Laravel is a feature-rich framework. However, you cannot find all the available features in the official documentation. Here are some features that you may not know.
- Get original attributes
After mutating an Eloquent record you can get the original attributes by calling
getOriginal()$user = App\User::first(); $user->name; //John$user->name = "Peter"; //Peter$user->getOriginal('name'); //John $user->getOriginal(); //Original $user record
2. Check if Model changed
Determine if the model or given attribute have been modified using
isDirty()$user = App\User::first(); $user->isDirty(); //false$user->name = "Peter"; $user->isDirty(); //true
You can also check if a particular attribute is changed.
$user->isDirty('name'); //true
$user->isDirty('age'); //false
3. Get changed attributes
Retrieve the changed attributes of a model using
getChanges()$user->getChanges()//[ "name" => "Peter", ]
Note: Changes will reflect only if you save the model or sync the changes usingsyncChanges()
4. Custom
deleted_at column
By default, Laravel handles soft deletes using
deleted_at column. You can change this by explicitly defining the DELETED_AT property.class User extends Model
{
use SoftDeletes;
* The name of the "deleted at" column.
*
* @var string
*/
const DELETED_AT = 'is_deleted';
}
Or by defining an accessor.
class User extends Model
{
use SoftDeletes;
public function getDeletedAtColumn()
{
return 'is_deleted';
}
}
5. Save models and relationships
You can save a model and its corresponding relationships using the
push()method.class User extends Model { public function phone() { return $this->hasOne('App\Phone'); } }$user = User::first(); $user->name = "Peter";$user->phone->number = '1234567890';$user->push(); // This will update both user and phone record in DB
6. Reload fresh model
Reload a fresh model instance from the database using
fresh()$user = App\User::first(); $user->name; // John// user record get updated by another thread. eg: 'name' changed to // Peter.$updatedUser = $user->fresh(); $updatedUser->name; // Peter$user->name; // John
7. Reload existing model
You can reload an existing model with fresh values from database using
refresh()$user = App\User::first(); $user->name; // John// user record get updated by another thread. eg: 'name' changed to // Peter.$user->refresh(); $user->name; // Peter
Note:refresh()will also update the loaded relations of the existing model.
8. Check if models are the same
Determine if two models have the same ID and belong to the same table using
is()$user = App\User::find(1); $sameUser = App\User::find(1); $diffUser = App\User::find(2);$user->is($sameUser); // true $user->is($diffUser); // false
9. Clone a model
You can clone a model using
replicate(). It will create a copy of the model into a new, non-existing instance.$user = App\User::find(1); $newUser = $user->replicate();$newUser->save();
10. Specify attributes in
find() method
When using
find() or findOrFail() methods you can specify the attributes to select as the second argument.$user = App\User::find(1, ['name', 'age']);$user = App\User::findOrFail(1, ['name', 'age']);
