python-django-tree-queries-doc 0.16.1-1 (ppc64el binary) in ubuntu noble

 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.
