拉拉维尔 5.7
您好,我一直在查看堆栈溢出,并尝试了许多可能的答案,但没有得出任何结论。
我正在通过简单的检查更新赞助人表中的简单整数值,它没有更新数据库。我已经尝试在模型上使用save()和update()方法。
没有出现错误或异常,save()andupdate()方法返回true。
代码:
控制器类使用模型和更新数据:
$patron_coupon = PatronCoupons::where('owner',$patron_id)->where('coupon_id',$active_coupon['coupon_id'])->first();
if($patron_coupon->current_uses > $active_coupon['max_uses'])
$patron_coupon->current_uses = $active_coupon['max_uses'];
// if i echo $patron_coupon->current_uses here, it will show that this value has changed ( good )
$patron_coupon->current_uses = $active_coupon['max_uses'] - $patron_coupon->times_used;
if($patron_coupon->current_uses < 0)
$patron_coupon->current_uses = 0;
// this doesnt work
$patron_coupon->save();
// this doesnt work either
$patron_coupon->update($patron_coupon->toArray());
// if i echo current_uses here, the value goes back to what it was before being set.
型号类:
class PatronCoupons extends Model
{
protected $table = 'patron_coupons';
protected $primaryKey = 'owner';
public $timestamps = false;
protected $fillable = ['times_used','current_uses','settings_version'];
}
迁移文件:
Schema::create('patron_coupons', function (Blueprint $table) {
$table->string('owner'); // patron id that 'owns' this coupon
$table->unsignedInteger('coupon_id'); // id of this coupon
$table->unsignedInteger('current_uses')->default(0); // the amount of uses this patron has for this coupon
$table->unsignedInteger('settings_version')->nullable();// last settings version fetch
$table->unsignedInteger('times_used')->default(0); // amount of times this coupon has been used
});
请帮忙,我已经在桌子上撞了几个小时了!!!!!!!
