Getting extra fields from laravel api having belongstomany relationship

Question

I have two data tables related to each other by the belongstomany relationship. And when I am fetching data from its api controllers with selecting only two column keys ['id','title'] yet it returns some extra data in the response object.

model code:

public function place(){

    return $this->belongsToMany(Place::class,'city_place')->select(array('id', 'title'));

}

controller code:

public function ofcity($id)
{
    $city=City::findOrFail($id);
    return new CityResource(  $city->place()->get());

}

enter image description here

Answer 1

You must indicate the name of the table in front of the fields.

model Place code:

protected $columns = ['places.id', 'places.title']; //all column for select

public function scopeExclude($query, $value = [])
{
    return $query->select(\array_diff($this->columns, (array) $value));
}

model City code:

public function place()
{        
     return $this->belongsToMany(Place::class,'city_place', 'city_id', 'place_id');        
}

controller code:

public function ofcity($id)
{
    $cities = City::findOrFail($id)->place()->exclude(['featured_image'])->get()->toArray();
    return response()->json(['cities' => $cities], 200);    
}

In exclude skip all the fields that need not to be shown.

Answer 2

Thanks everyone here helping me out but none of the above solution worked..I figured it out after trying different functions and spending hours on this.

model Place code:

public function place(){

    return $this->belongsToMany(Place::class,'city_place','city_id','place_id')->select(array('places.id', 'places.title'));

}

controller code:

public function ofcity($id) { $city=City::findOrFail($id);

return new CityResource( $city->place()->get()->map(function ($item,$key) {

 return ['id' => $item['id'],'title'=>$item['title']];
    })

    );
