Overview

Interaction between a user and an organization can be done via an Assembly. It’s a unit of action from the Organization point of view that groups several components (proposals, debates…) that can be enabled or disabled.

An assembly can have children. This is implemented using a PostgreSQL extension: LTREE The LTREE extension allows us to save, query on and manipulate trees (hierarchical data structures). It uses the path enumeration algorithm, which calls for each node in the tree to record the path from the root you would have to follow to reach that node.

We use the ‘parents_path` column to save the path and query the tree. Example:

A (root assembly) parent = null, parents_path = A B (root assembly) parent = null, parents_path = B |- C (child assembly of B, descendant of B) parent = B, parents_path = B.C

|- D (child assembly of C, descendant of B,C) parent = C, parents_path = B.C.D
|- E (child assembly of C, descendant of B,C) parent = C, parents_path = B.C.E
   |- F (child assembly of E, descendant of B,C,E) parent = E, parents_path = B.C.E.F
