TemplateZipFile is a class for creating ZipFiles out of Django templates.

Usage example:

from zipfile import ZIP_DEFLATED
from django_zipfile import TemplateZipFile

def myview(request, object_id):
    obj = get_object_or_404(MyModel, pk=object_id)
    context = {
        'object': obj
    }
    response = HttpResponse(mimetype='application/octet-stream')
    response['Content-Disposition'] = 'attachment; filename=myfile.zip'
    container = TemplateZipFile(response, mode='w', compression=ZIP_DEFLATED, template_root='myapp/myzipskeleton/')

    container.add_template('mimetype')
    container.add_template('META-INF/container.xml')
    container.add_template('chapter1.html', context=context)

    container.close()
    return response
