我正在尝试为用yii2编写的新小型CMS实现带标签的文章。
这就是我尝试过的https://forum.yiiframework.com/t/how-to-create-tags-for-posts-in-yii2/123890
一切正常，标记机制正在从标记表中获取数据，但未将数据保存到表tag_assign中。
这是我的表格。
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
//Using for Wysiwig editor
use dosamigos\ckeditor\CKEditor;
//Using for Tagging
use dosamigos\selectize\SelectizeTextInput;
/* @var $this yii\web\View */
/* @var $model common\models\Articles */
/* @var $form yii\widgets\ActiveForm */
?>
<div class="articles-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'title')->textInput(['maxlength' => true]) ?>
<?= $form->field($model, 'content')->widget(CKEditor::className(), [
'options' => ['height' => 800],
'preset' => 'basic',
'clientOptions' => ['height' => 400]
]) ?>
<?= $form->field($model, 'tags')->widget(SelectizeTextInput::className(), [
// calls an action that returns a JSON object with matched
// tags
'loadUrl' => ['tag/list'],
'options' => ['class' => 'form-control'],
'clientOptions' => [
'plugins' => ['remove_button'],
'valueField' => 'name',
'labelField' => 'name',
'searchField' => ['name'],
'create' => true,
],
])->hint('Use commas to separate tags') ?>
<?= $form->field($model, 'date')->textInput() ?>
<div class="form-group">
<?= Html::submitButton('Save', ['class' => 'btn btn-success']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
这是我的标签模型
<?php
namespace common\models;
use Yii;
use dosamigos\taggable\Taggable;
/**
* This is the model class for table "tags".
*
* @property int $id
* @property string $frequency
* @property string $name
*/
class Tag extends \yii\db\ActiveRecord
{
/**
* {@inheritdoc}
*/
public static function tableName()
{
return 'tags';
}
/**
* {@inheritdoc}
*/
public function rules()
{
return [
[['frequency', 'name'], 'required'],
[['frequency'], 'string', 'max' => 500],
[['name'], 'string', 'max' => 250],
];
}
/**
* {@inheritdoc}
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'frequency' => 'Frequency',
'name' => 'Name',
];
}
//For Tagging
public function behaviors() {
return [
[
'class' => Taggable::className(),
],
];
}
public function findAllByName($name)
{
return Tag::find()->where('name LIKE :query')
->addParams([':query'=>"%$name%"])
->all();
}
}
标签控制器。
<?php
namespace backend\controllers;
use Yii;
use common\models\Tag;
use common\models\searchTag;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
use yii\web\Response;
/**
* TagController implements the CRUD actions for Tag model.
*/
class TagController extends Controller
{
/**
* {@inheritdoc}
*/
public function behaviors()
{
return [
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'delete' => ['POST'],
],
],
];
}
/**
* Lists all Tag models.
* @return mixed
*/
public function actionIndex()
{
$searchModel = new searchTag();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
/**
* Displays a single Tag model.
* @param integer $id
* @return mixed
* @throws NotFoundHttpException if the model cannot be found
*/
public function actionView($id)
{
return $this->render('view', [
'model' => $this->findModel($id),
]);
}
/**
* Creates a new Tag model.
* If creation is successful, the browser will be redirected to the 'view' page.
* @return mixed
*/
public function actionCreate()
{
$model = new Tag();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
}
return $this->render('create', [
'model' => $model,
]);
}
public function actionList($query)
{
$models = Tag::findAllByName($query);
$items = [];
foreach ($models as $model) {
$items[] = ['name' => $model->name];
}
// We know we can use ContentNegotiator filter
// this way is easier to show you here :)
Yii::$app->response->format = Response::FORMAT_JSON;
return $items;
}
/**
* Updates an existing Tag model.
* If update is successful, the browser will be redirected to the 'view' page.
* @param integer $id
* @return mixed
* @throws NotFoundHttpException if the model cannot be found
*/
public function actionUpdate($id)
{
$model = $this->findModel($id);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
}
return $this->render('update', [
'model' => $model,
]);
}
/**
* Deletes an existing Tag model.
* If deletion is successful, the browser will be redirected to the 'index' page.
* @param integer $id
* @return mixed
* @throws NotFoundHttpException if the model cannot be found
*/
public function actionDelete($id)
{
$this->findModel($id)->delete();
return $this->redirect(['index']);
}
/**
* Finds the Tag model based on its primary key value.
* If the model is not found, a 404 HTTP exception will be thrown.
* @param integer $id
* @return Tag the loaded model
* @throws NotFoundHttpException if the model cannot be found
*/
protected function findModel($id)
{
if (($model = Tag::findOne($id)) !== null) {
return $model;
}
throw new NotFoundHttpException('The requested page does not exist.');
}
}
还有文章
<?php
namespace common\models;
use Yii;
//For Taggable
use dosamigos\taggable\Taggable;
/**
* This is the model class for table "articles".
*
* @property int $id
* @property string $title
* @property string $content
* @property string $tags
* @property string $date
*/
class Articles extends \yii\db\ActiveRecord
{
//For taggable
public function behaviors() {
return [
[
'class' => Taggable::className(),
],
];
}
/**
* {@inheritdoc}
*/
public static function tableName()
{
return 'articles';
}
/**
* {@inheritdoc}
*/
public function rules()
{
return [
[['title', 'content', 'tags', 'date'], 'required'],
[['content'], 'string'],
[['date'], 'safe'],
[['title', 'tags'], 'string', 'max' => 250],
];
}
/**
* {@inheritdoc}
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'title' => 'Title',
'content' => 'Content',
'tags' => 'Tags',
'date' => 'Date',
];
}
public function getTags()
{
return $this->hasMany(Tag::className(), ['id' => 'tag_id'])->viaTable('tag_assign', ['article_id' => 'id']);
}
}
我缺少什么？至少我该如何解决问题？
