I want to sum up a field in cakephp 3.2. But the field is present in hasOne model association.
I want to do it in the bind query .
I have a order table and i am doing model bind with collection table .
Here i want to sum up all the due_amount in collections table
I have tried but its not working.
Please check my code,Is there any thing wrong with it.?
$this->Orders->hasOne('Collections', [
'className' => 'Collections',
'foreignKey' => 'order_id',
'strategy' => 'select',
'conditions' => function (\Cake\Database\Expression\QueryExpression $exp, \Cake\ORM\Query $query) {
$query->order(['Collections.id' => 'ASC']);
return [];
}
]);
$get_total_sales = $this->Orders->find('all')->where($condition)->select(['id', 'region_id', 'net_total'])->contain(['Collections' => ['queryBuilder' => function ($q) {
return $q->select(['id', 'order_id', 'total_sale_amount', 'due_amount']);
}]])->order(['Orders.due_date DESC']);
$res2 = $get_total_sales->select(['total_due' =>$get_total_sales->func()->sum('collection.due_amount')])->first();
echo $due = $res2->total_due;//its showing column not find error.
Is it working in order table instead of collections table?
How can i do it for collection table using the $get_total_sales listing results?
Below some out put
[
{
"id": 40,
"region_id": 2,
"net_total": 2899.12,
"collection": {
"id": 182,
"order_id": 40,
"total_sale_amount": 2899.12,
"due_amount": 1990
},
},
{
"id": 38,
"region_id": 2,
"net_total": 110,
"collection": {
"id": 181,
"order_id": 38,
"total_sale_amount": 110,
"due_amount": 10
},
},
{
"id": 39,
"region_id": 2,
"net_total": 16670,
"collection": {
"id": 190,
"order_id": 39,
"total_sale_amount": 16670,
"due_amount": 16630.99
},
},
Here i want to sum up all the due_amount in collections table
Thank you
