Слишком мало аргументов для функции Illuminate \ Database \ Eloquent \ Relations \ HasOneOrMany :: save

Question

Посмотри мои коды, я хочу сохранить информацию, потом все разваливается.

У меня три таблицы, houses & categories & category_house.

домов & category_house таблицы

public function up()
{
    Schema::create('houses', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->bigInteger('user_id')->unsigned();
        $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
        $table->string('title');
        $table->string('slug');
        $table->string('lang');
        $table->string('image')->nullable();
        $table->text('sliders');
        $table->text('body');
        $table->timestamps();
    });
    Schema::create('category_house', function (Blueprint $table) {
        $table->bigInteger('category_id')->unsigned();
        $table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
        $table->bigInteger('house_id')->unsigned();
        $table->foreign('house_id')->references('id')->on('houses')->onDelete('cascade');
        $table->primary(['category_id' , 'house_id']);
    });
}

таблица категорий

public function up()
{
    Schema::create('categories', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name');
        $table->string('lang');
        $table->string('href')->nullable();
        $table->integer('parent_id');
        $table->string('icon')->nullable();
        $table->timestamps();
    });
}

edit.blade. php

<form action="{{ route('houses.update', $house->id) }}" method="post">
    @csrf
    @method('PUT')
    <input type="hidden" name="sliders">
    <div class="col-md-6">
        <div class="form-group">
            <label for="title">Title</label>
            <input type="text" class="form-control" id="title" name="title" value="{{ old('title') ?? $house->title }}">
        </div>
    </div>
    <div class="col-md-12">
        <div class="form-group">
            <label for="body">Body</label>
            <textarea class="form-control" id="body" name="body">{{ old('body') ?? $house->body }}</textarea>
        </div>
    </div>
    <div class="col-md-6">
        <div class="form-group">
            <label for="category">Sub Category</label>
            <select name="category" id="category" class="form-control">
                @foreach($categories as $category)
                    <option value="{{ $category->id }}" {{ $house->categories()->pluck('id')->contains($category->id) ? 'selected' : '' }}>
                        {{ $category->name }}
                    </option>
                @endforeach
            </select>
        </div>
    </div>
    <div class="col-md-6">
        <div class="form-group">
            <label for="lang">Language</label>
            <select id="lang" name="lang" class="form-control">
                <option value="fa" {{ $house->lang == 'fa' ? 'selected' : '' }}>Farsi</option>
                <option value="en" {{ $house->lang == 'en' ? 'selected' : '' }}>English</option>
            </select>
        </div>
    </div>
    //.....
    <div class="form-group">
        <button class="btn btn-primary btn-lg btn-block">
            <i class="fas fa-check ml-2"></i>Save
        </button>
    </div>
</form>

HouseController. php

 public function update(Request $request, House $house)
{
    $house->user_id = 1;
    $house->title = $request->title;
    $house->lang = $request->lang;
    $house->body = $request->body;
    if($request->has('image')) {
        $image = $request->file('image');
        $filename = $image->getClientOriginalName();
        $image->move(public_path('images/slideShows'), $filename);
        $house->image = $request->file('image')->getClientOriginalName();
    }
    $house->save();
    $house->categories()->sync($request->category);
    $category = Category::findOrFail($request->get('category'))->getParent();
    $category->name = $request->title;
    $category->parent_id = $request->category;
    $category->lang = $request->lang;
    $category->href = $request->slug;
    $category->save();
    return redirect()->route('houses.index');
}

Категория. php

public function getParent ()
{
    return $this->hasOne(Category::class, 'id', 'parent_id')->withDefault(['name' => '-']);
}

Например, у меня в базе данных есть следующие категории:

id ---- name ------ ----------- lang ------ href --------- parent_id -------- icon ---- ------------- created_at -------- updated_at 8 ----- Main Menu -------- en - --------- NULL ------ 0 --------------------- fas fa-cube ----- - NULL ---------------- NULL

Правильный метод должен быть сохранен здесь

id ---- name ----------------- lang ------ href ------------------ ---- parent_id -------- icon ----------------- created_at -------- updated_at 8 ----- Main Menu -------- en ---------- NULL ---------------- --- 0 --------------------- fas fa-cube ------ NULL ----------- ----- NULL * 1 061 * --- Duplex House ---- en ---------- duplex-house ------ 8 ------------- -------- NULL --------------- NULL ---------------- NULL

Но так сохраняется.

id ---- name ----------------- lang --- --- href ---------------------- parent_id -------- icon -------- --------- created_at -------- updated_at 8 ----- Duplex House ---- en --------- NULL ------------------- 8 --------------------- fas fa-cube - ----- NULL ---------------- NULL 20 --- Duplex House ---- en ------- - NULL ------------------- 8 --------------------- NULL --------------- NULL ---------------- NULL

И когда я изменил этот код

$category = Category::findOrFail($request->get('category'))->getParent();

Я получаю эту ошибку
