CookBook - Data Models
A "category" data model - for use in custom documents, weblog entries, etc.
An efficient parent/child relationship - Similar to the "category" data model above, but doesn't use recursive functions, neither multiple queries.
Using markup filters in models - efficiently using Markdown, Textile, etc. in models
A "Constants" class - a neat trick to enhance the choices functionality
Splitting models to multiple files - it is possible after all
Predicates - or "3-tuples" or "semantically enriched many-to-many relationships".
The Pages in this section refer to older version of Django:
CookBookMultiLevelMultiComponentDataModel - Multiple "levels" & multiple components
[wiki:CookBookCategoryDataModel ] - A "category" data model for use in custom documents, weblog entries, etc.
CookBookTreeStructure - A tree DB system that is fast for insert, select and delete. Requires small change to django source.
[wiki:CookBookLabels ] - Labels/tags for any model with a single line in the model code.
