1. Check if Model changed
You must keep look or identify if the model has been updated using isDirty()
$user = App\User::first();
$user->isDirty(); //false
$user->name = “Peter”;
$user->isDirty(); //true
If the individual attribute has been changed, you can also check.
$user->isDirty(‘name’); //true
$user->isDirty(‘age’); //false
2. Get original attributes
Once you develop the eloquent record and if you need original attributes, Just call getOriginal()
$user = App\User::first();
$user->name; //John
$user->name = “Peter”; //Peter
$user->getOriginal(‘name’); //John
$user->getOriginal(); //Original $user record
3. Get changed attributes
If you want to undo the changed attributes of a model, do it by using getChanges()
$user->getChanges()
//[
“name” => “Peter”,
]
Note: Here you need to keep in mind that, you will only get changes back if you save it or sync the changes with syncChanges()
4. Custom deleted_at column
In Laravel, the default deleted_at column is used for deleting, if you wish to change it, you need to define 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 relationships and models
By using the push() method, you can save the relationships and models.
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
By using fresh(), you can Reload a fresh model
$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
By using the refresh(), we can reload existing models along with fresh value.
$user = App\User::first();
$user->name; // John
// user record get updated by another thread. eg: ‘name’ changed to // Peter.
$user->refresh();
$user->name; // Peter
8. Check if models are the same
You can identify if the models are same by 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
With replicate(), you can clone a model. It helps you to create a copy and non-existing model instance.
$user = App\User::find(1);
$newUser = $user->replicate();
$newUser->save();
10. Specify attributes in find() method
Use find() or findOrFail() methods, to identify the attributes for selecting the second argument.
$user = App\User::find(1, [‘name’, ‘age’]);
$user = App\User::findOrFail(1, [‘name’, ‘age’]);
