Answer 1

The search field disappears because in not setted properly in searchModel ..
for this you must extend the related modelSeacrh adding the relation with the related model and the filter for the field you need ..
for this you must set in the base mode, the relation
public function getSale()
{
return $this->hasOne(Sale::className(), ['id' => 'sale_id']);
}
/* Getter for sale data */
public function getSaleData() {
return $this->sale->data;
}
then setting up the search model declaring
/* your calculated attribute */
public $date;
/* setup rules */
public function rules() {
return [
/* your other rules */
[['data'], 'safe']
];
}
and extending
public function search($params) {
adding proper sort, for data
$dataProvider->setSort([
'attributes' => [
.....
'data' => [
'asc' => ['tbl_sale.data' => SORT_ASC],
'desc' => ['tbl_sale.data' => SORT_DESC],
'label' => 'Data'
]
]
]);
proper relation
if (!($this->load($params) && $this->validate())) {
/**
* The following line will allow eager loading with country data
* to enable sorting by country on initial loading of the grid.
*/
$query->joinWith(['sale']);
return $dataProvider;
}
and proper filter condition
// filter by sale data
$query->joinWith(['sale' => function ($q) {
$q->where('sale.data = ' . $this->data . ' ');
}]);
Once you do al this the searchModel contain the information for filter and the search field is showed in gridview
