Blade 在尝试显示 Json 数据时返回“1”

Question

我正在尝试在刀片中显示 json 结果，但是当我尝试显示州名，地区名称时，从对应关系中，我在刀片中得到 1， 我能够显示“用户”关系和“新安装”。

我的模特

NewInstallation.php

public function newInstallationPrePayment()
{
    return $this->hasMany(NewInstallationPrePayment::class, 'installation_order_id', 'id');
}

public function state()
{
    return $this->hasOne(State::class, 'id', 'state');
}

public function district()
{
    return $this->hasOne(District::class, 'id', 'district');
}

NewInstallationPaymentStatus.php

public function newInstallationPrePayment()
{
    return $this->belongsTo(NewInstallationPrePayment::class, 'order_name', 'order_name');
}

控制器

$new_installation_order = NewInstallationPaymentStatus::with([
        'newInstallationPrePayment.newInstallation.state',
        'newInstallationPrePayment.newInstallation.district',
        'newInstallationPrePayment.newInstallation.user']
    )->findOrFail($id);

刀片

{{$new_installation_order}} 

我得到低于上述的 json 结果

但是当我尝试调用 state 时

{{$new_installation_order['newInstallationPrePayment']['newInstallation']['district'] }}

当我使用这个时，我得到 1

Json：

Answer 1

如果您将数据编码为 json 然后发送到视图，我不会。它似乎是一个 json 对象，而不是 php 数组。这就是为什么刀片不能迭代它。如果您将其编码为 json，请尽量不要这样做。或者尝试在将其发送到视图之前对其进行解码。

return view('viewname')->with(['new_installation_order' => json_decode($new_installation_order)])

那就试试这个

{{$new_installation_order->newInstallationPrePayment->newInstallation->district }}

您还可以解码刀片文件中的 json。做最适合你的事情。

Answer 2

您可能想尝试将特定参数而不是整个对象传递给您的视图。我怀疑这是因为您将 json 作为字符串传递给视图。

所以试试这样吧：

$district = $new_installation_order['newInstallationPrePayment']['newInstallation']['district'];

return view('test')->with(['district' => $district]);

您能否发布在您的控制器上调用的整个方法，或者至少发布 return 语句？
