[['attachment'], 'required'],
[['deductible'], 'string', 'max' => 100],

here's my search model
public function rules()
{
return [
[['id', 'policy_num', 'attachment', 'id_client', 'delete_on','created_by', 'updated_by', 'printed_at'], 'integer'],
[['cover_rate'], 'number'],
[['start_date','end_date','created_at','updated_at'], 'date','format'=>'yyyy-mm-dd'],
];
}
public function search2($params)
{
$query = AskPolicy::find();
$query->joinWith(['client'])->where(['id_client'=>Yii::$app->user->identity->id_client]);
$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;
}
$query->andFilterWhere([
'id' => $this->id,
'policy_num' => $this->policy_num,
'ask_policy.created_at' => $this->created_at,
'ask_policy.updated_at' => $this->updated_at,
'printed_at' => $this->printed_at,
]);
// $query->andFilterWhere(['>=', 'ask_policy.created_at', $this->start_date]);
// $query->andFilterWhere(['<=', 'ask_policy.created_at', $this->end_date]);
$query->andFilterWhere(['like',"(date_format(FROM_UNIXTIME(`created_at` ), '%Y-%m-%d' ))", $this->start_date])
->andFilterWhere(['like', "(date_format(FROM_UNIXTIME(`updated_at` ), '%Y-%m-%d' ))", $this->end_date]);
return $dataProvider;
}
if i use below code : search start date and end date not working
$query->andFilterWhere(['>=', 'ask_policy.created_at', $this->start_date]);
$query->andFilterWhere(['<=', 'ask_policy.created_at', $this->end_date]);
how to the best way convert integer datetime in Yii2 for date range search ? i was searching but not find tutorial with good explanation.

Answer 1

your query is joined with client and both models has created_at field.
you can set alias for current model with
$query->alias('t');
and alias joined table with
$query->joinWith(['client as cli']);
then if you want to use created_at from main model you can use t.created_at and if you want to use created_at from joined model you can use cli.created_at.

Answer 2

you have not given table alias try like this
$query->andFilterWhere(['like',"(date_format(FROM_UNIXTIME(ask_policy.`created_at` ), '%Y-%m-%d' ))", $this->start_date])
->andFilterWhere(['like', "(date_format(FROM_UNIXTIME(ask_policy.`updated_at` ), '%Y-%m-%d' ))", $this->end_date]);
