The main place I use [(url, label)] pairs is in breadcrumbs, which I
set in the controller:
c.crumbs = [("url", "label")]
You can certainly pickle to a BLOB column in a SQL database, the
(non-Pylons) session2 package does this for session handling. I think
SQLAlchemy might have a Pickle column type that does this for you.
But if you're talking about URL/label pairs, it might make more sense
to store them in a two-column table rather than as pickles. (With a
third or fourth column saying who these links belong to, and on what
page.)
But what kind of application needs internal links pickled? The only
use I can think of is some kind of history feature ("Where have I
been?") Otherwise, for ordinary site navigation, wouldn't it be
better to recreate the links each time using url_for and whatever
arguments are necessary -- which you would already have available?
