There are a couple of "parameters" of an Eloquent model, as properties of that class. The most mainstream ones are presumably these: class User extends Model { protected $table = 'users'; protected $fillable = ['email', 'password']; // these fields can be filled with User::create() method protected $dates = ['created_at', 'deleted_at']; // these fields can be disabled protected $appends = ['field_1', 'field_1']; // additional values returned...

Many times you need to check against some condition for records returned by relationship in Laravel Eloquent. For example you only want a list of users which are approved or verified. Normally we do it this way : public function list_users() { return $this->hasMany('App\User'); } Then for returned users you need to iterate the list and check if it is approved or not. But there is a short and easy way to do it: public...

Eloquent has some functions that combine two methods, like “please do this, otherwise do that”. findOrFail(): If you want to do one task otherwise another then do it like this: $record = Record::findOrFail($id); Instead of: $record = Record::find($id); if (!$record) { abort (404); } firstOrCreate(): If you want to create a record but only if it does not exist already in database, then do it like this: $record = Record::firstOrCreate(['name' => $name]); Instead of: $record = Record::where('name', $name)->first(); if (!record) { Record::create([ 'name' => $name ]);} ...

Many times while working on a project, we need to increment value of certain columns in database. Laravel is shipped with some semi-hidden function to do various tasks. One of those are methods to perform increment or decrement on database columns. Normally we do the increments and decrements this way: $post = Post::find($post_id); $post->read_count++; $post->save();   But with Laravel eloquent methods we can do this: $post = Post::find($article_id); $post->increment('read_count');   Another way of doing this can be: Post::find($post_id)->increment('read_count'); Post::find($post_id)->increment('read_count', 5); // +5 Product::find($produce_id)->decrement('stock'); // -1 Product::find($produce_id)->decrement('stock',5); // -5 ...
