-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 * Package name : python-django-tree-queries Version : 0.15 Upstream Contact: Matthias Kestenholz <m...@feinheit.ch> * URL : https://github.com/feincms/django-tree-queries * License : BSD-3-clause Programming Lang: Python Description : Adjacency-list trees for Django Query Django model trees using adjacency lists and recursive common table expressions. Supports PostgreSQL, sqlite3 and MariaDB and MySQL. . Features and limitations: * Supports only integer and UUID primary keys (for now). * Allows specifying ordering among siblings. * Uses the correct definition of depth, where root nodes have a depth of zero. * The parent foreign key must be named "parent" at the moment. * The fields added by the common table expression always are tree_depth, tree_path and tree_ordering. The names cannot be changed. tree_depth is an integer, tree_path an array of primary keys and tree_ordering an array of values used for ordering nodes within their siblings. * Besides adding the fields mentioned above the package only adds queryset methods for ordering siblings and filtering ancestors and descendants. * Little code, and relatively simple when compared to other tree management solutions for Django. No redundant values so the only way to end up with corrupt data is by introducing a loop in the tree structure (making it a graph). The TreeNode abstract model class has some protection against this. * Supports only trees with max. 50 levels on MySQL/MariaDB, since those databases do not support arrays and require a maximum length for the tree_path and tree_ordering upfront. This is a dependency for django-content-editor and I will maintain it as part of the DPT. -----BEGIN PGP SIGNATURE----- iQFPBAEBCgA5FiEEqVSlRXW87UkkCnJc/9PIi5l90WoFAmVRCg0bHGZsYWRpc2No ZXJtaWNoYWVsQGZsYWRpLmF0AAoJEP/TyIuZfdFqExoH/3X/gCg2xKOY6q8rJ3aB +EA+MWwIZFgFmgYPTmO3HOF8u/2HCT8rYZ9WNGgJjjVyeC2ozezNFJaLHN3qEljj rdCJ7wG6/qgSnH5W+olk99r9ZXFeifMa2D7zDE6cd0LMSYX1WUlMIy+Ywpi10Jmz kJ+iBzGdH97kGIP5o5T4cR2+UfHIgv1Xf9qyTjPBHTQ94672Re1jYOms5T1QuDTg Z+Tfaz8gQriCVaZJCxK2nytMzXk8slFMiS5qKWi1iTii2PORY7xhosy9iZvdqGqv VwRgE8wPzDVgjB5xP83vuIUbTRzEnZ4bbUlOYZWEXq/4MdH7iRQgh30ZNlMlsg9K ZwY= =l/cw -----END PGP SIGNATURE-----
