如何在 yii2 中过滤 gridview 表？

Question

I have two gridview tables currently, one shows all the data and the other i want it to show only data where id = 2. Is it possible to filter only one table without affecting the other? I know I can filter from the search model but that will affect all tables and i want it to affect only one.

Can i have two dataprovider?

This is the code in my search model:

class JobPlanningSearch extends JobPlanning
{
    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['id', 'priority', 'employer_id', 'client_id', 'status', 'activity'], 'integer'],
            [['job_description', 'impediment', 'date', 'estimated_time', 'due_date'], 'safe'],
        ];
    }

    /**
     * @inheritdoc
     */
    public function scenarios()
    {
        // bypass scenarios() implementation in the parent class
        return Model::scenarios();
    }

    /**
     * Creates data provider instance with search query applied
     *
     * @param array $params
     *
     * @return ActiveDataProvider
     */
    public function search($params)
    {
        $query = JobPlanning::find();

        // add conditions that should always apply here

        $dataProvider = new ActiveDataProvider([
            'query' => $query,
        ]);

        $this->load($params);

        if (!$this->validate()) {
            // uncomment the following line if you do not want to return any records when validation fails
            // $query->where('0=1');
            return $dataProvider;
        }

        // grid filtering conditions
        $query->andFilterWhere([
            'id' => $this->id,
            'priority' => $this->priority,
            'client_id' => $this->client_id,
            'employer_id' => $this->employer_id,
            'estimated_time' => $this->estimated_time,
            'status' => $this->status,
            'activity' => $this->activity,
            //'actual' => $this->actual,
            //'actual' => 1,
        ]);

        $query->andFilterWhere(['like', 'job_description', $this->job_description]);
        $query->andFilterWhere(['like', 'activity', $this->activity]);

        return $dataProvider;
    }

Answer 1

You need two dataproviders, like this:

$searchModelOne = new JobPlanningSearch();        
$dataProviderOne = $searchModelOne->search(Yii::$app->request->queryParams);
$dataProviderOne->pagination->pageParam = 'dp-one-page'; //set page param for first dataprovider
$searchModelTwo = new JobPlanningSearch();   
searchModelTwo->id = 2;     // set id = 2 in second dataprovider
$dataProviderTwo = $searchModelTwo->search(Yii::$app->request->queryParams);
$dataProviderTwo->pagination->pageParam = 'dp-two-page'; //set page param for second dataprovider

Answer 2

You will have to manipulate the DataProvider in the controller.

$searchModel = new JobPlanningSearch();        
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$dataProvider->query->andWhere(['=','id',2]);

2. remove it from the search function in JobPlanningSearch.

   $query->andFilterWhere([

    /* 'id' => $this->id, */ // you must remove it from here 'priority' => $this->priority, 'client_id' => $this->client_id, 'employer_id' => $this->employer_id, 'estimated_time' => $this->estimated_time, ...

   ]);

In this case, the ID will always be 2.

But if you want to have a default value (the first time) and allow the user to change it, you should skip step 2 . And add a condition in the controller:

...
if(count(Yii::$app->request->queryParams) == 0){
    $dataProvider->query->andWhere(['=','id',2]);
}

This is just an example, you should check that the ID field has not been sent in the queryparams.

You need to use two searchModels, one for each GridView and of course two data providers.

Also you need to change the formName attribute of one of the searchModels to avoid filtering to affects both grids.

And the in the controller, when passing parameters to the search() method of the modified searchModel, pass the params in the new name you assigned to formName in this searchModel.
