Description:

djangozipfile 0.4.0

A subclass of zipfile.Zipfile that works with Django templates.
Usage:
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.write_template('mimetype')
container.write_template('META-INF/container.xml')
container.write_template('chapter1.html', context=context)

container.close()
return response
You can also specify multiple roots for your templates:
container = TemplateZipFile(response, mode='w', compression=ZIP_DEFLATED, template_root=['myapp/myzipskeleton/override/', 'myapp/myzipskeleton/default/'])
as well as multiple templates when you add files:
container.write_template(['override.html', 'default.html'], filename="chapter1.html")
TemplateZipFile will look for templates in the specified order, first by root, then by template name. For example:
myzipfile = TemplateZipFile(response, mode='w', compression=ZIP_DEFLATED, template_root=['override/', 'default/'])
myzipfile.write_template(['two.txt', 'one.txt'], filename='myfile.txt')

# Will use the first existing template from ['override/two.txt', 'override/one.txt', 'default/two.txt', 'default/one.txt']
If none of the templates can be found, write_template will raise a TemplateDoesNotExist error.
You can specify a file as optional with optional=True
myzipfile.write_template(['two.txt', 'one.txt'], filename='myfile.txt', optional=True)
Doing so will silently swallow the TemplateDoesNotExist exception.
