from paste.fileapp import FileApp
from pylons.controllers.util import forward
class MyController(BaseController):
def my_action(self):
path = "/mypdfs/a.pdf"
app = FileApp(path)
return forward(app)
It will guess the MIME type from the extension. You can pass keyword
args or subclass it to override the MIME type or set a caching policy.
There's also DirectoryApp in the same module if you want to serve a
hierarchy of static files. Use the 'path_info' routing variable for
this, which magically sets PATH_INFO in the WSGI environment:
map.connect("/prefix/{path_info:.*", controller="mycontroller",
action="myaction")
# Matches "/prefix/subdir/subdir2/a.pdf" => /mypdfs/subdir/subdir2/a.pdf
I think FileApp raises an exception if an intermediate directory
doesn't exist, which causes a 500 error rather than the desired 404.
So I capture that case and abort:
if not os.path.exists(path):
abort(404)
app = FileApp(path)
return forward(app)
