Eloquent update1/8/2024 You can use a shorter method: $user->touch() Īnother case – sometimes you want to not only set updated_at of current Eloquent model, but also it’s parent record by relationship.įor example, if some comment was updated, then you want to consider that post record should have new updated_at, too. Opposite of the last example – maybe you want to set new value to ONLY updated_at column, and not change others. Then, you need to do the same as above – disable timestamps, but only for that one time: $user = User::find(1) Whenever you update Eloquent record, it automatically saves current timestamp into updated_at column, and that’s a great feature.īut sometimes you want to avoid it, like you increment some value and don’t want to consider it as “full record update”. For example, if you want to use updated_at, you can do this: $lastUpdatedUser = User::newest('updated_at')->first() User::oldest()->get() Īlso, you can specify another column to order by. There is an opposite method oldest() which would order by created_at ascending. Laravel default provides Eloquent updateOrCreate() method. We use Laravel Eloquent use updateOrCreate() Query functionality. updateOrCreate method is used to check if the record exists then it will update otherwise new record is created. You can do it quicker: User::latest()->get() īy default, latest() will order by created_at. Laravel eloquent added amazing method call updateOrCreate(). Instead of: User::orderBy('created_at', 'desc')->get() There are two “shortcuts” to order data by timestamps. Order by Timestamp with latest() and oldest() Return $this->belongsToMany(Role::class)->withTimestamps() ĥ. And Laravel doesn’t try to fill in created_at/updated_at in this case.īut if you do want to save the timestamps automatically, you need to add them into migration file, and then define relationship using ->withTimestamps() public function roles() Return $this->belongsToMany(Role::class) Īnd then, when you want to add a role to a user, you would do something like this: $roleID = 1 īy default, those pivot tables don’t contain timestamps. In the model, you would define relationship like this: class User extends Model Many-to-Many: Pivot Table with TimestampsĪ bit of exception for timestamps automation is when you create a pivot table in many-to-many relationships, like table role_user between users and roles tables. * The storage format of the model's date columns.Ĥ. This property determines how date attributes are stored in the database, as well as their format when the model is serialized to an array or JSON: class Flight extends Model If you need to customize the timestamp format, set the $dateFormat property on your model. From Laravel 7, dates serialized using the new format will appear like: T20:01:00.283041Z. Here, I will just quote official Laravel documentation:īefore Laravel 7, dates would be serialized to a format like the following: 20:01:00. Luckily, you can specify them in the model, too: class Role extends Model What if you’re working with non-Laravel database and your timestamp columns are named differently? Maybe, you have create_time and update_time. To disable that automatic timestamps, in your Eloquent Model you need to add one property: class Role extends Model Laravel would try to automatically fill in created_at/updated_at and wouldn’t find them. If your DB table doesn’t have those fields, and you will try to do something like Model::create($arrayOfValues) – you will get SQL error. But there’s plenty of things you can do to customize them or perform some interesting operations. * Get the primary key value for a save query.By default, Laravel Eloquent models assume your table has timestamp fields – created_at and updated_at. $query->where($keyName, '=', $this->getKeyForSaveQuery($keyName)) Return parent::setKeysForSaveQuery($query) Protected function setKeysForSaveQuery(Builder $query) * \Illuminate\Database\Eloquent\Builder $query Laravel Model with Two Primary Keys update (Code Answer) Laravel Model with Two Primary Keys update protected $primaryKey =
