Laravel雄辩的分页不存在错误

Question

我正在尝试在Laravel刀片/视图中设置分页，但以下消息显示错误：

BadMethodCallException

方法Illuminate \\ Database \\ Eloquent \\ Collection :: paginate不存在。

调节器

public function view()
{
    $user = Auth::user();
    $basic_info = User::find($user->id)->basic_info;
    $category = Category::all()->paginate(10); 

    return view('admin.article.category-view')->with(['user' => $user, 'basic_info' => $basic_info, 'category' => $category]);
}

查看刀片 （admin.article.category-view）

<div class="panel-body">
    <table class="table table-hover">
        <thead>
        <tr>
            <th>Category Name</th>
        </tr>
        </thead>
        <tbody>
        @foreach($category as $cat)
            <tr>
                <td>{{ $cat->name }}</td>
            </tr>
        @endforeach
        </tbody>
    </table>
    {{ $category->links() }}
</div>

Answer 1

仅在查询生成器或Eloquent查询（而不是集合）上使用paginate方法，如下所示：

public function view()
{
    $user = Auth::user();
    $basic_info = User::find($user->id)->basic_info;
    $category = Category::paginate(10); 

    return view('admin.article.category-view')->with(['user' => $user, 'basic_info' => $basic_info, 'category' => $category]);
}

Answer 2

您需要删除all() ：

 $category = Category::paginate(10); 

当您使用all()您将从表中获取所有行并获取一个集合

您只能在Query上调用"paginate" ，而不能在Collection上调用。
