Selectet data and data from with(), Laravel - eloquent

Question

I want to select some columns and some data from with(), the problem is that I get only data from select().
$today = date('Y-m-d', strtotime('-7 days'));
$contracts = Contract::select('
'contracts.id',
'contracts.contract_value_exc_VAT_total',
'customers.account_name',
'users.name',
)
->whereHas('dates', function($q) use($today){
return $q->whereDate('date', '>=', $today)
->where(function($q) {
$q->where('lkp_contract_date_tag_id', 4)
->orwhere('lkp_contract_date_tag_id', 7);
});
})
->with(['dates' => function($q){
$q->select('id', 'date');
}])
->join('customers','contracts.customer_id', 'customers.id')
->leftJoin('users','contracts.account_manager_select', 'users.id')
->get();
return response()->json($contracts);
From response, dates are null
//date....
dates: []
//date...

You can do it without using the select()
You can have the relations in the ContractModel. You can always process the data after getting from the database and manipulate it in a format you want to return.
There are two options to do that
Do it here in the controller itself.
Create an API resource for the Contract. (https://laravel.com/docs/7.x/eloquent-resources#introduction)
I would suggest the latter as it's more convenient.
For both of them you need to do this first. Make some changes in the contract model.
ContractModel.php
// I'm assuming that you have dates relation in the contract(because you've added it in the `with()` for eager loading.)
public function dates(){
...
}
// Instead of joining while doing the query, add the following
// relations in the contract as well.
public function customer(){
return $belongsTo('App\Customer', 'customer_id', 'id');
}
public function accountManagerSelect(){
return $belongsTo('App\User', 'account_manager_select', 'id');
}
This is how you go with the API resource approach.
Create the Contract Api Resource. And this is how the toArray() method should be.
toArray() {
// Get the dates in the format you want. I'have added the below
// format by considering the 'select' statement you added for
// dates.
$dates = [];
// will use the relation dates, to get the associated dates.
foreach($this->dates as $date){
array_push($dates, [
'id' => $date->id,
'date' => $date->date,
]);
}
return [
'id' => $this->id, // id of the contract.
'contract_value_exc_VAT_total' => $this
->contract_value_exc_VAT_total,
'account_name' => $this->account_name,
// This will use the accountManagerSelect relation to get the
// User instance and then you can access the name from that.
'name' => $this->accountManagerSelect->name,
'dates' => $dates, // The dates variable that we created earlier.
];
}
All you need to do is return using API resource in your controller.
instead of doing this
return response()->json($contracts);
Use Api resource
return ContractResource::collection($contracts);
