laravel eloquent query with relations - mysql

Question

I'm trying to replace a mysql query with laravel eloquent. This is my structure.
Consumers Table
---------------
id, email, name
Transactions Table
-------------------
id, consumer_id, value, bonus_value
Output that I'm trying to achieve
id, email, name, total_value
1, abc#123.com, Al, 11000
2, abc2#123.com, Bl, 200000
This is what I have added in Consumer.php
/**
* Transactions Relationship
*
* #return \Illuminate\Database\Eloquent\Relations\HasMany
*/
public function transactions(){
return $this->hasMany(Transaction::class, 'consumer_id');
}
And this is the query I've written so far.
$query = Consumer::query()
->join('consumer_transactions AS ct', function($q) {
$q->on('consumers.id', '=', 'ct.consumer_id')
->where('ct.status', 'processed')
->where('ct.approved', 1)
->select(DB::raw('SUM(ct.value + ct.bonus_value) AS total_points'))
;
})
->whereIn('consumers.id', $consumerIds)
->get()
;
It doesn't return total_points

Answer 1

Join Clause that passed to your join take Illuminate\Database\Query\JoinClause witch doesn't have a method called 'select'.
you select should be out of join clause.
$query = Consumer::query()
->join('consumer_transactions AS ct', function($q) {
$q->on('consumers.id', '=', 'ct.consumer_id')
->where('ct.status', 'processed')
->where('ct.approved', 1);
})
->select( ['consumers.*', DB::raw('SUM(ct.value + ct.bonus_value) AS total_points')])
->whereIn('consumers.id', $consumerIds)
->get();

Answer 2

I'm not fun of joining tables. That's why I can offer you a different approach.
$consumers = Consumer::whereIn('id', $consumerIds)
->with(['transactions' => function($query) {
$query
->where('startus', 'processed')
->where('approved', 1)
}])->get()
->map(function($item, $key) {
return $item->total_points = $item->transactions->value + $item->transactions->bonus_value
});
