Rails & Laravel comparisons

Start console

# rails

bundle exec rails c

# laravel

php artisan tinker

New instance

user = User.new
user.email = 'example@hopsie.com'
user.save

# or

user = User.create(email: 'example@hopsie.com')

Laravel will alias the shorthand, such as User to App\Models\User so these examples will just use the aliased version.

$user = new User;
$user->email = 'example@hopsie.com';
$user->save();

Find by ID

user = User.find(1)

$user = User::find(1);

Find by attribute

user = User.find_by(email: 'example@hopsie.com')

# or

user = User.where(email: 'example@hopsie.com').first

$user = User::where('email', 'example@hopsie.com')->first();

Find by multiple attributes

aprroved_admins = User.where(admin: true, approved: true)

$approved_admins = User::where('admin', true)->where('approved', true)->get();

Update instance

user = User.find(1)
user.update(email: 'example@sidesea.com')

# or

user.email = 'example@sidesea.com'
user.save

$user = User::find(1);
$user->update(['email'=>'example@sidesea.com']);

# or

$user->email = 'example@sidesea.com';
$user->save();

Delete

user = User.find(1)
user.destroy

$user = User::find(1);
$user->delete();

Collection all

users = User.all

$users = User::all();

Collection first & last

users = User.all
first_user = users.first
last_user = users.last

$users = User::all();
$first_user = $users->first();
$last_user = $users->last();

Count

User.count

User::count();

Pluck attribute

emails = User.all.pluck(:email)

$emails = User::all()->pluck('email');

Associations has_many

# has_many :posts

user = User.find(1)
posts = user.posts

# public function posts() { $this->hasMany('App\Models\Post'); }

$user = User::find(1);
$posts = $user->posts;

Associations belongs_to

# belongs_to :user

post = Post.find(1)
user = post.user

# public function user() { return $this->belongsTo('App\Models\User'); }

$post = Post::find(1);
$user = $post->user();

Collection loop

users = User.where(name: 'Rails')
users.each do |user|
  user.name = 'Ruby on Rails'
  user.save
end

$users = User::where('name', 'Laravel')->get();
foreach ($users as $user) {
  $user->name = 'Laravel PHP Framework';
  $user->save();
}
