| 7 | == Purpose == |
| 8 | |
| 9 | The S3Model class defines the framework for data models in Eden. It extends the web2py concept by: |
| 10 | |
| 11 | - implicit and lazy model loading |
| 12 | - an extensible, per-table configuration pattern |
| 13 | - a meta-model for projected entities (the so-called "resource component model") |
| 14 | - a meta-model for multi-table keys (the so-called "super-entity model") |
| 15 | |
| 16 | Data models can be implemented as subclasses of S3Model, and then loaded on demand - with automatic resolution of cross-model dependencies. This saves processing time as it will always only load those models which are actually needed to process the request. |
