我使用一些$query->andFilterWhere(...)
来创建我的查询。
可以通过echo $query->createCommand()->rawSql;
当我复制最终查询并在phpmyadmin上过去时,获取了2条记录但在ActiveDataProvider中找不到结果。
我错过了哪一点?!
============================================
这是我的代码:
$query = Camera::find();
$post = Yii::$app->request->post();
$post2 = array_filter((array)$post);
if( count($post2) >0 ){
foreach($post2 as $k=>$v){
$query->andFilterWhere([ 'Like' , $k , $v ]);
}
}
if($post['State'] > 0){
$branches = Branch::find()->joinWith('city')->where('state_id='.((int)$post['State']))->all();
foreach( $branches as &$v){
$v = $v->brch_id;
}
$query->andFilterWhere([ 'IN' , 'brch_id' , $branches ]);
}
echo $query->createCommand()->rawSql;
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
答案 0 :(得分:1)
问题在于这个循环:
foreach( $branches as &$v){
$v = $v->brch_id;
}
我只需将其替换为:
$a = [];
foreach( $branches as $v){
$a[] = (int)$v->brch_id;
}
并完成,解决了!!!!! :|

在您的代码中
if( count($post2) >0 ){ // that means all fields filled
foreach($post2 as $k=>$v){
$query->andFilterWhere([ 'Like' , $k , $v ]);
}
}
在此之后,您检查了$post['State']
,并将其用于joinWith
。我不知道您正在使用什么样的搜索(或者您构建的是什么形式),但似乎您在这两个模型中都在搜索State
...这是正确的行为吗?
如果这是正确的,您能否向我们展示适合您的原始SQL查询,而不是ActiveDataProvider
?
我可以问为什么不使用课程进行此搜索并将其从Camera
扩展?
这与此类似:
public $state // fields that you Camera model don't have.
public function search($params){
$query = Camera::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
if (!($this->load($params) && $this->validate())) {
return $dataProvider;
}
$query->andFilterWhere('like', 'attribute', $this->attribute);
// same for the others attributes here...
$query->joinWith(['nameOfRelationWithBranch' => function ($queryBranch) {
$queryBranch->joinWith(['city' => function ($queryCity) {
$queryCity->andFilterWhere('state_id', $this->state);
}]);
}]);
//echo $query->createCommand()->rawSql;
return $dataProvider;
}
