Changes Related with Model Scenarios
• Removed CModel::safeAttributes(). Safe attributes are now defined to be those that
are being validated by some rules as defined in CModel::rules() for the particular
scenario.
• Changed CModel::validate(), CModel::beforeValidate() and CModel::afterValidate().
CModel::setAttributes(), CModel::getSafeAttributeNames() The 'scenario' parameter
is removed. You should get and set the model scenario via CModel::scenario.
• Changed CModel::getValidators() and removed CModel::getValidatorsForAttribute().
CModel::getValidators() now only returns validators applicable to the scenario as
specified by the model's scenario property.
• Changed CModel::isAttributeRequired() and CModel::getValidatorsForAttribute(). The
scenario parameter is removed. The model's scenario property will be used, instead.
• Removed CHtml::scenario. CHtml will use the model's scenario property instead.
Changes Related with Eager Loading for Relational Active Record
• By default, a single JOIN statement will be generated and executed for all relations
involved in the eager loading. If the primary table has its LIMIT or OFFSET query
option set, it will be queried alone first, followed by another SQL statement that brings
back all its related objects. Previously in version 1.0.x, the default behavior is that
there will be N+1 SQL statements if an eager loading involves N HAS_MANY or
MANY_MANY relations.
Changes Related with Table Alias in Relational Active Record
• The default alias for a relational table is now the same as the corresponding relation
name. Previously in version 1.0.x, by default Yii would automatically generate a table
