在 Yii 2.0 上，声明与需验证模型特性相关的验证规则，使用了[[yii\behaviors\TimestampBehavior]]，重写 [[yii\base\Model::rules()]] 方法的技巧
1、/common/models 目录中的模型类文件仅允许Gii工具所生成，为公共的模型数据层，如图1
图1
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | /** * {@inheritdoc} */public function rules(){ return [ [['group_id', 'config_column_id', 'plan_id', 'title', 'config_task_id', 'create_user_id', 'create_name', 'exec_user_id', 'exec_name', 'task_data', 'ended_at', 'created_at', 'updated_at'], 'required'], [['config_column_id', 'plan_id', 'sort_order', 'config_task_id', 'create_user_id', 'exec_user_id', 'ended_at', 'current_step_id', 'status', 'created_at', 'updated_at'], 'integer'], [['task_info', 'task_data'], 'string'], [['group_id', 'create_name', 'exec_name'], 'string', 'max' => 32], [['title'], 'string', 'max' => 64], [['place'], 'string', 'max' => 255], ];} |
2、/common/logics 目录中的模型类文件为业务逻辑相关，继承至 /common/models 数据层，为公共的模型逻辑层，验证规则为场景相关的规则与公共的模型数据层的规则，在必填项中删除 created_at, updated_at
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 | /** * @inheritdoc */public function rules(){ return [ /* 指派(创建任务) */ [ [ 'plan_id', 'title', 'config_task_id', 'exec_user_id'], 'required', 'on' => 'create' ], //create [ 'config_task_id', 'exist', 'targetClass' => '\common\logics\ConfigTask', 'targetAttribute' => 'id', 'filter' => [ 'status' => ConfigTask::CONFIG_TASK_STATUS_ENABLE ], 'on' => 'create' ], //create [ 'plan_id', 'exist', 'targetClass' => '\common\logics\Plan', 'targetAttribute' => 'id', 'filter' => [ 'status' => Plan::PLAN_STATUS_PASSED ], 'on' => 'create' ], //create [ 'create_user_id', 'exist', 'targetClass' => '\common\logics\ConfigColumnUser', 'targetAttribute' => [ 'create_user_id' => 'user_id', 'config_column_id' => 'config_column_id' ], 'filter' => [ 'status' => ConfigColumnUser::CONFIG_COLUMN_USER_STATUS_ENABLE ], 'on' => 'create' ], //create [ 'exec_user_id', 'exist', 'targetClass' => '\common\logics\ConfigColumnUser', 'targetAttribute' => [ 'exec_user_id' => 'user_id', 'config_column_id' => 'config_column_id' ], 'filter' => [ 'status' => ConfigColumnUser::CONFIG_COLUMN_USER_STATUS_ENABLE ], 'on' => 'create' ], //create [ [ 'place', 'task_info' ], 'default', 'value' => '', 'on' => 'create' ], //create /* 我的任务(获取任务列表) */ [ [ 'status' ], 'in', 'range' => [ self::PLAN_TASK_STATUS_ALL, self::PLAN_TASK_STATUS_NOT_BEGINNING, self::PLAN_TASK_STATUS_BEGINNING, self::PLAN_TASK_STATUS_DONE ], 'on' => 'index' ], //index [ [ 'config_task_id' ], 'in', 'range' => array_merge([ ConfigTask::CONFIG_TASK_STATUS_ALL ], ConfigTask::find()->select('id')->where([ 'status' => ConfigTask::CONFIG_TASK_STATUS_ENABLE ])->asArray()->column()), 'on' => 'index' ], //index [ [ 'plan_id' ], 'default', 'value' => 0, 'on' => 'index' ], //index [ [ 'status', 'config_task_id' ], 'default', 'value' => self::PLAN_TASK_STATUS_ALL, 'on' => 'index' ], //index /* 认领(认领任务) */ [ 'id', 'exist', 'targetClass' => '\common\logics\PlanTask', 'targetAttribute' => [ 'id', 'exec_user_id' ], 'filter' => [ 'status' => self::PLAN_TASK_STATUS_NOT_BEGINNING ], 'on' => 'claim' ], //claim /* 转派(转派任务) */ [ [ 'exec_user_id' ], 'required', 'on' => 'transfer' ], //transfer [ 'exec_user_id', 'exist', 'targetClass' => '\common\logics\ConfigColumnUser', 'targetAttribute' => [ 'exec_user_id' => 'user_id', 'config_column_id' => 'config_column_id' ], 'filter' => [ 'status' => ConfigColumnUser::CONFIG_COLUMN_USER_STATUS_ENABLE ], 'on' => 'transfer' ], //transfer [ 'id', 'exist', 'targetClass' => '\common\logics\PlanTask', 'filter' => [ 'status' => self::PLAN_TASK_STATUS_NOT_BEGINNING ], 'on' => 'transfer' ], //transfer [['group_id', 'config_column_id', 'plan_id', 'title', 'config_task_id', 'create_user_id', 'create_name', 'exec_user_id', 'exec_name', 'task_data', 'ended_at'], 'required'], [['config_column_id', 'plan_id', 'sort_order', 'config_task_id', 'create_user_id', 'exec_user_id', 'ended_at', 'current_step_id', 'status', 'created_at', 'updated_at'], 'integer'], [['task_info', 'task_data'], 'string'], [['group_id', 'create_name', 'exec_name'], 'string', 'max' => 32], [['title'], 'string', 'max' => 64], [['place'], 'string', 'max' => 255], ]; |
3、公共的模型逻辑层，验证规则方法调整如下，如图2
图2
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | use yii\helpers\ArrayHelper;class PlanTask extends \common\models\PlanTask{ /** * @inheritdoc */ public function rules() { $rules = [ /* 指派(创建任务) */ [ [ 'plan_id', 'title', 'config_task_id', 'exec_user_id'], 'required', 'on' => 'create' ], //create [ 'config_task_id', 'exist', 'targetClass' => '\common\logics\ConfigTask', 'targetAttribute' => 'id', 'filter' => [ 'status' => ConfigTask::CONFIG_TASK_STATUS_ENABLE ], 'on' => 'create' ], //create [ 'plan_id', 'exist', 'targetClass' => '\common\logics\Plan', 'targetAttribute' => 'id', 'filter' => [ 'status' => Plan::PLAN_STATUS_PASSED ], 'on' => 'create' ], //create [ 'create_user_id', 'exist', 'targetClass' => '\common\logics\ConfigColumnUser', 'targetAttribute' => [ 'create_user_id' => 'user_id', 'config_column_id' => 'config_column_id' ], 'filter' => [ 'status' => ConfigColumnUser::CONFIG_COLUMN_USER_STATUS_ENABLE ], 'on' => 'create' ], //create [ 'exec_user_id', 'exist', 'targetClass' => '\common\logics\ConfigColumnUser', 'targetAttribute' => [ 'exec_user_id' => 'user_id', 'config_column_id' => 'config_column_id' ], 'filter' => [ 'status' => ConfigColumnUser::CONFIG_COLUMN_USER_STATUS_ENABLE ], 'on' => 'create' ], //create [ [ 'place', 'task_info' ], 'default', 'value' => '', 'on' => 'create' ], //create /* 我的任务(获取任务列表) */ [ [ 'status' ], 'in', 'range' => [ self::PLAN_TASK_STATUS_ALL, self::PLAN_TASK_STATUS_NOT_BEGINNING, self::PLAN_TASK_STATUS_BEGINNING, self::PLAN_TASK_STATUS_DONE ], 'on' => 'index' ], //index [ [ 'config_task_id' ], 'in', 'range' => array_merge([ ConfigTask::CONFIG_TASK_STATUS_ALL ], ConfigTask::find()->select('id')->where([ 'status' => ConfigTask::CONFIG_TASK_STATUS_ENABLE ])->asArray()->column()), 'on' => 'index' ], //index [ [ 'plan_id' ], 'default', 'value' => 0, 'on' => 'index' ], //index [ [ 'status', 'config_task_id' ], 'default', 'value' => self::PLAN_TASK_STATUS_ALL, 'on' => 'index' ], //index /* 认领(认领任务) */ [ 'id', 'exist', 'targetClass' => '\common\logics\PlanTask', 'targetAttribute' => [ 'id', 'exec_user_id' ], 'filter' => [ 'status' => self::PLAN_TASK_STATUS_NOT_BEGINNING ], 'on' => 'claim' ], //claim /* 转派(转派任务) */ [ [ 'exec_user_id' ], 'required', 'on' => 'transfer' ], //transfer [ 'exec_user_id', 'exist', 'targetClass' => '\common\logics\ConfigColumnUser', 'targetAttribute' => [ 'exec_user_id' => 'user_id', 'config_column_id' => 'config_column_id' ], 'filter' => [ 'status' => ConfigColumnUser::CONFIG_COLUMN_USER_STATUS_ENABLE ], 'on' => 'transfer' ], //transfer [ 'id', 'exist', 'targetClass' => '\common\logics\PlanTask', 'filter' => [ 'status' => self::PLAN_TASK_STATUS_NOT_BEGINNING ], 'on' => 'transfer' ], //transfer ]; $parentRules = parent::rules(); return ArrayHelper::merge($rules, $parentRules); }} |
4、由于使用了 [[yii\behaviors\TimestampBehavior]]，这个行为支持在 [[yii\db\ActiveRecord|Active Record]] 存储时自动更新它的时间戳属性，因此需要在验证规则中去掉：created_at, updated_at，设置其默认值为0，如图3

5、/common/models 目录中的模型类文件仅允许Gii工具所生成，为公共的模型数据层，生成的验证规则：created_at, updated_at，已经不是必填项
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | /** * {@inheritdoc} */public function rules(){ return [ [['group_id', 'config_column_id', 'plan_id', 'title', 'config_task_id', 'create_user_id', 'create_name', 'exec_user_id', 'exec_name', 'task_data', 'ended_at'], 'required'], [['config_column_id', 'plan_id', 'sort_order', 'config_task_id', 'create_user_id', 'exec_user_id', 'ended_at', 'current_step_id', 'status', 'created_at', 'updated_at'], 'integer'], [['task_info', 'task_data'], 'string'], [['group_id', 'create_name', 'exec_name'], 'string', 'max' => 32], [['title'], 'string', 'max' => 64], [['place'], 'string', 'max' => 255], ];} |
