공개 프로퍼티들

프로퍼티	타입	설명
$_default_class_addExpression	string	The class used by addField() method.
$_default_class_addField	string	The class used by addField() method.
$_default_class_hasMany	string	The class used by hasMany() method.
$_default_class_hasOne	string	The class used by hasOne() method.
$_default_class_join	string	The class used by join() method.
$_dirty_after_reload		Save record.
$conditions	array	Conditions list several conditions that must be met by all the records in the associated DataSet. Conditions are stored as elements of array of 1 to 3. Use addCondition() to add new conditions.
$data	array	Avoid accessing $data directly, use set() / get() instead.
$dirty	array	If the value you set equal to the original value, then the key in this array will be removed. The $dirty data will be reset after you save() the data but it is still available to all before/after save handlers.
$id	mixed	Contains ID of the current record. If the value is null then the record is considered to be new.
$id_field	string	While in most cases your id field will be called 'id', sometimes you would want to use a different one or maybe don't create field at all.
$limit	array	Array of limit set.
$load_normalization	boolean	When set to true, loading model from database will also perform value normalization. Use this if you think that persistence may contain badly formatted data that may impact your business logic.
$only_fields	false | array	When you have used onlyFields() before loading the data for this model, then only that set of fields will be available. Attempt to access any other field will result in exception. This is to ensure that you do not accidentally access field that you have explicitly excluded. The default behavior is to return NULL and allow you to set new fields even if addField() was not used to set the field.
$order	array	Array of set order by.
$persistence	Persistence	Persistence driver inherited from atk4\data\Persistence.
$persistence_data	array	Persistence store some custom information in here that may be useful for them. The key is the name of persistence driver.
$reload_after_save	boolean | null	This is to ensure that any SQL-based calculation are executed and updated correctly after you have performed any modifications to the fields. You can set this property to "true" or "false" if you want to explicitly enable or disable reloading.
$strict_types	boolean	When set to true, all the field types will be enforced and normalized when setting.
$table	string | array	You can define this field as associative array where "key" is used as the name of persistence driver. Here is example for mysql and default: $table = ['user', 'mysql'=>'tbl_user'];
$title_field	string	$model->importRows(['Bananas','Oranges']); // 2 records imported

$strict_field_check	boolean	In some situations you want to set field value and then declare it later, then set $strict_field_check = false, but it's not recommended.

공개 메소드들

메소드	설명
__clone ( )
__construct ( Persistence | array $persistence = null, array $defaults = [] )	Creation of the new model can be done in two ways:.
__debugInfo ( ) : array	Returns array with useful debug info for var_dump.
_init ( )
_unset ( string | array $name )	Remove current field value and use default.
action ( string $mode, array $args = [] ) : atk4\dsql\Query	Execute action.
addCondition ( mixed $field, mixed $operator = null, mixed $value = null )	Narrow down data-set of the current model by applying additional condition. There is no way to remove condition once added, so if you need - clone model.
addExpression ( string $name, array $defaults ) : Field_Callback	Add expression field.
addField ( string $name, array $defaults = [] ) : Field	Adds new field into model.
addFields ( array $fields = [], array $defaults = [] )	Adds multiple fields into model.
addRef ( string $link, array $callback ) : object	Add generic relation. Provide your own call-back that will return the model.
allFields ( )	Sets that we should select all available fields.
asModel ( string $class, array $options = [] ) : Model	This will cast Model into another class without loosing state of your active record.
atomic ( callable $f ) : mixed	Atomic executes operations within one begin/end transaction, so if the code inside callback will fail, then all of the transaction will be also rolled back.
delete ( mixed $id = null )	Delete record with a specified id. If no ID is specified then current record is deleted.
duplicate ( mixed | null $new_id = null )	Keeps the model data, but wipes out the ID so when you save it next time, it ends up as a new record in the database.
each ( string | callable $method )	Executes specified method or callback for each record in DataSet.
export ( array | null $fields = null ) : array	Export DataSet as array of hashes.
get ( mixed $field = null ) : mixed	Returns field value.
getIterator ( ) : mixed	Returns iterator (yield values).
getRef ( string $link ) : Field	Return reference field.
getRefs ( ) : array	Returns all reference fields.
hasMany ( string $link, array $defaults = [] ) : Reference_Many	Add hasMany field.
hasOne ( string $link, array $defaults = [] ) : Reference_One	Add hasOne field.
hasRef ( string $link ) : Field | boolean	Return reference field or false if reference field does not exist.
import ( $rows )	Even more faster method to add data, does not modify your current record and will not return anything.
init ( )	Extend this method to define fields of your choice.
insert ( array $row ) : mixed	Faster method to add data, that does not modify active record.
isDirty ( $fields = [] ) : boolean	Will return true if any of the specified fields are dirty.
join ( string $foreign_table, array $defaults = [] ) : Join	Creates an objects that describes relationship between multiple tables (or collections).
leftJoin ( string $foreign_table, array $defaults = [] ) : Join	Left Join support.
load ( mixed $id )	Load model.
loadAny ( )	Load any record.
loadBy ( mixed $field, mixed $value )	Load record by condition.
loaded ( ) : boolean	Is model loaded?
newInstance ( string $class = null, array $options = [] ) : Model	Create new model from the same base class as $this.
offsetExists ( string $name ) : boolean	Do field exist?
offsetGet ( string $name ) : mixed	Returns field value.
offsetSet ( string $name, mixed $val )	Set field value.
offsetUnset ( string $name )	Redo field value.
onlyFields ( array $fields = [] )	Sets which fields we will select.
rawIterator ( ) : Iterator	Returns iterator.
ref ( string $link, array $defaults = [] ) : Model	Traverse to related model.
refLink ( string $link, array $defaults = [] ) : Model	Returns model that can be used for generating sub-query actions.
refModel ( string $link, array $defaults = [] ) : Model	Return related model.
reload ( )	Reload model by taking its current ID.
save ( $data = [] )
saveAndUnload ( array $data = [] )	Store the data into database, but will never attempt to reload the data. Additionally any data will be unloaded.
saveAs ( string $class, array $options = [] ) : Model	Saves the current record by using a different model class. This is similar to:.
set ( string | array $field, mixed $value = null )	Set field value.
setDefaults ( array $defaults )	Set default properties of model.
setLimit ( integer $count, integer | null $offset = null )	Set limit of DataSet.
setOrder ( mixed $field, boolean | null $desc = null )	Set order for model records. Multiple calls.
tryLoad ( mixed $id )	Try to load record.
tryLoadAny ( )	Try to load any record.
tryLoadBy ( mixed $field, mixed $value )	Try to load record by condition.
unload ( )	Unload model.
withID ( mixed $id )	Shortcut for using addCondition(id_field, $id).
withPersistence ( Persistence $persistence, mixed $id = null, string $class = null )	Create new model from the same base class as $this. If you omit $id,then when saving a new record will be created with default ID.

_hasReference ( string $c, string $link, array $defaults = [] ) : object	Private method.
_rawInsert ( Model $m, array $row )	This is a temporary method to avoid code duplication, but insert / import should be implemented differently.
