教材

若干古そうだがこれ 2019 April
Laravel5.2あたりの言及が多いのでベースが古いっぽいものの基礎のお勉強なので大丈夫そう
たまに動かないコードがあったりはする
（追記）読み終わったものの良書だったと思う。6系の言及もあったりで、一応publishの時期で更新はされていそう。最新の話題は勿論ないものの、基礎を学ぶには十分だった

https://learning.oreilly.com/library/view/laravel-up/9781492041207/

後で調べたい

  • signedRoute
  • Custom Route Model Binding
  • view composer
  • when/unless(eloquent)
isopppisoppp

Route/Controller

__invokeで単発function

// \App\Http\Controllers\UpdateUserAvatar.php
public function __invoke(User $user)
{
    // Update the user's avatar image
}

productionでは php artisan route:cache をするべし？

abort

Route::post('something-you-cant-do', function (Illuminate\Http\Request $request) {
    abort(403, 'You cannot do that!');
    abort_unless($request->has('magicToken'), 403);
    abort_if($request->user()->isBanned, 403);
});

Column Types
https://laravel.com/docs/8.x/migrations#available-column-types

Index

// After columns are created...
$table->primary('primary_id'); // Primary key; unnecessary if used increments()
$table->primary(['first_name', 'last_name']); // Composite keys

Databases and Eloquent ( Query Builder )

basics

// Basic statement
DB::statement('drop table users');

// Raw and parameter binding
DB::select(
    'select * from users where type = ?',
    [$type]
);
DB::select(
    'select * from users where type = :type',
    ['type' => $userType]
);
DB::insert(
    'insert into contacts (name, email) values (?, ?)',
    ['sally', 'sally@me.com']
);
DB::update(
    'update contacts set status = ? where id = ?',
    ['donor', $id]
);
DB::delete(
    'delete from contacts where archived = ?',
    [true]
);

// Select using the fluent builder
$users = DB::table('users')->get();

// Joins and other complex calls
DB::table('users')
    ->join('contacts', function ($join) {
        $join->on('users.id', '=', 'contacts.user_id')
             ->where('contacts.type', 'donor');
    })
    ->get();

more complex

// where where
DB::table('contacts')
    ->where('vip', true)
    ->where('created_at', '>', now()->subDay());

// orWhere
DB::table('contacts')
    ->where('vip', true)
    ->orWhere(function ($query) {
        $query->where('created_at', '>', now()->subDay())
            ->where('trial', false);
    })
    ->get();

// whereBetween
DB::table('drinks')
    ->whereBetween('size', [6, 12])
    ->get();

// whereIn
DB::table('contacts')
    ->whereIn('state', ['FL', 'GA', 'AL'])
    ->get();

// whereNull / whereNotNull
DB::table('contacts')
    -> whereNull('nullable')
    -> get();
DB::table('contacts')
    -> whereNotNull('nullable')
    -> get();

// whereRaw, *beware of sql injection, queries passed to whereRaw will not be escaped
DB::table('contacts')->whereRaw('id = 12345')->get()

// whereExists
DB::table('users')
    ->whereExists(function ($query) {
        $query->select('id')
            ->from('comments')
            ->whereRaw('comments.user_id = users.id');
    })
    ->get();

// distinct
DB::table('contacts')->select('city')->distinct()->get();

modifying methods

// orderBy
DB::table('contacts')
    ->orderBy('last_name', 'asc')
    ->get();

// groupBy
DB::table('contacts')
    ->groupBy('city')
    ->havingRaw('count(contact_id) > 30')
    ->get();

// skip / take
DB::table('contacts')->skip(30)->take(10)->get();

// latest(colName = 'created_at') / oldest (colName = 'created_at')
DB::table('contacts')->latest()>get(); // order by descending created_at
DB::table('contacts')->oldest()>get(); // order by ascending created_at

// inRandomOrder
DB::table('contacts')->inRandomOrder()>get();

returning methods

xxx->get(); // all results
xxx->first(); // first result (LIMIT 1 added), first will fail if result is empty
xxx->firstOrFail() // throw exception if result is empty
xxx->find(5) // automatically get by ID. also can use findOrFail()
xxx->value('email') // get value from a single fields from the first row
xxx->count() // count of all of the matching results
xxx->min('col') // return min value of col
xxx->max('col') // return max value of col
xxx->dd() // dump the underlying SQL query

transaction

DB::transaction(function () use ($userId, $numVotes) {
    // Possibly failing DB query
    DB::table('users')
        ->where('id', $userId)
        ->update(['votes' => $numVotes]);

    // Caching query that we don't want to run if the above query fails
    DB::table('votes')
        ->where('user_id', $userId)
        ->delete();
});

manual transaction

DB::beginTransaction();
if ($badThingsHappened) {
    DB::rollBack();
}
DB::commit();

Databases and Eloquent ( Eloquent )

the simplest model definition
php artisan make:model Contact with migration php artisan make:model Contact --migration (-m)

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Contact extends Model
{
    use HasFactory;
}

customization

// The default behavior is like `SecondaryContact` should be `secondary_contacts`
protected $table = 'contacts_secondary';

// primary key, default is `id`
protected $primaryKey = 'contact_id';

// if need to disable autoincrement
public $incrementing = false;

// if don't need to add `careted_at` and `updated_at`
public $timestamps = false;

// date format customization ( default is probablly Datetime: Y-m-d H:i:s)
protected $dateFormat = 'U'; // Unix Timestamp

Handling Data with Eloquent

$allContacts = Contact::all();
$vipContacts = Contact::where('vip', true)->get();
$newestContacts = Contact::orderBy('created_at', 'desc') // or latest?
    ->take(10)
    ->get();
Contact::findOrFail($contactId)

chunk responses ( for memory usage or locking issue )

Contact::chunk(100, function ($contacts) {
    foreach ($contacts as $contact)  {
        // Do something with $contact
    }
});

aggregates

$countVips = Contact::where('vip', true)->count();
$sumVotes = Contact::sum('votes');
$averageSkill = User::avg('skill_level');

insert

$contact = new Contact;
$contact->name = 'Ken Hirata';
$contact->email = 'ken@hirata.com';
$contact->save();

// or

$contact = Contact::make([
    'name' => 'Ken Hirata',
    'email' => 'ken@hirata.com',
]);
$contact->save();

// or (immidiately save to database)
$contact = Contact::make([
    'name' => 'Ken Hirata',
    'email' => 'ken@hirata.com',
]);

update

$contact = Contact::find(1);
$contact->email = 'natalie@parkfamily.com';
$contact->save();

definition of fillable or guarded variables

class Contact
{
    protected $fillable = ['name', 'email'];

    // or

    protected $guarded = ['id', 'created_at', 'updated_at', 'owner_id'];
}

filtering variable from request

Contact::create($request->only('name', 'email'));

firstOrCreate

$contact = Contact::firstOrCreate(['email' => 'luis.ramos@myacme.com']);

Deletion

$contact = Contact::find(5);
$contact->delete();

or

Contact::destroy(1);
Contact::destroy([1, 5, 7]);
Contact::where('updated_at', '<', now()->subYear())->delete();

soft delete

// migration
Schema::table('contacts', function (Blueprint $table) {
    $table->softDeletes();
});

// model
<?php

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Contact extends Model
{
    use SoftDeletes; // use the trait

    protected $dates = ['deleted_at']; // mark this column as a date
}

// after that, delete() and destory() call will set the deleted_at

// retrieve not(?) soft deleted items
$allHistoricContacts = Contact::withTrashed()->get();

// retrieve soft deleted items
$deletedContacts = Contact::onlyTrashed()->get();

// to see whether instance has been soft-deleted or not
if ($contact->trashed()) {
    // do something
}

// restore item from soft-deleted state
$contact->restore();
Contact::onlyTrashed()->where('vip', true)->restore();

// force delete ( actually delete items from database )
$contact->forceDelete();
Contact::onlyTrashed()->forceDelete();
isopppisoppp

Databases and Eloquent ( Scope )

Add a local scope

class Contact
{
    public function scopeStatus($query, $status)
    {
        return $query->where('status', $status);
    }

use in query

$friends = Contact::status('friend')->get();

Add a global scope to a Model

class Contact extends Model
{
    protected static function boot()
    {
        parent::boot();

        static::addGlobalScope('active', function (Builder $builder) {
            $builder->where('active', true);
        });
    }

or create a global scope class

<?php

namespace App\Scopes;

use Illuminate\Database\Eloquent\Scope;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Builder;

class ActiveScope implements Scope
{
    public function apply(Builder $builder, Model $model)
    {
        return $builder->where('active', true);
    }
}

use in Model

<?php

use App\Scopes\ActiveScope;
use Illuminate\Database\Eloquent\Model;

class Contact extends Model
{
    protected static function boot()
    {
        parent::boot();

        static::addGlobalScope(new ActiveScope);
    }
}

remove global scopes in query

$allContacts = Contact::withoutGlobalScope('active')->get();
Contact::withoutGlobalScope(ActiveScope::class)->get();
Contact::withoutGlobalScopes()->get(); // disable all global scope
isopppisoppp

Databases and Eloquent ( Accessors / Mutators / Attribute Casting )

Accessors

The function name should be get{SampleName}Attribute

Handle empty attribute

// Model definition:
class Contact extends Model
{
    public function getNameAttribute($value)
    {
        return $value ?: '(No name provided)';
    }
}

// Accessor usage:
$name = $contact->name;

Define new a attribute which doesn't exist in the database

// Model definition:
class Contact extends Model
{
    public function getFullNameAttribute()
    {
        return $this->first_name . ' ' . $this->last_name;
    }
}

// Accessor usage:
$fullName = $contact->full_name;

Mutators

The mutator name should be set{SampleName}Attribute

// Defining the mutator
class Order extends Model
{
    public function setAmountAttribute($value)
    {
        $this->attributes['amount'] = $value > 0 ? $value : 0;
    }
}

// Using the mutator
$order->amount = '15';

proxy column, this is uncommon method because it can be confusing

// Defining the mutator
class Order extends Model
{
    public function setWorkgroupNameAttribute($workgroupName)
    {
        $this->attributes['email'] = "{$workgroupName}@ourcompany.com";
    }
}

// Using the mutator
$order->workgroup_name = 'jstott';

Attribute Casting

class Contact
{
    protected $casts = [
        'vip' => 'boolean',
        'children_names' => 'array',
        'birthday' => 'date',
    ];
}

Date Mutators

class Contact
{
    protected $dates = [
        'met_at',
        // already added created_at and updated_at by default
    ];
}
isopppisoppp

Databases and Eloquent ( Eloquent Serialization )

two types of serializer

$contactArray = Contact::first()->toArray();
$contactJson = Contact::first()->toJson();
$contactsArray = Contact::all()->toArray();
$contactsJson = Contact::all()->toJson();

The result of converting Eqloquent instance or string to string is the same as toJson
And every routes try to return result as string, so we can easily return Json response like

// routes/web.php
Route::get('api/contacts', function () {
    return Contact::all();
});

Route::get('api/contacts/{id}', function ($id) {
    return Contact::findOrFail($id);
});

Hiding attributes from json

class Contact extends Model
{
    public $hidden = ['password', 'remember_token'];
    // or 
    public $visible = ['name', 'email', 'status'];

Mannually change visibility

$array = $user->makeVisible('remember_token')->toArray();
isopppisoppp

Databases and Eloquent ( Eloquent Relationship )

One to One

// class def
class Contact extends Model
{
    public function phoneNumber()
    {
        return $this->hasOne(PhoneNumber::class);
        return $this->hasOne(PhoneNumber::class, 'owner_id'); // if you want to use 'owner_id’, not 'contact_id'
    }

// usage
$contact = Contact::first();
$contactPhone = $contact->phoneNumber;

// inverse
class PhoneNumber extends Model
{
    public function contact()
    {
        return $this->belongsTo(Contact::class);
    }

$contact = $phoneNumber->contact;

inserting related items

$contact = Contact::first();

$phoneNumber = new PhoneNumber;
$phoneNumber->number = 8008675309;
$contact->phoneNumbers()->save($phoneNumber);

// or

$contact->phoneNumbers()->saveMany([
    PhoneNumber::find(1),
    PhoneNumber::find(2),
]);

// or

$contact->phoneNumbers()->create([
    'number' => '+13138675309',
]);

// or

$contact->phoneNumbers()->createMany([
    ['number' => '+13138675309'],
    ['number' => '+15556060842'],
]);

One to Many

class User extends Model
{
    public function contacts()
    {
        return $this->hasMany(Contact::class);
    }

// usage
$user = User::first();
$usersContacts = $user->contacts;

// filtering
$donors = $user->contacts->filter(function ($contact) {
    return $contact->status == 'donor';
});

$lifetimeValue = $contact->orders->reduce(function ($carry, $order) {
    return $carry + $order->amount;
}, 0);

// inverse
class Contact extends Model
{
    public function user()
    {
        return $this->belongsTo(User::class);
    }
$userName = $contact->user->name;

attach and detach related item

$contact = Contact::first();

$contact->user()->associate(User::first());
$contact->save();

$contact->user()->dissociate();
$contact->save()

Selecting only records that have a related item

$postsWithComments = Post::has('comments')->get();
$postsWithManyComments = Post::has('comments', '>=', 5)->get();
$usersWithPhoneBooks = User::has('contacts.phoneNumbers')->get();

// Gets all contacts with a phone number containing the string "867-5309"
$jennyIGotYourNumber = Contact::whereHas('phoneNumbers', function ($query) {
    $query->where('number', 'like', '%867-5309%');
});

Has many through

class User extends Model
{
    public function phoneNumbers()
    {
        return $this->hasManyThrough(PhoneNumber::class, Contact::class);
    }

Has one through

class User extends Model
{
    public function phoneNumber()
    {
        return $this->hasOneThrough(PhoneNumber::class, Company::class);
    }

Many to Many

// pivot table should be contact_user

class User extends Model
{
    public function contacts()
    {
        return $this->belongsToMany(Contact::class);

        // or
        return $this->belongsToMany(Contact::class)
            ->withTimestamps()
            ->withPivot('status', 'preferred_greeting');
    }
}

class Contact extends Model
{
    public function users()
    {
        return $this->belongsToMany(User::class);
    }
}

Databases and Eloquent ( Eager Loading )

Eager Loading

$contacts = Contact::with('phoneNumbers')->get();
$contacts = Contact::with('phoneNumbers', 'addresses')->get(); // multiple
$authors = Author::with('posts.comments')->get(); // nested
$contacts = Contact::with(['addresses' => function ($query) {

Lazy eager loading

// lazy eager loading
$contacts = Contact::all();
