Save one to many without creating - laravel

Question

I just have a little problem. I have a one to many relationship. A team has many users. Many users have a team.
I have six teams of which the user has to choose one. How can I connect the team with the user without creating a new entry in the database 'team'?
User:
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id')->unique();
$table->string('name');
$table->integer('team_id')->unsigned()->nullable();
$table->foreign('team_id')->references('id')->on('users')->onDelete('cascade');
$table->string('username')->nullable()->unique();
$table->string('email')->unique();
$table->string('phone')->nullable()->unique();
$table->string('avatar');
$table->string('slug');
$table->string('password');
$table->date('birthday');
$table->boolean('gender');
$table->rememberToken();
$table->timestamps();
});
}
Team:
public function up()
{
Schema::create('teams', function (Blueprint $table) {
$table->increments('id')->unique();
$table->string('name');
$table->string('image');
$table->string('image_thumbnail');
$table->timestamps();
});
}
Controller:
public function storeTeam($request)
{
$user = Auth::user();
$team = Team::findOrFail($request->team_id);
$user->team()->associate($team);
return redirect()->back()->with('success', lang::get('messages.team'));
}
View:
<div class="col-md-12">
<form method="POST" action="{{ URL::route('store.team') }}">
{{ csrf_field() }}
<ul class="row clients-dotted list-inline text-center">
#foreach ($teams as $team)
<li class="col-md-4 col-sm-3 col-6">
<div class="cc-selector">
<input id="team{{$team->id}}" type="radio" name="team" value="{{$team->id}}" />
<label style="background-image:url({{ $team->image_thumbnail }});" class="team-cc" for="team{{$team->id}}"></label>
<p>{{$team->name}}</p>
</div>
</li>
#endforeach
</ul>
<button type="submit" class="mb-50 float-right mr-20 btn btn-shadow-1 btn-primary">weiter</button>
</form>
route:
Route::post('/welcome/team', 'ProfilesController#storeTeam')->name('store.team');
i have a little problem with this and get the error:
Type error:
Type error: Too few arguments to function App\Http\Controllers\ProfilesController::storeTeam(), 0 passed and exactly 1 expected

Assuming that you're storing the team_id on the user model, you can use the associate method to set the primary key on the child -- user in this case
$user->team()->associate($team);
You would pass the selected team to the controller. Doesn't matter how. You can pass it as part of a route, or you can pass the team ID from a form and get it from the request.
You're expecting a variable to literally be passed to the controller called $request. What you want is to inject $request as a dependency. You can do that by typehinting the resolved variable like so:
public function storeTeam(Request $request)
Mind you, you'll need to have use Illuminate\Http\Request; at the top of your file, otherwise you will get errors regarding the Request class.
