Django template tag for generating QR codes using segno

Thanks for using Segno ;)
I added a hint to your project in the docs: https://segno.readthedocs.io/en/latest/web-development.html#django
This code in segno_qr.py
creates a complete XML document with XML declaration and namespaces:
svg = BytesIO()
qr.save(svg, 'svg', scale=size, dark=dark, light=light)
result = svg.getvalue().decode('utf8')
return mark_safe(result)
I suggest to omit the XML declaration and the SVG namespace since the latter is already known by HTML5 browsers.
Basically you can reduce the code to
result = qr.svg_inline(scale=size, dark=dark, light=light)
return mark_safe(result)
The method svg_inline
omits the XML declaration and the namespace declaration automatically and returns the SVG as string.
svg_inline was added in 1.2.0
If you don't want to rely on svg_inline, I suggest to change the code as follows:
svg = BytesIO()
qr.save(svg, 'svg', xmldecl=False, svgns=False, nl=False, scale=size, dark=dark, light=light)
result = svg.getvalue().decode('utf8')
return mark_safe(result)
