Question

当我使用laravel 5.4并在我的laravel文件夹中安装lavacharts时，现在我想从MySQL数据库中获取数据并且必须在DonutChart中显示相同的数据。

MyController.php

class ChartsController extends Controller
{
 function chart(){

    $lava = new Lavacharts; 
    $popularity = $lava->DataTable();

        $popularity2 = $lava->DataTable();


    $popularity ->addStringColumn('status')
                ->addNumberColumn('status')
                ->addRow(['Tickets Close', 5])
                ->addRow(['Tickets Open', 6])
                ->addRow(['Tickets Pending', 3]);


Lava::DonutChart('Popularity', $popularity, ['title'=>'Your Ticket Statistics'
    ]);


return view('chart',compact('lava'));

}

}

myView.blade.php

<div id="pop-div"></div>
<?= Lava::render('DonutChart', 'Popularity', 'pop-div') ?>

当我执行此代码时，我收到错误

ErrorException in Lavacharts.php line 129:
'DonutChart' is not a valid Lavachart object. (View: 
C:\wamp64\www\lavachart\resources\views\myView.blade.php

可以帮我解决这个问题吗？

我找到了答案。

我在视图中遇到的错误。我只是改变了我的看法

这是解决方案

这

@receiver(post_save, sender=EmailAddress)
def handle_email_address_save(sender, instance, created, update_fields, **kwargs):
    confirm = account_settings.ACCOUNT_EMAIL_CONFIRMATION_EMAIL
    must_confirm = instance.must_confirm if hasattr(instance, 'must_confirm') else False
    warning("handle_email_address_save called for email "
            + str(instance.email) + ", created = " + str(created)
            + ", confirm = " + str(confirm) + ", must_confirm = " + str(must_confirm))
    if confirm and not instance.verified and must_confirm:
        instance.send_confirmation()
        warning("handle_email_address_save sent confirmation")


# TODO: move to signals.py in quotes module
@receiver(comment_was_posted)
def handle_comment_posted(sender, comment, request, **kwargs):
    if comment.content_type.model == 'leadcontact':
       leadcontac = LeadContact.objects.get(pk=comment.object_pk)
       leadcontac.send_comment_posted_emails(comment)

要

<div id="pop-div"></div>
<?= Lava::render('DonutChart', 'Popularity', 'pop-div') ?>

'DonutChart'不是有效的Lavachart对象
