Mako Integration
|
|
----------------
|
|
|
|
dogpile.cache includes a `Mako <http://www.makotemplates.org>`_ plugin
|
|
that replaces `Beaker <http://beaker.groovie.org>`_
|
|
as the cache backend.
|
|
Setup a Mako template lookup using the "dogpile.cache" cache implementation
|
|
and a region dictionary::
|
|
|
|
from dogpile.cache import make_region
|
|
from mako.lookup import TemplateLookup
|
|
|
|
my_regions = {
|
|
"local":make_region().configure(
|
|
"dogpile.cache.dbm",
|
|
expiration_time=360,
|
|
arguments={"filename":"file.dbm"}
|
|
),
|
|
"memcached":make_region().configure(
|
|
"dogpile.cache.pylibmc",
|
|
expiration_time=3600,
|
|
arguments={"url":["127.0.0.1"]}
|
|
)
|
|
}
|
|
|
|
mako_lookup = TemplateLookup(
|
|
directories=["/myapp/templates"],
|
|
cache_impl="dogpile.cache",
|
|
cache_args={
|
|
'regions':my_regions
|
|
}
|
|
)
|
|
|
|
To use the above configuration in a template, use the ``cached=True``
|
|
argument on any Mako tag which accepts it, in conjunction with the
|
|
name of the desired region as the ``cache_region`` argument::
|
|
|
|
<%def name="mysection()" cached="True" cache_region="memcached">
|
|
some content that's cached
|
|
</%def>
|
|
|
|
|
|
