在Yii框架中,管理用戶收藏夾通常涉及到以下幾個(gè)步驟:
class Folder extends \yii\db\ActiveRecord
{
public static function tableName()
{
return 'folder';
}
public function rules()
{
return [
[['user_id', 'item_id'], 'required'],
[['created_at'], 'safe'],
];
}
public function attributeLabels()
{
return [
'id' => 'ID',
'user_id' => 'User ID',
'item_id' => 'Item ID',
'created_at' => 'Created At',
];
}
}
class Item extends \yii\db\ActiveRecord
{
public static function tableName()
{
return 'item';
}
public function rules()
{
return [
[['id', 'name', 'description'], 'required'],
];
}
public function attributeLabels()
{
return [
'id' => 'ID',
'name' => 'Name',
'description' => 'Description',
];
}
}
class FolderController extends \yii\web\Controller
{
public function actionCreate()
{
// 創(chuàng)建收藏夾的邏輯
}
public function actionDelete($id)
{
// 取消收藏的邏輯
}
}
// views/folder/index.php
use yii\grid\GridView;
use yii\helpers\Html;
$this->title = '我的收藏夾';
echo GridView::widget([
'dataProvider' => $folderDataProvider,
'filterModel' => $folderSearchModel,
'columns' => [
// ...
],
]);
public function getItems()
{
return $this->hasMany(Item::className(), ['id' => 'item_id']);
}
public function actionIndex($userId)
{
$folder = Folder::find()->where(['user_id' => $userId])->one();
$items = $folder->items;
return $this->render('index', [
'folder' => $folder,
'items' => $items,
]);
}
// views/folder/index.php
use yii\grid\GridView;
use yii\helpers\Html;
$this->title = '我的收藏夾';
echo GridView::widget([
'dataProvider' => $folderDataProvider,
'filterModel' => $folderSearchModel,
'columns' => [
// ...
],
]);
通過(guò)以上步驟,你可以在Yii框架中管理用戶收藏夾。當(dāng)然,這只是一個(gè)簡(jiǎn)單的示例,你可能需要根據(jù)實(shí)際需求進(jìn)行調(diào)整和擴(kuò)展。
