how to return object instead of object in array

Question

I am trying to return a response of an object which came from a collection array due to a relation of hasMany.

I have tried to do a return $block->where('date','=',$today)->first();

error said: Call to undefined method App\BlockDate::addEagerConstraints()

public function block_dates() 
{
    return $this->hasMany(BlockDate::class);
}

public function schedule_block() 
{
    $today = Carbon::today()->toDateString();
    $block = $this->block_dates();

    return $block->where('date','=',$today)->first();
}

schedule_block() should return an object of BlockDate. If I remove first(), it returns an array with the desired object in. I would like to just retrieve the object based on the relation. Any help is appreciated.

Add ->toArray() at the end may be that helps to convert object into array — Niket Joshi

@Ijas schedule_block() is called from a controller with a with() Joshi - I am trying to get the object, not to make it into an array — NewProgrammer

try this one :

public function schedule_block() {
    $today = Carbon::today()->toDateString();
    return $this->hasOne(BlockDate::class)->where('date','=',$today);
}

@NewProgrammer , is it working ? or you receives any errors ?

NewProgrammer Over a year ago

yes it is working, but I am confused. Relation hasOne does not point to the first entry of BlockDates with schedule_id, which I thought it will. How does it work?

Saurabh Mistry Over a year ago

block_dates() uses hasMany relation with BlockDate class , which will return array() , but as you want to get only one record as object , so i used hasOne relationship with BlockDate class , which will return Object.

technically Schedule class hasMany relation with BlockDate class, yes which is why it returns an array. I am just puzzled at how where() works for hasOne. Thank you for clarifying.

where will also work with hasMany , but it will return results as array not object
