22 #.apidoc title: Object Relational Mapping
23 #.apidoc module-mods: member-order: bysource
26 Object relational mapping to database (postgresql) module
27 * Hierarchical structure
28 * Constraints consistency, validations
29 * Object meta Data depends on its status
30 * Optimised processing by complex query (multiple actions at once)
31 * Default fields value
32 * Permissions optimisation
33 * Persistant object: DB postgresql
35 * Multi-level caching system
36 * 2 different inheritancies
38 - classicals (varchar, integer, boolean, ...)
39 - relations (one2many, many2one, many2many)

2208 **Expressing a search domain (args)**
2210 Each tuple in the search domain needs to have 3 elements, in the form: **('field_name', 'operator', value)**, where:
2212 * **field_name** must be a valid name of field of the object model, possibly following many-to-one relationships using dot-notation, e.g 'street' or 'partner_id.country' are valid values.
2213 * **operator** must be a string with a valid comparison operator from this list: ``=, !=, >, >=, <, <=, like, ilike, in, not in, child_of, parent_left, parent_right``
2214 The semantics of most of these operators are obvious.
2215 The ``child_of`` operator will look for records who are children or grand-children of a given record,
2216 according to the semantics of this model (i.e following the relationship field named by
2217 ``self._parent_name``, by default ``parent_id``.
2218 * **value** must be a valid value to compare with the values of **field_name**, depending on its type.
2220 Domain criteria can be combined using 3 logical operators than can be added between tuples: '**&**' (logical AND, default), '**|**' (logical OR), '**!**' (logical NOT).
2221 These are **prefix** operators and the arity of the '**&**' and '**|**' operator is 2, while the arity of the '**!**' is just 1.
2222 Be very careful about this when you combine them the first time.
