属性详细

attributes 属性 public array getAttributes(array $names=NULL)
public void setAttributes(array $values, boolean $safeOnly=true)

Returns all attribute values.

errors 属性 只读 public array getErrors(string $attribute=NULL)

Returns the errors for all attribute or a single attribute.

iterator 属性 只读 public CMapIterator getIterator()

Returns an iterator for traversing the attributes in the model. This method is required by the interface IteratorAggregate.

safeAttributeNames 属性 只读 public array getSafeAttributeNames()

Returns the attribute names that are safe to be massively assigned. A safe attribute is one that is associated with a validation rule in the current scenario.

scenario 属性 public string getScenario()
public void setScenario(string $value)

Returns the scenario that this model is used in.

Scenario affects how validation is performed and which attributes can be massively assigned.

A validation rule will be performed when calling validate() if its 'on' option is not set or contains the current scenario value.

And an attribute can be massively assigned if it is associated with a validation rule for the current scenario. Note that an exception is the unsafe validator which marks the associated attributes as unsafe and not allowed to be massively assigned.

validatorList 属性 只读 （可用自 v1.1.2） public CList getValidatorList()

Returns all the validators declared in the model. This method differs from getValidators in that the latter would only return the validators applicable to the current scenario. Also, since this method return a CList object, you may manipulate it by inserting or removing validators (useful in behaviors). For example, $model->validatorList->add($newValidator). The change made to the CList object will persist and reflect in the result of the next call of getValidators.

validators 属性 只读 public array getValidators(string $attribute=NULL)

Returns the validators applicable to the current scenario.

方法详细

addError() 方法

public void addError(string $attribute, string $error)
$attribute	string	attribute name
$error	string	new error message

源码： framework/base/CModel.php#379 (显示) publicfunctionaddError($attribute,$error)
{
$this->_errors[$attribute][]=$error;
}

Adds a new error to the specified attribute.

addErrors() 方法

public void addErrors(array $errors)
$errors	array	a list of errors. The array keys must be attribute names. The array values should be error messages. If an attribute has multiple errors, these errors must be given in terms of an array. You may use the result of getErrors as the value for this parameter.

源码： framework/base/CModel.php#391 (显示) publicfunctionaddErrors($errors)
{
foreach($errorsas$attribute=>$error)
{
if(is_array($error))
{
foreach($erroras$e)
$this->_errors[$attribute][]=$e;
}
else
$this->_errors[$attribute][]=$error;
}
}

Adds a list of errors.

afterConstruct() 方法

protected void afterConstruct()

源码： framework/base/CModel.php#172 (显示) protectedfunctionafterConstruct()
{
if($this->hasEventHandler('onAfterConstruct'))
$this->onAfterConstruct(newCEvent($this));
}

This method is invoked after a model instance is created by new operator. The default implementation raises the onAfterConstruct event. You may override this method to do postprocessing after model creation. Make sure you call the parent implementation so that the event is raised properly.

afterValidate() 方法

protected void afterValidate()

源码： framework/base/CModel.php#199 (显示) protectedfunctionafterValidate()
{
$this->onAfterValidate(newCEvent($this));
}

This method is invoked after validation ends. The default implementation calls onAfterValidate to raise an event. You may override this method to do postprocessing after validation. Make sure the parent implementation is invoked so that the event can be raised.

attributeLabels() 方法

public array attributeLabels()
{return}	array	attribute labels (name=>label)

源码： framework/base/CModel.php#127 (显示) publicfunctionattributeLabels()
{
returnarray();
}

Returns the attribute labels. Attribute labels are mainly used in error messages of validation. By default an attribute label is generated using generateAttributeLabel. This method allows you to explicitly specify attribute labels.

Note, in order to inherit labels defined in the parent class, a child class needs to merge the parent labels with child labels using functions like array_merge().

参见

• generateAttributeLabel

attributeNames() 方法

abstract public array attributeNames()
{return}	array	模型属性名称的列表。

源码： framework/base/CModel.php#40 (显示) abstractpublicfunctionattributeNames();

源码： framework/base/CModel.php#186 (显示) protectedfunctionbeforeValidate()
{
$event=newCModelEvent($this);
$this->onBeforeValidate($event);
return$event->isValid;
}

This method is invoked before validation starts. The default implementation calls onBeforeValidate to raise an event. You may override this method to do preliminary checks before validation. Make sure the parent implementation is invoked so that the event can be raised.

behaviors() 方法

public array behaviors()
{return}	array	the behavior configurations (behavior name=>behavior configuration)

源码： framework/base/CModel.php#110 (显示) publicfunctionbehaviors()
{
returnarray();

Returns a list of behaviors that this model should behave as. The return value should be an array of behavior configurations indexed by behavior names. Each behavior configuration can be either a string specifying the behavior class or an array of the following structure:

'behaviorName'=>array(  'class'=>'path.to.BehaviorClass',  'property1'=>'value1',  'property2'=>'value2',
)

Note, the behavior classes must implement IBehavior or extend from CBehavior. Behaviors declared in this method will be attached to the model when it is instantiated.

For more details about behaviors, see CComponent.

clearErrors() 方法

public void clearErrors(string $attribute=NULL)
$attribute	string	attribute name. Use null to remove errors for all attribute.

源码： framework/base/CModel.php#409 (显示) publicfunctionclearErrors($attribute=null)

{
returnucwords(trim(strtolower(str_replace(array('-','_','.'),'',preg_replace('/(?<![A-Z])[A-Z]/','',$name)))));
}

Generates a user friendly attribute label. This is done by replacing underscores or dashes with blanks and changing the first letter of each word to upper case. For example, 'department_name' or 'DepartmentName' becomes 'Department Name'.

getAttributeLabel() 方法

public string getAttributeLabel(string $attribute)
$attribute	string	the attribute name

This method should be overridden to declare validation rules. Each rule is an array with the following structure:

array('attribute list', 'validator name', 'on'=>'scenario name', ...validation parameters...)

where

• attribute list: specifies the attributes (separated by commas) to be validated;
• validator name: specifies the validator to be used. It can be the name of a model classmethod, the name of a built-in validator, or a validator class (or its path alias).A validation method must have the following signature:

  // $params refers to validation parameters given in the rule
  function validatorName($attribute,$params)
  

  A built-in validator refers to one of the validators declared in CValidator::builtInValidators.And a validator class is a class extending CValidator.
• on: this specifies the scenarios when the validation rule should be performed.Separate different scenarios with commas. If this option is not set, the rulewill be applied in any scenario. Please see scenario for more details about this option.
• additional parameters are used to initialize the corresponding validator properties.Please refer to individal validator class API for possible properties.

The following are some examples:

array(  array('username', 'required'),  array('username', 'length', 'min'=>3, 'max'=>12),  array('password', 'compare', 'compareAttribute'=>'password2', 'on'=>'register'),  array('password', 'authenticate', 'on'=>'login'),
);

Note, in order to inherit rules defined in the parent class, a child class needs to merge the parent rules with child rules using functions like array_merge().
