Yii2 how does search() in SearchModel work?
I would like to be able to filter a GridView column of relational data. This is what I mean:
I have two tables, TableA and TableB. Both have corresponding models generated using Gii. TableA has a foreign key to a value in TableB, like this:
TableA
attrA1, attrA2, attrA3, TableB.attrB1
TableB
attrB1, attrB2, attrB3
attrA1 and attrB1 are the primary keys of their corresponding tables.
Now, I have a Yii2 GridView of attrA2, attrA3 and attrB2. I have a working filter on attrA2 and attrA3 so that I can search on column values. I also have a working sort for these two columns too - by just clicking on the column header. I would like to be able to add this filtering and sorting on attrB2 too.
My TableASearch model looks like this:
public function search($params){
$query = TableA::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
if (!($this->load($params) && $this->validate())) {
return $dataProvider;
}
$this->addCondition($query, 'attrA2');
$this->addCondition($query, 'attrA2', true);
$this->addCondition($query, 'attrA3');
$this->addCondition($query, 'attrA3', true);
return $dataProvider;
}
In my TableA model, I set the related value like this
public $relationalValue;
public function afterFind(){
$b = TableB::find(['attrB1' => $this->attrB1]);
$this->relationalValue = $b->relationalValue;
}
Although it is probably not the best way of doing this. I think I have to use $relationalValue somewhere in my search function but I'm not sure how. Similarly, I would like to be able to sort by this column too - just like I can for attrA2 and AttrA3 by clicking on the header link`. Any help would be appreciated. Thanks.
