How to use relations using joinWith in yii2 search model - yii2

Question

I have two models with related data fbl_leagues and fbl_country tables. fbl_leagues have a column country_id which is related to fbl_country, now in yii2 gridView i was able to do something like [
'attribute' => 'country_id',
'value' => 'country.name',
], which gives the name of the country rather than the countries id, then i also want to enable searching by country name rather than country_id but i get the below error
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'country.name' in 'where clause'
The SQL being executed was: SELECT COUNT(*) FROM `fbl_leagues` LEFT JOIN `fbl_country` ON `fbl_leagues`.`country_id` = `fbl_country`.`id` WHERE `country`.`name` LIKE '%s%'
Below is my LeagueSearch model
class LeagueSearch extends League
{
/**
* {#inheritdoc}
*/
public function rules()
{
return [
[['id', 'created_at', 'updated_at'], 'integer'],
[['name','country_id'], '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 = League::find();
$query->joinWith('country');
// 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,
'created_at' => $this->created_at,
'updated_at' => $this->updated_at,
]);
$query->andFilterWhere(['like', 'name', $this->name])
->andFilterWhere(['like', 'country.name',$this->country_id]);
return $dataProvider;
}
}
and my league model
{
return [
[['country_id', 'created_at', 'updated_at'], 'integer'],
[['name','country_id'], 'required'],
[['name'], 'string', 'max' => 100],
[['country_id'], 'exist', 'skipOnError' => true, 'targetClass' => Country::className(), 'targetAttribute' => ['country_id' => 'id']],
];
}
/**
* {#inheritdoc}
*/
public function attributeLabels()
{
return [
'id' => Yii::t('app', 'ID'),
'country_id' => Yii::t('app', 'Country Name'),
'name' => Yii::t('app', 'Name'),
'created_at' => Yii::t('app', 'Created At'),
'updated_at' => Yii::t('app', 'Updated At'),
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getCountry()
{
return $this->hasOne(Country::className(), ['id' => 'country_id']);
}
/**
* #return \yii\db\ActiveQuery
*/
public function getPerfectSelections()
{
return $this->hasMany(PerfectSelection::className(), ['league_id' => 'id']);
}
Now i noticed that when i comment out $query->joinWith('country'); then there will be no error but searching not working as expected

Answer 1

Hmm silly me i guess i later figure out the problem the table name is fbl_country so i suppose write fbl_country.name but wrote country.name in my search model, it's being a long day though, thanks for all
