我正在尝试在我的应用程序中实现 TBBC Money/Currency Bundle，但它不起作用。我认为问题来自我的控制器和树枝文件。我对这个捆绑包的文档有点迷茫。
任何帮助，将不胜感激！
这是我的 config.yml
tbbc_money:
currencies: ["USD", "EUR"]
reference_currency: "EUR"
decimals: 2
enable_pair_history: true
ratio_provider: tbbc_money.ratio_provider.google
twig:
debug: "%kernel.debug%"
strict_variables: "%kernel.debug%"
form:
resources:
- 'TbbcMoneyBundle:Form:fields.html.twig'
post.php
/**
* @var integer
*
* @ORM\Column(name="price_amount", type="integer")
*/
private $priceAmount;
/**
* @var string
*
* @ORM\Column(name="price_currency", type="string", length=64)
*/
private $priceCurrency;
/**
* get Money
*
* @return Money
*/
public function getPrice()
{
if (!$this->priceCurrency) {
return null;
}
if (!$this->priceAmount) {
return new Money(0, new Currency($this->priceCurrency));
}
return new Money($this->priceAmount, new Currency($this->priceCurrency));
}
/**
* Set price
*
* @param Money $price
* @return Post
*/
public function setPrice(Money $price)
{
$this->priceAmount = $price->getAmount();
$this->priceCurrency = $price->getCurrency()->getName();
return $this;
}
PostType.php
->add('price', 'tbbc_money')
新的.html.twig
（我确定这部分代码是错误的，我必须用其他东西替换它？？）
<div class="form-group form-group-lg form-group-icon-left">
<i class="fa fa-plane input-icon"></i>
<label>price</label>
{{ form_widget(form.price, { 'attr': {'class': 'form-control',} }) }}
{{ form_errors(form.price) }}
</div>
后控制器.php
（我不知道我应该在控制器中放什么。）

编辑：
我确实在我的控制器中有这个：
public function myAction()
{
$moneyFormatter = $this->get('tbbc_money.formatter.money_formatter');
$price = new Money(123456789, new Currency('EUR'));
// best method (added in 2.2+ version)
\Locale::setDefault('fr_FR');
$formatedPrice = $moneyFormatter->localizedFormatMoney($price);
// 1 234 567,89 €
$formatedPrice = $moneyFormatter->localizedFormatMoney($price, 'en');
// €1,234,567.89
// old method (before v2.2)
$formattedPrice = $moneyFormatter->formatMoney($price);
// 1 234 567,89
$formattedCurrency = $moneyFormatter->formatCurrency($price);
// €
}
然后我得到了这个错误：
在 src\FLY\BookingsBundle\Resources\views\Post\show.html.twig 中的模板（“可捕获的致命错误：Money\Money 类的对象无法转换为字符串”）的呈现过程中引发异常第 30 行。
这是我在 show.html.twig 中的第 30 行
<span class="price"><small>Price</small>${{ entity.price }}</span>
