메소드	설명
__construct ( DataModel $parentModel, string $foreignModelName, string $localKey = null, string $foreignKey = null, string $pivotTable = null, string $pivotLocalKey = null, string $pivotForeignKey = null )	Public constructor. Initialises the relation.
getCountSubquery ( string $tableAlias = null ) : JDatabaseQuery	Returns the count subquery for DataModel's has() and whereHas() methods.
getNew ( )	This is not supported by the belongsTo relation
saveAll ( )	Saves all related items. For many-to-many relations there are two things we have to do: 1. Save all related items; and 2. Overwrite the pivot table data with the new associations
saveRelations ( )	Overwrite the pivot table data with the new associations
setDataFromCollection ( Collection &$data, mixed $keyMap = null ) : void	Populates the internal $this->data collection from the contents of the provided collection. This is used by DataModel to push the eager loaded data into each item's relation.
