Models and relations

The Model

SimpleAR uses, for now, a Domain Model to manage objects. The Model class is the heart of this approach.

Table

User uses Model to give information about its table (columns, table name...) but these are parsed at class loading and then stored in a Table object.

Here is the process:

  1. Autoloader loads class file and triggers Model::wakeup() class method;
  2. Model parses data provided by user ($_columns, $_tableName, $_primaryKey...) or, if not given, tries to guess stuff out of its class name. If columns are not given, SimpleAR will perform a query to the DB.
  3. Create a Table object with these informations and store it.

Table objects are stored in a Model::$_tables, a static array that associate model class name to Table objects.

Then, every needed information is accessed through the Table.

Table object can be accessed with Model::table() method.
