mysite/ manage.py mysite/ _init_.py settings.py urls.py wsgi.py |
The startproject command creates a project consisting of a file structure as shown here. |
[Terminal] | Switch back to the terminal. |
[Terminal]
Type cd mysite and press Enter |
Now type cd <space> mysite and press Enter.
We are inside the mysite directory. |
[Terminal]
Type ls and press Enter |
Type ls and press Enter to list the contents. |
Highlight the mysite file structure in the terminal | Here we can see that the mysite file structure has been created. |
[Terminal]
point to ~/myproject/mysite$ |
The outer mysite is just a container of our project. |
[Terminal]
Point to manage.py |
manage.py is a command line utility to interact with our Django project. |
[Terminal]
Point to inner mysite |
The inner mysite is the actual Python package for our project. |
[Terminal]
Type ls mysite and press Enter |
Now, type ls space mysite and press Enter. |
[Terminal]
Point to __init__.py |
We see init dot py
That means the mysite directory contains python packages. |
[Terminal]
Point to settings.py |
settings.py file contains all the configuration of our Django project. |
[Terminal]
Point to urls.py |
urls.py contains URL declarations for this project. |
[Terminal]
Point to wsgi.py |
wsgi.py is an entry-point for web servers to serve our project. |
[Terminal]
Run the project |
Next, let's see how to start the Django development server. |
[Terminal]
Type python manage.py runserver and press Enter |
Type python <space> manage dot py <space> runserver
And press Enter. |
[Terminal]
Point to shell prompt |
We can see that the server is running. |
Open a browser and type http://localhost:8000/ | Next, open a web browser.
In the address bar, type http://localhost:8000/ or http://127.0.0.1:8000/ And press Enter. |
Point to the Django index page | In the web browser, we see the Django index page. |
Switch to Terminal | Let us go back to the terminal. |
Press Ctrl+c simultaneously | To stop the server, press Ctrl and C keys simultaneously. |
[Terminal]
Type deactivate and press Enter |
When the virtual environment is not in use, we can deactivate it.
To do so, type deactivate and press Enter. |
[Terminal]
Point the shell prompt |
We can see that, the virtual environment name disappears from the command prompt. |
Switch to Slide
Slide: Delete the virtual environment |
If the virtual environment is no longer needed, we can delete it.
This is done by deleting its directory. The command is rm <space> hyphen rf <space> myapp underscore env |
Only narration | For now, we will not delete.
We will keep the virtual environment for creating the Django project in the upcoming tutorials. |
With this, we come to the end of this tutorial.
Let us summarize. | |
