# :zap: Python Django QRCode
* Python-Django app to create QR (Quick Response) codes

## :books: General info
* Django framework admin dashboard lets user specify website address, although any text entry up to 200 chars will be accepted. This text is converted into a QR code and displayed using the `qrcode` Python library function.
* QR codes saved to a media file on the hard drive - not in the project file.
## :camera: Screenshots
## :signal_strength: Technologies
* [Python v3](https://www.python.org/) programming language
* [Django v3](https://www.djangoproject.com/) server-side web framework
* [PyPI library package: qrcode v6](https://pypi.org/project/qrcode/) Pure python QR Code generator
## :floppy_disk: Setup
* [Install Python](https://docs.python-guide.org/starting/installation/)
* [Install pip](https://docs.python-guide.org/dev/virtualenvs/#installing-pipenv)
* [Install Django](https://docs.djangoproject.com/en/3.1/howto/windows/) by typing `pip install Django`
* Run `django-admin startproject qrcode_proj` to create a new project [ref. docs](https://docs.djangoproject.com/en/3.1/intro/tutorial01/)
* Open `qrcode_proj` in VS Code
* Run `python manage.py startapp websites` to create Python module
* Add code
* Run `pip freeze` to see list of modules installed. [Ref. Docs](https://pip.pypa.io/en/stable/reference/pip_freeze/)
* Run `python manage.py makemigrations` for changes to models etc.
* Run `python manage.py migrate` to migrate the migration files.
* To add a superuser run `python manage.py createsuperuser --username=joe --email=joe@example.com` [Ref. Docs](https://docs.djangoproject.com/en/3.1/topics/auth/default/) and log into admin panel
* Run `python manage.py runserver` to run server on port 8000. A refresh is needed after any code changes
## :computer: Code Examples
* extract from `websites/models.py` - saves QR code image with website name as a PNG (Portable Network Graphic) which is the best format to use as it gives a good quality image in a small file size
```python
def save(self, *args, **kwargs):
qrcode_img = qrcode.make(self.name)
canvas = Image.new('RGB', (290, 290), 'white')
draw = ImageDraw.Draw(canvas)
canvas.paste(qrcode_img)
fname = f'qr_code-{self.name}.png'
buffer = BytesIO()
canvas.save(buffer, 'PNG')
self.qr_code.save(fname, File(buffer), save=False)
canvas.close()
super().save(*args, **kwargs)
```
