Получить все данные из сводной таблицы

Question

Теперь я могу получить данные в сводной таблице, но мой вопрос: как я могу получить все категории из таблицы категорий и, если существует эта категория в моей сводной таблице, вход нужно проверить, как я могу это получить?

модель проекта

class Project extends Model 
{ 
    protected $table = 'projects'; 

    protected $fillable = [ 
     'name', 
     'slug', 
     'header', 
     'desc', 
     'about', 
     'url', 
     'status' 
    ]; 

    public function customer() 
    { 
     return $this->belongsTo(Customer::class); 
    } 

    public function category() 
    { 
     return $this->belongsToMany(Category::class)->withPivot('category_id'); 
    } 
} 

Категория модель

class Category extends Model 
{ 
    protected $table = 'categories'; 

    protected $fillable = [ 
     'name', 
     'status' 
    ]; 

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

    public function subCategory() 
    { 
     return $this->hasMany(SubCategory::class); 
    } 

    public function projects() 
    { 
     return $this->belongsToMany(Project::class)->withPivot('project_id'); 
    } 
} 

Контроллер

public function getEdit(Customer $customer, $project) 
{ 
    return view('admin.pages.admin.clientes.projetos.edit', [ 
     'customer' => $customer, 
     'project' => Project::where('id', $project)->firstOrFail(), 
     'categories' => $this->categoryRepository->allCategories(), //return all categories in the categories table 
     'title' => $customer->name 
    ]); 
} 

Форма

{!! Form::model($project, ['class' => 's-form', 'route' => ['project.update', $customer->id, $project->id]]) !!} 
    {{ method_field('PUT') }} 
    <div class="s-form-item text">

     <div class="item-title">Categorias do projeto</div> 
     @foreach($project->category as $category) 
      {{-- Here I get all the categories, and the categories that exists in the pivot table will be checked--}} 
      {{--<div class="s-checkbox s-radio-input">--}} 
       {{--<input id="category-{{ str_slug($category->name) }}" type="checkbox" name="categories[]" value="{{ $category->id }}">--}}

В контроллере необходимо выбрать проект с его категориями:

public function getEdit(Customer $customer, $project) 
{ 
    return view('admin.pages.admin.clientes.projetos.edit', [ 
     'customer' => $customer, 
     'project' => Project::with('category')->findOrFail($project), 
     'categories' => $this->categoryRepository->allCategories(), //return all categories in the categories table 
     'title' => $customer->name 
    ]); 
} 

Затем в HTML:

<div class="s-form-item checkbox inline"> 
    <div class="item-title">Categorias do projeto</div> 
    @foreach($categories as $category) 
     <div class="s-checkbox s-radio-input"> 
      <input id="category-{{ str_slug($category->name) }}" type="checkbox" name="categories[]" {{$project->category->contains($category) ? 'checked="true"' : ''}} value="{{ $category->id }}"> 
      <label for="category-{{ str_slug($category->name) }}"><span></span>{{ $category->name }}</label> 
     </div> 
    @endforeach 
</div> 

обновить проект с выбранными категориями:

$project = Project::findOrFail($project); 
$project->category()->sync($request->input('categories', [])); 
$project->update($request->except(['_token','_method', 'categories']); 

I Надеюсь, что это поможет вам.
