i have table named books and want to display "related books" in books view.
books table
`book_id`
`isbn`
`book_name`
`author_name`
`Date`
`number`
`language`
`Translator`
`abstract`
`picture`
`created_at`
controller code
public function actionView($id)
{
$model=$this->findModel($id);
$dataProvider=$this->related($model);
return $this->render('view', [
'model' => $model,
'dataProvider' => $dataProvider,
]);
}
protected function related($model)
{
$query = Books::find();
$query->select('book_id,picture, book_name,author_name,(( author_name LIKE \'%'.$model->author_name.'%\')+( book_name LIKE \'%'.$model->book_name.'%\')) as total')
->orFilterwhere(['or like','author_name' , explode(' ',$model->author_name)])
->orFilterwhere(['or like','book_name' , explode(' ',$model->book_name)])
->orderBy('total')
->limit(25);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
problom :
book_name LIKE \'%'.$model->book_name.'%\' did not accept array.
something like LIKE \'%'.explode(' ',$model->book_name).'%\'
its must be an array to work correctly.
how can i use array in select condition .
or show me some other way to get best match result on top.
tnx
First If you want Total no need to write where condition in select
$query->select('book_id,picture, book_name,author_name,(book_name+author_name) as total');
$model->author_name And $model->book_name is Array So you can do as below.
protected function related($model)
{
$query = Books::find();
$query->select('book_id,picture, book_name,author_name,(book_name+author_name) as total');
$author_names= explode(' ',$model->author_name);
foreach($author_names as $author_name)
{
$query->orFilterwhere(['like','author_name' , $author_name]);
}
$book_names=explode(' ',$model->book_name);
foreach($book_names as $book_name)
{
$query->orFilterwhere(['like','book_name' , $book_name]);
}
->orderBy('total')
->limit(25);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
}
You need to use MySQL match() against() feature (or substitute if you're using different DB).
$query = Books::find();
$query->select([
'book_id,picture', 'book_name', 'author_name',
new Expression('MATCH (author_name) AGAINST (:author_name) + MATCH (book_name) AGAINST (:book_name) AS total', [
'author_name' => $this->author_name,
'book_name' => $this->book_name,
]),
]);
if (!empty($this->author_name)) {
$query->andWhere(new Expression('MATCH (author_name) AGAINST (:author_name)', [
'author_name' => $this->author_name,
]));
}
if (!empty($this->book_name)) {
$query->andWhere(new Expression('MATCH (book_name) AGAINST (:book_name)', [
'book_name' => $this->book_name,
]));
}
$query->orderBy('total DESC')
->limit(25);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
My searchmodel
$query = (new \yii\db\Query())
->select(['monthsubmit',"DATE_FORMAT(monthsubmit, '%m-%Y') as c_date", 'modeler', 'count(sku) as count'])
->from('sku3d')
->groupBy(['monthsubmit', 'modeler'])
->orderBy(['monthsubmit'=>SORT_DESC, 'modeler'=>SORT_DESC]);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
My controller
$searchModel = new Sku3dSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
My gridview
<?php echo GridView::widget([
'dataProvider' => $dataProvider,
'filterModel'=>$searchModel,
'pjax'=>true,
'panel' => [
'type' => GridView::TYPE_PRIMARY,
'heading' => '<h3 class="panel-title"><i class="glyphicon glyphicon-user"></i>Submitted SKU by Month</h3>',
],
'columns' => [
[
'attribute'=>'monthsubmit',
'width'=>'310px',
'filter'=>ArrayHelper::map(Sku3d::find()->orderBy('monthsubmit')->asArray()->all(), 'monthsubmit', 'monthsubmit'),
'group'=>true,
],
[
'attribute'=>'modeler',
'width'=>'180px',
'group'=>true,
],
'count:text:Total Sku',
]
]);
?>
At first I didn't use querybuilder in searchmodel but in controller and everything worked fine. But I need to filter it also so i moved my querybuilder into searchmodel.
When I did this, it had error "Getting unknown property:app\models\Sku3d::count".
How can I call the 'count(sku) as count' to my gridview. And also it look like my groupBy(['monthsubmit', 'modeler']) not working also.
Please tell me where I'm wrong.
Thank you.
In your searchmodel add a publica var
class Sku3dSearch extends Sku3d
{
public $count;
/**
* #inheritdoc
*/
public function rules()
......
$query = (new \yii\db\Query())
->select(['monthsubmit',"DATE_FORMAT(monthsubmit, '%m-%Y') as c_date", 'modeler', 'count(sku) as count'])
->from('sku3d')
->groupBy(['monthsubmit', 'modeler'])
->orderBy(['monthsubmit'=>SORT_DESC, 'modeler'=>SORT_DESC]);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
}
TL;DR
I have a query that works in RAW SQL but i have had little success recreating it with query builder or active record.
I am working on a web application based off of the yii2 advanced application template. I have written a database query and implemented it with findbysql() returning the correct records but am having trouble translating this into active record.
I originally wanted to allow the user to modify (filter) the results by means of a search form(user & date), however i have since realized that implementing filters on the gridview with active records would be smoother.
I have gotten simple queries to work however am unsure of how to implement one with this many joins. Many examples used sub queries but my attempts failed to return any records at all. I figured before I attempt filters i need to transcribe this query first.
videoController.php
public function actionIndex()
{
$sql = 'SELECT videos.idvideo, videos.filelocation, events.event_type, events.event_timestamp
FROM (((ispy.videos videos
INNER JOIN ispy.cameras cameras
ON (videos.cameras_idcameras = cameras.idcameras))

AND (events.event_type IN (23, 24))
AND (events.event_timestamp BETWEEN videos.start_time
AND videos.end_time)';
$query = Videos::findBySql($sql);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
return $this->render('index', [
'dataProvider' => $dataProvider,
]);
}

Please let me know if i need to be more specific or include any additional information.

i will assume, based on the question you asked here you liked in comments that you provided the entire query
(no other fields, that you took out just to show sample code)
therefore, if you only need only the fields specified in SELECT statement, you can optimize your query quite a bit:
first off, you're joining with host_machines only to link cameras and events, but have the same key host_machines_idhost_machines on both, so that's not needed, you can directly:
INNER JOIN events events
ON (events.host_machines_idhost_machines =
cameras.host_machines_idhost_machines))
secondly, the join with ispy.staff, the only used field is idreceptionist in WHERE clause, that field exists in events as well so we can drop it completly
the final query here:
SELECT videos.idvideo, videos.filelocation, events.event_type, events.event_timestamp
FROM videos videos
INNER JOIN cameras cameras
ON videos.cameras_idcameras = cameras.idcameras
INNER JOIN events events
ON events.host_machines_idhost_machines =
cameras.host_machines_idhost_machines
WHERE (events.staff_idreceptionist = 182)
AND (events.event_type IN (23, 24))
AND (events.event_timestamp BETWEEN videos.start_time
AND videos.end_time)
should output the same records as the one in your question, without any identitcal rows
some video duplicates will still exists due to one to many relation between cameras and events
now to the yii side of things,
you have to define some relations on the Videos model
// this is pretty straight forward, `videos`.`cameras_idcameras` links to a
// single camera (one-to-one)
public function getCamera(){
return $this->hasOne(Camera::className(), ['idcameras' => 'cameras_idcameras']);
}
// link the events table using `cameras` as a pivot table (one-to-many)
public function getEvents(){
return $this->hasMany(Event::className(), [
// host machine of event => host machine of camera (from via call)
'host_machines_idhost_machines' => 'host_machines_idhost_machines'
])->via('camera');
}
the VideoController and the search function itself
public function actionIndex() {
// this will be the query used to create the ActiveDataProvider
$query =Video::find()
->joinWith(['camera', 'events'], true, 'INNER JOIN')
->where(['event_type' => [23, 24], 'staff_idreceptionist' => 182])
->andWhere('event_timestamp BETWEEN videos.start_time AND videos.end_time');
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
return $this->render('index', [
'dataProvider' => $dataProvider,
]);
}
yii will treat each video as a single record (based on pk), that means that all video duplicates are
removed. you will have single videos, each with multiple events so you wont be able to use 'event_type'
and 'event_timestamp' in the view but you can declare some getters inside Video model to show that info:
public function getEventTypes(){
return implode(', ', ArrayHelper::getColumn($this->events, 'event_type'));
}
public function getEventTimestamps(){
return implode(', ', ArrayHelper::getColumn($this->events, 'event_timestamp'));
}
and the view use:
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'idvideo',
'eventTypes',
'eventTimestamps',
'filelocation',
//['class' => 'yii\grid\ActionColumn'],
],
]); ?>
edit:
if you want to keep the video duplicates, declare the two columns from events inside Video model
public $event_type, $event_timestamp;
keep the original GridView setup, and add a select and indexBy this to the query inside VideoController:
$q = Video::find()
// spcify fields
->addSelect(['videos.idvideo', 'videos.filelocation', 'events.event_type', 'events.event_timestamp'])
->joinWith(['camera', 'events'], true, 'INNER JOIN')
->where(['event_type' => [23, 24], 'staff_idreceptionist' => 182])
->andWhere('event_timestamp BETWEEN videos.start_time AND videos.end_time')
// force yii to treat each row as distinct
->indexBy(function () {
static $count;
return ($count++);
});
update
a direct staff relation to Video is currently somewhat problematic since that is more than one table away from it.
there's an issue about it here
however, you add the staff table by linking it to the Event model,
public function getStaff() {
return $this->hasOne(Staff::className(), ['idreceptionist' => 'staff_idreceptionist']);
}
that will allow you to query like this:
->joinWith(['camera', 'events', 'events.staff'], true, 'INNER JOIN')
Filtering will require some small updates on the controller, view and a SarchModel
here's a minimal implementation:
class VideoSearch extends Video
{
public $eventType;
public $eventTimestamp;
public $username;
public function rules() {
return array_merge(parent::rules(), [
[['eventType', 'eventTimestamp', 'username'], 'safe']
]);
}
public function search($params) {
// add/adjust only conditions that ALWAYS apply here:
$q = parent::find()
->joinWith(['camera', 'events', 'events.staff'], true, 'INNER JOIN')
->where([
'event_type' => [23, 24],
// 'staff_idreceptionist' => 182
// im guessing this would be the username we want to filter by
])
->andWhere('event_timestamp BETWEEN videos.start_time AND videos.end_time');
$dataProvider = new ActiveDataProvider(['query' => $q]);
if (!$this->validate())
return $dataProvider;
$this->load($params);
$q->andFilterWhere([
'idvideo' => $this->idvideo,
'events.event_type' => $this->eventType,
'events.event_timestamp' => $this->eventTimestamp,
'staff.username' => $this->username,
]);
return $dataProvider;
}
}
controller:
public function actionIndex() {
$searchModel = new VideoSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('test', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
and the view
use yii\grid\GridView;
use yii\helpers\ArrayHelper;
echo GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'idvideo',
'filelocation',
[
'attribute' => 'eventType', // from VideoSearch::$eventType (this is the one you filter by)
'value' => 'eventTypes' // from Video::getEventTypes() that i suggested yesterday
// in hindsight, this could have been named better, like Video::formatEventTypes or smth
],
[
'attribute' => 'eventTimestamp',
'value' => 'eventTimestamps'
],
[
'attribute' => 'username',
'value' => function($video){
return implode(', ', ArrayHelper::map($video->events, 'idevent', 'staff.username'));
}
],
//['class' => 'yii\grid\ActionColumn'],
],
]);
My recommendation would be to have 2 queries. The first one to get the ids of the videos that fit your search, the second query theone that uses those ids and feeds your $dataProvider.
use yii\helpers\ArrayHelper;
...
public function actionIndex()
{
// This is basically the same query you had before
$searchResults = Videos::find()
// change 'id' for the name of your primary key
->select('id')
// we don't really need ActiveRecord instances, better use array
->asArray()
->innerJoin('cameras', 'videos.cameras_idcameras = cameras.idcameras')
->innerJoin('host_machines', 'cameras.host_machines_idhost_machines = host_machines.idhost_machines')
->innerJoin('events', 'events.host_machines_idhost_machines = host_machines.idhost_machines')
->innerJoin('staff', 'events.staff_idreceptionist = staff.idreceptionist')
->where('staff.idreceptionist = 182')
->andWhere(['events.event_type' => [23,24]])
->andwhere(['between', 'events.event_timestamp', 'videos.start_time', 'videos.end_time'])
// query the results
->all();
// this will be the query used to create the ActiveDataProvider
$query = Videos::find()
// and we use the results of the previous query to filter this one
->where(['id' => ArrayHelper::getColumn($searchResults, 'id')]);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
return $this->render('index', [
'dataProvider' => $dataProvider,
]);
}
I've used the Gii AJAX Crud generator, and I'm being driven up a wall by my own stupidity. I am using Yii 2 and want to search with many to many, on a table that has that relation with ITSELF in a junction table, with the Grid View.
table tag (id, name).
table tag_child (parent_id, child_id)
Class Tag
...
public function getParents()
{
return $this->hasMany(self::className(), ['id' => 'child_id'])
->viaTable('tag_child', ['parent_id' => 'id']);
}
public function getChildren()
{
return $this->hasMany(self::className(), ['id' => 'parent_id'])
->viaTable('tag_child', ['child_id' => 'id']);
}
And in my grid-view /columns:
[
'class' => '\kartik\grid\DataColumn',
'attribute'=>'name',
],
[
'class' => '\kartik\grid\DataColumn',
'label' => 'Tag Type',
'value' => function($tag) {
return $tag->displayTagTypes();
},
'attribute' => 'tagTypes'
],
TagQuery.php
...
public $tagTypes;
public function search($params)
{
$query = Tag::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$this->load($params);
if (!$this->validate()) {
// $query->where('0=1');
return $dataProvider;
}
$query->joinWith('parents p');
$query->andFilterWhere(['id' => $this->id]);
$query->andFilterWhere(['like', 'tag.name', $this->name]);
return $dataProvider;
}
I'm able to display the results in my index table with that value function, but my Tag filter isn't able to search by tagTypes. How do I populate that?
As an example, when it's not many to many, I can use set my attribute to 'joinedTableName.value' and it works as soon as I add a $query->orFilterWhere('like', 'parent.name', $this->id) or whatever. But I'm at a loss now...
Declare $searchModel = new TagQuery() in your controller, then pass the $searchModel to the view and include it in the GridView options as 'filterModel' => $searchModel.
Either that, or you can do really custom filters using specific filterTypes and filter logic for each column.
You declare public tagType in the query model, but you don't do anything with it. $query->andFilterWhere(['like', 'tag.name', $this->tagType]);
while i am fetching this records then getting this error how to solve it ?
public function actionIndex()
{
$query = Site::model();
$pagination = new CPagination([
'defaultPageSize' => 5,
'totalCount' => $query->count(),
]);
$countries = $query->orderBy('name')
->offset($pagination->offset)
->limit($pagination->limit)
->all();
return $this->render('view', [
'countries' => $countries,
'pagination' => $pagination,
]);
}
you should distinguish between yii1 and yii2.from your codes,you used yii1 and yii2 together.
