laravel 5.4 - blade; Function name must be a string, -

i new laravel , using 5.4, php 7.0

i have 3 tables: users, roles; profiles. able write each tables fine, when trying read profile table using blade, getting error: "function name must string"

in blade, have following code

@foreach(auth()->user()->profiles $profile)      profile id is: {{ $profile()->id }} !<br> - @endforeach  @foreach(auth()->user()->roles $role) role is: {{ $role->name }} !<br> @endforeach   

* first 1 gives error, second works fine *

* if put ( ) profiles *

@foreach(auth()->user()->profiles() $profile)      profile id is: {{ $profile()->id }} !<br> - @endforeach 

* not give error why ? *

i using 2 pivot table: 'role_users'

{ schema::create('role_users', function (blueprint $table) { $table->unsignedinteger('user_id'); $table->unsignedinteger('role_id'); $table->timestamps(); $table->unique(['user_id','role_id']);  $table->foreign('user_id')->references('id')->on('users')->ondelete('cascade')    ;  $table->foreign('role_id')->references('id')->on('roles')->ondelete('cascade') ;});  

second one: 'profiles_users'

schema::create('profiles_users', function (blueprint $table) { $table->increments('id'); $table->unsignedinteger('user_id'); $table->unsignedinteger('profile_id'); $table->timestamps(); $table->unique(['user_id','profile_id']); $table->foreign('user_id')->references('id')->on('users')->ondelete('cascade') ; $table->foreign('profile_id')->references('id')->on('profiles')->ondelete('cascade'); 

* in users model * both tables link following way:

public function profiles() { return $this->belongstomany(profile::class, 'profiles_users'); } public function roles() { return $this->belongstomany(role::class, 'role_users'); } 

* in profile model * user table link following way:

public function users() { return $this->belongsto(user::class,'profiles_users'); } 

* register controller has create function, end of function, make attach *

$user->roles()->attach($data['role']); // key link role_users table; works $user->profiles()->attach($profile['id']); // key link role_users table 

to write data table, attach works fine. * there wrong, when try read data profile table ? *

protected function create(array $data) { $user = user::create([ 'username' => $data['username'],   //  'email' => $data['email'], 'password' => bcrypt($data['password']), ]);  $profile = profile::create([          // works sava profile information  'firstname' => $data['firstname'], 'lastname' => $data['lastname'], 'nickname' => $data['nickname'], 'middlename' => $data['middlename'], ]);  $user->roles()->attach($data['role']); // key link role_users table; works $user->profiles()->attach($profile['id']); // key link role_users table return $user; return $profile;
