This is an application that provides tools for displaying QR codes on your [Django](https://www.djangoproject.com/) site.



This application depends on the [Segno QR Code generator](https://pypi.org/project/segno/) library.



This app makes no usage of the Django models and therefore do not use any database.



Only Python >= 3.10 is supported.



## Features



* Generate QR codes as embedded SVG or PNG images in HTML templates.

* Customize QR codes with various parameters (size, error correction, border, etc.).

* Generate URLs for QR code images.

* Support for specific application QR codes (e.g., contact info, Wi-Fi config).

* Cache QR code images for performance.

* Secure QR code image serving with URL protection and user authentication.



## Installation



### Binary Package from PyPi

In order to use this app in a Django project, the simplest way is to install it from [PyPi](https://pypi.python.org/pypi/django-qr-code):

```bash

pip install django-qr-code

```



### From the Source Code

In order to modify or test this app you may want to install it from the source code.



Clone the [GitHub repository](https://github.com/dprog-philippe-docourt/django-qr-code) and install dependencies:

```bash

git clone https://github.com/dprog-philippe-docourt/django-qr-code

pip install -r requirements.txt -r requirements-dev.txt

python manage.py collectstatic --no-input

```



## Usage

Start by adding `qr_code` to your `INSTALLED_APPS` setting like this:

```python

INSTALLED_APPS = (

    # ...,

    'qr_code',

)

```



You need to load the tags provided by this app in your template with:

```htmldjango

{% load qr_code %}

```



The source code on [GitHub](https://github.com/dprog-philippe-docourt/django-qr-code) contains a simple demo app. Please check out the [templates folder](https://github.com/dprog-philippe-docourt/django-qr-code/tree/master/qr_code_demo/templates/qr_code_demo) for an example of template, and the [setting](https://github.com/dprog-philippe-docourt/django-qr-code/tree/master/demo_site/settings.py) and [urls](https://github.com/dprog-philippe-docourt/django-qr-code/tree/master/demo_site/urls.py) files for an example of configuration and integration.



### Example: Inline QR Code



Generate a simple QR code:



```htmldjango

{% qr_from_text "Hello World!" size="T" %}

```

### Example: URL QR Code



Generate a URL for a QR code image:



```htmldjango

Hello World!

```



### Advanced Usage of Tags



Refer to the [official documentation for tags](https://django-qr-code.readthedocs.io/latest/pages/template-tags.html) for more detailed information and advanced usage examples.



### Demo Application

If you want to try this app, you may want to use the demo application shipped alongside the source code.



Get the source code from [GitHub](https://github.com/dprog-philippe-docourt/django-qr-code), follow the [installation instructions](#from-the-source-code) above, and run the `runserver` command of Django:

```bash

python manage.py runserver

```

The demo application should be running at .



If you have [Docker Compose](https://docs.docker.com/compose/) installed, you can simply run the following from a terminal (this will save you the burden of setting up a proper python environment):

```bash

cd scripts

./run-demo-app.sh

```

The demo application should be running at .



## Generating Image Object Representing a QR Code



If you do not want to use Django tags for rendering QR code in a template, you can simply use the API in your code. For instance, `qr_code.qrcode.maker.make_qr_code_image` will return bytes representing an image according to the image_format passed in the `qr_code_options` parameter.



Refer to the [official API documentation](https://django-qr-code.readthedocs.io/latest/pages/api.html) for more detailed information.



## Testing

Get the source code from [GitHub](https://github.com/dprog-philippe-docourt/django-qr-code), follow the [installation instructions](#from-the-source-code) above, and run the `test` command of Django:

```bash

python manage.py test

```

This will run the test suite with the locally installed version of Python and Django.



If you have [Docker Compose](https://docs.docker.com/compose/) installed, you can simply run the following from a terminal (this will save you the burden of setting up a proper python environment):

```bash

cd scripts

./run-tests.sh

```

This will run the test suite with all supported versions of Python and Django. The test results are stored within `tests_result` folder.
