Question

我花了很长时间才开始这样做，它只是不起作用，所以我放弃了，而是用Fluent更新方法重写它。

但我想在此发布，看看是否还有其他人遇到过这个问题。

// TEST CONTROLLER
$user = User::find(29);
// This user has a related subscription but it's lacking all of the braintree data that I need 
// So as a fallback I need to make sure that if the braintree_customer_id column is empty
// then we query braintree with an email lookup for the customer
// and then fill in the missing data.

$data = $user->subscription->braintree_customer;
var_dump($data);

// SUBSCRIPTION MODEL
public function get_braintree_customer()
{
    $braintree_customer_id = $this->braintree_customer_id;
    if (empty($braintree_customer_id))
    {
        // IF THE CUSTOMER DOESN"T HAVE ID SET THEN CALL ANOTHER FUNCTION IN THE MODEL
        $data = $this->customer_from_braintree;
        return $data;
    }
    $data = Braintree_Customer::find($braintree_customer_id);
    return $data;
}
public function get_customer_from_braintree()
{
    $data = FALSE;
    $braintree_customer = Braintree_Customer::search(array(
        Braintree_CustomerSearch::email()->is($this->user->email),
        // Braintree_CustomerSearch::email()->is('bleugh@pixelapes.com'),
    ));
    if (!empty($braintree_customer->_ids))
    {
        $braintree_customer_id = $braintree_customer->_ids[0];
        $data = Braintree_Customer::find($braintree_customer_id);
        $braintree_subscription = $data->creditCards[0]->subscriptions[0];

            $this->braintree_customer_id = $data->id;
            $this->braintree_subscription_id = $braintree_subscription->id;
            $this->braintree_payment_method_token = $braintree_subscription->paymentMethodToken;
            $this->braintree_plan_id = $braintree_subscription->planId;
            $this->save();
    }
    return $data;
}}
// IF I TRY USING $this->save() I get this error
// Even though I haven't tried to create a new Subscription - just update the old one

我已经尝试了我能想到的每一个Eloquent更新方法，我尝试在第二个模型函数中直接使用set_attribute（）函数，我尝试为每个要更新的列创建setter并调用那些setter，但随后函数成功但行未更新。

但是，如果我尝试在测试控制器中手动运行setter，它们可以正常运行吗？！

我尝试直接从控制器调用模型函数，但仍然会导致错误。

最奇怪的是，在我的用户模型中，我已经完成了这个精确的方法，然后我在$ this上设置属性，然后运行$ this-＆gt; save（）;它工作正常。

莫名其妙！

Answer 1

根据David Barker的评论 - 我覆盖了__construct（）

我必须从父类中提取$ attributes和$ exists。

现在可以使用了。

public function __construct($attributes = array(), $exists = false) {
    parent::__construct($attributes, $exists); // initialize the model according to the parent class functionality.
    require_once path('app').'libraries/braintree_php/lib/Braintree.php';
    Braintree_Configuration::environment(Config::get('braintree.environment'));
    Braintree_Configuration::merchantId(Config::get('braintree.merchant_id'));
    Braintree_Configuration::publicKey(Config::get('braintree.public_key'));
    Braintree_Configuration::privateKey(Config::get('braintree.private_key'));
}
