yii场景使用

································场景1································ 控制器：
$model->scenario=’update’;//指定场景
$model -> save();

模型中：
public function rules() {
return [
[‘name’,’required’,’message’=>’用户名不能为空’],
[‘age’,’required’,’message’=>’年龄不能为空’,’on’=>’create’],
[‘pwd’,’required’,’message’=>’密码不能为空’,’on’=>’update’]
];
}

结果：
验证name和pwd

································场景2································ 控制器：
$model->scenario=’update’;
$model -> save();

模型中：
public function rules(){
return [
[‘name’,’required’,’message’=>’用户名不能为空’],
[‘age’,’required’,’message’=>’年龄不能为空’,’on’=>’create’],
[‘pwd’,’required’,’message’=>’密码不能为空’,’on’=>’update’],
[‘level’,’required’,’message’=>’等级不能为空’,’on’=>’update’],
];
}
public function scenarios(){
return [
‘update’=>[‘pwd’],
]
}

结果：
验证pwd

································场景3································ 控制器：
$model -> save();

模型中：
public function rules(){
return [
[‘name’,’required’,’message’=>’用户名不能为空’],
[‘age’,’required’,’message’=>’年龄不能为空’,’on’=>’create’],
];
}

public function scenarios(){
return [
‘update’=>[‘pwd’],
];
}

结果：
报错，缺少场景

[‘age’,’required’,’message’=>’年龄不能为空’,’on’=>’create’],
];
}
public function scenarios(){
return [
‘update’=>[‘pwd’],
‘default’=>[‘name’]
];
}

结果：
验证name
