Laravel：如何使用外键插入数据

Question

I'm having trouble with the foreign key. I have two tables. users table and user_address table. I'll show you the migration.

users table:

public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('username')->unique()->nullable();
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

and this is the user_address table:

public function up()
    {
        Schema::create('user_address', function (Blueprint $table) {
            $table->id();
            $table->unsignedBigInteger('user_id');
            $table->integer('mobile_no')->nullable();
            $table->foreign('user_id')->references('id')->on('users')->onUpdate('cascade')->onDelete('cascade');
            $table->string('address')->nullable();
            $table->string('street')->nullable();
            $table->string('city')->nullable();
            $table->string('state')->nullable();
            $table->timestamps();
        });
    }

I don't know what to add or to insert in controllers / models / web routes. :( please help me out.

I have Models for users and user_address users model:

class User extends Authenticatable
{
    use HasFactory, Notifiable;
    protected $fillable = [
        'name',
        'username',
        'email',
        'password',
        'role_name',
    ];

    protected $hidden = [
        'password',
        'remember_token',
    ];

    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function setUsernameAttribute($value) {
        if ( empty($value) ) {
        $this->attributes['username'] = NULL;
        } else {
            $this->attributes['username'] = $value;
        }
    }

and the user_address table:

class User_Address extends Model
{
    use HasFactory;

    protected $fillable = [
        'mobile_no',
        'shipping_address',
        'barangay',
        'city',
        'province',
    ];
}

Answer 1

Maybe try something like that:

$user_post=request()->get('name','username','email');
$address_post=request()->get('street','city','address')

$user = new User();
$user -> fill($user_post];
$user->save();


$id=$user->id;

$address_post['user_id']=$id;
$address = new UserAdress();
$address -> fill($user_address);
$address -> save();

I don't remember now if it should be fill() or insert().

Answer 2

I would suggest creating a relationship in the User model to start with

public function address() {
    return $this->hasOne(Addres::class, 'user_id);
}

you can probably get away by doing

tap(
   User::create(request()->get('name','username','email')), 
   fn($user)=> $user->address()
             ->save(request()->get('street','city','address')
)

Or without relationship, you will have to do something like

tap(
   User::create(request()->get('name','username','email')), 
   fn($user)=> Address::create[array_merge(
             ['user_id' => $user->id], 
             request()->get('street','city','address')
           )
