Evaluate the best option for hierarchical modeling

[eronlloyd]

Description

MPTT or CTE? I'm not yet sure this is going to be an issue, but better to design it properly up front. Based on my previous notes, this might be the solution.

Requirements

• Efficiently represent hierarchies in the database

Dependencies

• django-tree-queries

Tasks

• Write code
• Write documentation

I decided to go with django-tree-queries, and the implementation went smooth. The parent field was simply replaced by the one provided by the core.CRMTreeBase abstract model, which will be used for any model needed hierarchies of itself.
