A class-based view that generated pdfs using WeasyPrint

I combined all the forks lying around.

Then I found out weasyprint does not support 'rem' units. :( So I stopped working on it.

Then I added 'rem' support. :D And worked a little more on the mixins.

Use PDFTemplateView as class based view base class or the just the mixin PDFTemplateResponseMixin on a TemplateView (or subclass thereof).

from django.conf import settings
from django.views.generic import DetailView

from django_weasyprint import PDFTemplateResponseMixin


class MyModelView(DetailView):
    model = MyModel
    template_name = 'mymodel.html'


class MyModelViewPrintView(PDFTemplateResponseMixin, MyModelView):
    stylesheets = [
        settings.STATIC_ROOT   "css/app.css",
    ]
