Yii Framework 2.0 GridView and data from the join table - php

Question

I have two database tables 'user' and 'role'. I used Yii framework 2.0 Gii to create CRUD with User model and UserSearch model. By default, Gii uses GridView::widget for the index page for the 'user' model.
In the search($params) method inside of the UserSearch model, I used the following code to join the above tables together
$query = User::find()->with('role');
Everything works fine with the query.
By default Gii does not include the data from the joined table 'role' in the GridView::widget inside of the views/user/index.php page. With the join query above I could retrieve data from both tables. In the views/user/index.php page I have injected the GridView::widget with the following code so that it also includes the data and column names from the joined table (role).
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'userid',
'username',
'role.role_name',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
Everything works fine with the role data 'role_name included in the GridView::widget. But the problem is that there is no search box for the role_name. The GridView::widget creates search box for the User properties only. Is there any way to add search box for the properties of the joined table 'role' because I also would like to search through 'role_name' as well as through other properties of the User model.

Answer 1

Try this way:
In your UserSearch model add
UserSearch extends ...
{
public $roleFilterInputName; //the name of the filter search input
//important
function rules()
{
//add roleFilterInputName as safe
return [
[['xxx', 'roleFilterInputName'], 'safe'], //!!!!
];
}
}
in your grid:
'columns':
[
//...
[
'attribute' => 'roleFilterInputName',
'value' => 'role.role_name'
],
//...
]
in UserSearch::search()
$query->andFilterWhere(['like', 'role.role_name', $this->roleFilterInputName])
But I guess you'll have to use 'joinWith' instead of 'with'.

Inside CGridView add below code. It will enable filter with dropDownList.
[
'attribute' => 'act_role_id',
'label' => 'Actor Role',
'value' => 'actRole.role_name',
'filter' => yii\helpers\ArrayHelper::map(app\models\ActorRole::find()->orderBy('role_name')->asArray()->all(),'act_role_id','role_name')
],
CGridView code Snippet is as below:
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'userid',
'username',
[
'attribute' => 'act_role_id',
'label' => 'Actor Role',
'value' => 'actRole.role_name',
'filter' => yii\helpers\ArrayHelper::map(app\models\ActorRole::find()->orderBy('role_name')->asArray()->all(),'act_role_id','role_name')
],
['class' => 'yii\grid\ActionColumn'],
],
]); ?>

Answer 3

Try it with
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'userid',
'username',
//'role.role_name',
['attribute' => 'role', 'value' => 'role.role_name'],
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
I just have tried it in my code, so I'm not sure if this works also with your code. But if so, I don't know why it has to be defined this way.
I guess the answer of rajesh ujade also includes this definition, however, for Yii 1.

Answer 4

This worked for me
Table = Lead (id , year_id)
Table = Year (id, text)
Added text in lead (index.php)
Year::find()->all() = This code pull all value from table/ all years.
[
'attribute'=> 'year_id',
'format' => 'html',
'value' => 'year.value',
'label' => 'Year',
'filter' => Html::activeDropDownList($searchModel, 'year', yii\helpers\ArrayHelper::map(Year::find()->all(), 'year_id', 'value'), ['class' => 'form-control', 'prompt' => '---']),
],
Also it shows dropdown as well sorting.

#Ekonoval is going in right way.
Just add following in serch function of UserSearch:
After initializing ActiveDataProvider object like this:
$dataProvider = new ActiveDataProvider([
'query' => $query,
'pagination' => [
'pageSize' => 5,
],
]);
$dataProvider->sort->attributes['roleFilterInputName'] = [
'asc' => ['role.role_name' => SORT_ASC],
'desc' => ['role.role_name' => SORT_DESC]
];

Answer 6

You may write query in your UserSearch model like
if($this->role)
{
$query->join('LEFT JOIN','role','role.user_id = user.id')->andFilterWhere(['role.item_name' => $this->role]);
}
