I am beginner of laravel, I want to store a book to books database, but after click button, it shows "Method Illuminate\Database\Eloquent\Collection::books does not exist." What am I missing?
here are my codes.

**BookController**

```
public function create()
{
    return view('books.create');
}

public function store(Request $request)
{
    $this->validate($request, [
        'book' => 'required|max:255',
        'category' => 'required',
        'quantity' => 'required|numeric',
        'price'=>'required|numeric',
        'info'=>'required'
    ]);
    //$request->user()->member()->books()->create([
    $member=auth()->user()->member()->get();
    $member->books()->create([
        'book' => $request->book,
        'category' => $request->category,
        'quantity' => $request->quantity,
        'price'=>$request->price,
        'info'=>$request->info
    ]);

    return redirect('shops')->with('success', 'successful');
}

```

**books.create**

```
<form action="{{route('books.store')}}" method="POST" role="form">

        @csrf
        @method('POST')
        <div class="form-group">
            <label for="book">name：</label>
            <input id="book" name="book" class="form-control" placeholder="enter book name">
        </div>
        <div class="form-group">
            <label for="category">category：</label>
            <input id="category" name="category" class="form-control" placeholder="enter category">
        </div>
        <div class="form-group">
            <label for="quantity">quantity：</label>
            <input id="quantity" name="quantity" class="form-control" placeholder="enter quantity">
        </div>
        <div class="form-group">
            <label for="price">price：</label>
            <input id="price" name="price" class="form-control" placeholder="enter price">
        </div>
        <div class="form-group">
            <label for="info">info：</label>
            <textarea id="info" name="info" class="form-control" rows="10" placeholder="enter info"></textarea>
        </div>
        <button type="submit" class="btn-sm btn-primary">create</button>
    </form>

```

User and Member is one to one relation, and Book belongs to one Member

**Book Model**

```
public function member()
{
    return $this->belongsTo(Member::class);
}
protected $fillable = ['book','category','quantity','price','info'];

```

**Member Model**

```
public function books()
{
    return $this->hasMany(Book::class);
}

public function user()
{
    return $this->belongsTo(User::class);
}

```

**User Model**

```
 public function member()
{
    return $this->hasOne(Member::class);
}

```

```
public function up()
{
    Schema::create('books', function (Blueprint $table) {
        $table->increments('id');
        $table->unsignedInteger('member_id');
        $table->foreign('member_id')->references('id')->on('members')->onDelete('cascade');
        $table->string('name');
        $table->integer('quantity');
        $table->integer('price');
        $table->string('path');
        $table->string('info');
        $table->string('category');
        $table->timestamps();
    });
}

```

**member migration**

```
public function up()
{
    Schema::create('members', function (Blueprint $table) {
        $table->increments('id');
        $table->unsignedbigInteger('user_id');
        $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
        $table->string('sex');
        $table->string('email');
