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

from zipfile import ZipFile
from django.template import Context
from django.template.loader import get_template
class TemplateZipFile(ZipFile, object):
def __init__(self, file, template_root=None, *args, **kwargs):
self.template_root = template_root
return super(TemplateZipFile, self).__init__(file, *args, **kwargs)
def add_template(self, template_name, filename=None, context=None, compress_type=None):
if compress_type is not None:
if compress_type != self.compress_type and sys.version_info < (2, 7):
raise "Python2.7 is required for individual file compression."
if context is None:
c = Context({})
else:
c = Context(context)
if self.template_root is not None:
template_name = self.template_root + template_name
template = get_template(template_name)
render = template.render(c)
if filename is None:
if self.template_root is not None:
arc_filename = template_name.split(self.template_root)[1]
else:
arc_filename = template_name.split('/')[-1]
if compress_type is not None:
self.writestr(arc_filename, render, compress_type)
else:
self.writestr(arc_filename, render)
