之前在yii1里
提交数据是$model->load()$model->save()比如我要把 date类型转为int类型会在 beforesave（）里$this->date = time()转换
$model->load()
$model->save()
$this->date = time()
但是在yii2里
beforeSave(){$this->date = time()}
会先走validate的 rule方法
就是说 没有进beforeSave转换之前就先执行了， 那beforeSave还有毛用了
光阴似箭催人老，日月如移越少年。
如果楼主是单纯想要给时间字段赋值，建议在模型里添加如下代码：
phppublic function behaviors() { return [ [ 'class' => TimestampBehavior::className(), 'attributes' => [ ActiveRecord::EVENT_BEFORE_INSERT => ['created_at','updated_at'], ActiveRecord::EVENT_BEFORE_UPDATE => 'updated_at' ], ], }
php
public function behaviors() { return [ [ 'class' => TimestampBehavior::className(), 'attributes' => [ ActiveRecord::EVENT_BEFORE_INSERT => ['created_at','updated_at'], ActiveRecord::EVENT_BEFORE_UPDATE => 'updated_at' ], ], }
然后我再正面回答一下楼主问题，流程如下：
flowst=>start: $model->save(runValidation) e=>end: 整个请求结束 runValidation=>condition: runValidation？ beforeValidate=>operation: beforeValidate validate=>operation: validate(rules在这儿执行) afterValidate=>operation: afterValidate beforeSave=>operation: beforeSave save=>operation: save afterSave=>operation: afterSave st->runValidation runValidation(yes,right)->beforeValidate runValidation(no)->beforeSave beforeValidate->validate->afterValidate(left)->beforeSave beforeSave->save->afterSave->e
flow
st=>start: $model->save(runValidation) e=>end: 整个请求结束 runValidation=>condition: runValidation？ beforeValidate=>operation: beforeValidate validate=>operation: validate(rules在这儿执行) afterValidate=>operation: afterValidate beforeSave=>operation: beforeSave save=>operation: save afterSave=>operation: afterSave st->runValidation runValidation(yes,right)->beforeValidate runValidation(no)->beforeSave beforeValidate->validate->afterValidate(left)->beforeSave beforeSave->save->afterSave->e
我勒个去，为了画这个流程图，我专门去看了下markdown的流程图语法。。。一晚上时间就白费了。。。楼主，你要负责
markdown
这样写试试：
public function beforeSave($insert) { if (parent::beforeSave($insert)) { $this->date = time(); return true; } else { return false; } }
不知道题主是什么困扰，但是你如果是非得不走rules()，可以直接在save()方法指定$runValidation为false
rules()
save()
$runValidation
false
RTFM
