Question

为什么我不能生成来自数据库的数据？我可以渲染图表，但没有显示数据。但是，当我转储数据时，它向我显示了数据数组。帮助将不胜感激。谢谢。图表输出就在这里：https://imgur.com/a/eyCVxSn

PS：我想在第二个数据库中获取数据。这就是为什么模型中有“ mysql2”的原因。

GraphController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
use Illuminate\Support\Facades\DB;
use View;
use App\News;
use Charts;
use App\Graph;

class GraphController extends Controller
{
    /**
    * Display a listing of the resource.
    *
    * @return \Illuminate\Http\Response
    */
    public function index()
    {



        $graph = Charts::database(Graph::find(1),'line','highcharts')
        ->title('Tokens')
        ->ElementLabel('Coins Sold')
        ->Responsive(true)
        ->dimensions(1000,500)
        ->data(Graph::find(1));

        dd($graph);

        $news = News::all();


        // //dd($news);
        return View::make('coin.news', compact('graph','news'));
    }
}

Graph.php模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Auth;
use Cache;
use Charts;


class Graph extends Model
{
    //

    protected $connection = 'mysql2';
    protected $table = 'ico_stages';



}

graph.blade.php




@section('graph')



        {!! $graph->render() !!}



@endsection

app.blade.php

stylesheets....

{!! Charts::assets() !!}

@yield('graph')

news...

scripts...

当我使用dd（$ graph）时，它显示了这一点。我还可以在图表中看到要渲染的数据。

在图形模板中呈现数据

$graph = view('graph')->with('graph', $graph);

并将渲染的数据返回新闻

return view('coin.news', compact('graph','news'));

最终密码

    $graph = Charts::database(Graph::find(1),'line','highcharts')
    ->title('Tokens')
    ->ElementLabel('Coins Sold')
    ->Responsive(true)
    ->dimensions(1000,500)
    ->data(Graph::find(1));



    $news = News::all();

    $graph = view('graph')->with('graph', $graph); 

    return view('coin.news', compact('graph','news'));
