How to Exclude Certains Columns While Using Eloquent

How to exclude certains columns while using eloquent

If you only need to hide attributes from your model's array or JSON representation, you may use one or both approaches:

Add the
$hidden property to your model

class User extends Model
{
    /**
     * The attributes that should be hidden for arrays.
     */
     protected $hidden = ['password'];
}

Use the
makeHidden
function

$users = $users->makeHidden(['address', 'phone_number']);

See other answers for more details... But sometimes you don't want to load huge data (geospatial, html, logs...) into your application, it will be slow and take more memory. OP asked for an SQL query hence my answer, but most of the time it's more convenient to only hide the data from the JSON response.

AFAIK there is no build in option in SQL to exclude columns explicitly, so Laravel can't do it. But you can try this trick

Update

Another trick is to specify all columns in your model (or use an extra query to get all columns using $this->getTableColumns() from this answer, it can also be cached after each migration to avoid two queries) then add a local scope function

// The below code requires you to define all columns in $columns.
// A better approach is to query the schema of the table and cache it after each  
// migration, for more details: https://stackoverflow.com/a/56425794/3192276

protected $columns = ['id','pseudo','email'];

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

Then you can do :

$users = User::where('gender', 'M')
    ->where('is_active', 1)
    ->exclude(['pseudo', 'email', 'age', 'created_at'])
    ->toArray();

One option you have is to exclude the Hotel's you don't want in your list at the query level:

Hotel::whereNotKey($group->hotels->modelKeys())->get();

How to exclude the relation column from the collection result array- eager loading

On the first try, every child will have category_id, not the primary array.

collect($result)->map(function($item) {
    return collect($item)->except('category_id');
})->toArray();

On the second one, you're using toArray() in your main array so to unset category_id you need to use the []

unset($i['category_id']);

PS: I see paginate() it's the result of this the result of an endpoint? In that case, you can check out API Resource.

Laravel 5 Model: Do not include certain columns in Eloquent

You can use the $hidden property on your Eloquent model:

class CmsUserInformation extends Model
{
    protected $hidden = [
        'id',
        'users_id',
        'created_at',
        'updated_at',
    ];
}

This will automatically exclude the given attributes when the models are ultimately serialized.

If you only want to hide it in a specific instance, use the setHidden method:

$info = CmsUserInformation::where('users_id', Auth::id())->first();

$info->setHidden([
    'id',
    'users_id',
    'created_at',
    'updated_at',
]);

Laravel Replicate Certain Columns to Another Table

If you know which fields you want to keep between the two models:

$fatherOrigin = \App\FatherRegistrars::where('id', $fatherID)->first();
$fieldsToKeep = [ 'name', 'email', ... etc ... ];

$father = new \App\User(); 
foreach($fieldsToKeep as $field) {
   $father->$field = $fatherOrigin->$field;
}

If you know which field you want to discard:

$fatherOrigin = \App\FatherRegistrars::where('id', $fatherID)->first();
$fieldsToDiscard = [ 'birth', 'religion', ... etc ... ];
$originData = $fatherOrigin->toArray();

foreach($fieldsToDiscard as $field) {
   unset($originData[$field]);
}

$father = \App\User::firstOrCreate($originData);

How to hide relationship columns in laravel?

If you don't want to hide the phone_no for all the requests by adding it to the hidden property, you could do something like this:

$user = App\User::with('client')->find(2);
$user->client->makeHidden('phone_no');
return $user;

As I stated in my comment to the original question: I found this method as well. I believe this should be the method you should use when you want to exclude columns more often. If you only want to exclude a column once, my solution should be sufficient.
