如何将 Laravel 数据表（yajra）添加到现有项目中？

Question

是否有任何可能的方式将 yajra 数据表添加到现有项目？ 如果我将它实现到空白 view.blade.php 效果很好，但如果我把它放到我现有的项目中，它只会显示广告。

我的控制器：

 namespace App\Http\Controllers;

use App\Models\User;
use Illuminate\Http\Request;
use Yajra\DataTables\DataTables;


class UserRecordController extends Controller
{
    public function __construct()
    {
        $this->middleware(['role:admin']);
    }

    public function show()
    {
        $data = User::all()->all();

        return view('management.admin-only.users.users_record')->with('data', $data);
    }

    public function index(Request $request)
    {
        if ($request->ajax()) {
            $data = User::all()->all();
            return Datatables::of($data)
                ->addIndexColumn()
                ->addColumn('action', function($row){

                    $btn = '<a href="javascript:void(0)" class="edit btn btn-primary btn-sm">View</a>';

                    return $btn;
                })
                ->rawColumns(['action'])
                ->make(true);
        }

        return view('management.admin-only.users.users_record');
    }
}

我的看法：

@extends('layouts.app')

@section('content')
    <div class="row admin-panel">
        @include('management.common.admin_sidebar')
        <div class="col" id="main">
            <div class="card panel-stats">
                <div class="card-body">
                    <div class="flash-message">
                        @foreach (['danger', 'warning', 'success', 'info'] as $msg)
                            @if(Session::has('alert-' . $msg))
                                <p class="alert alert-{{ $msg }}">{{ Session::get('alert-' . $msg) }} <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a></p>
                            @endif
                        @endforeach
                    </div>
                    <div class="card-title">
                        <div class="card-body">
                            <div class="card-body">
                                <h2><img class="py-2 mr-3" height="100px" width="auto" src="{{ asset('img/admin/group.jpg') }}">Users</h2>
                            </div>

                            <a href="{{Route('users_add')}}" class="btn btn-outline-success">Add user</a>

                            <a href="" id="user-edit" onclick="" class="btn btn-outline-primary" data-toggle="tooltip" data-placement="top" title="Choose 1 user to edit">Edit user</a>
                            <a href="" id="user-delete" onclick="return confirmation()" class="btn btn-outline-danger" data-toggle="tooltip" data-placement="top" title="Choose 1 user to delete">Delete user</a>


                        </div>
                        <div class="card-body">
                                <div class="card">

我的路线：

Route::get('/admin_panel/users_record','UserRecordController@index')->name('users_record');

我使用了多个教程 - 每个看起来都相似。我刚刚将所有必要的 webpack 导入 app.blade.php。

我做错了什么？

Answer 1

你需要两个功能，一个是用于加载视图

public function index(){
return view('management.admin-only.users.users_record');
}

和另一个获取数据的函数

public function get_users_record(Request $request){
 if ($request->ajax()) {
        $data = User::all()->all();
        return Datatables::of($data)
            ->addIndexColumn()
            ->addColumn('action', function($row){

                $btn = '<a href="javascript:void(0)" class="edit btn btn-primary btn-sm">View</a>';

                return $btn;
            })
            ->rawColumns(['action'])
            ->make(true);
    }
}

路线将是

Route::get('/admin_panel/users_record','UserRecordController@index')->name('users_record');
    Route::get('/admin_panel/get_users_record','UserRecordController@get_users_record')->name('get_users_record');

和ajax url应该是

 ajax: "{{ route('get_users_record') }}",
