在结帐页面上,我需要在验证VAT字段(验证在控制器中完成)之后更新订单总计并从总计中删除VAT。价格也需要保存在后端的订单视图中。
我已经尝试通过自定义js进行更新,并且在前端工作正常,但是无法保存在后端的订单视图中
define([
'jquery',
'Magento_Checkout/js/model/quote',
'Magento_Checkout/js/model/resource-url-manager',
'mage/storage',
'Magento_Checkout/js/action/get-payment-information',
'Magento_Checkout/js/model/totals',
'Magento_Checkout/js/model/full-screen-loader',
'Magento_Checkout/js/action/get-totals',
'Magento_Checkout/js/model/cart/totals-processor/default'
], function ($, quote, urlManager,storage, getPaymentInformationAction, totals, fullscreenLoader,
getTotalsAction) {
'use strict';
return function (removeTax, tax) {
var payload = {
addressInformation: {
shipping_address: quote.shippingAddress(),
billing_address: quote.billingAddress(),
shipping_method_code: quote.shippingMethod().method_code,
shipping_carrier_code: quote.shippingMethod().carrier_code
}
};
fullscreenLoader.startLoader();
return storage.post(
urlManager.getUrlForSetShippingInformation(quote),
JSON.stringify(payload)
).done(function (response) {
if(removeTax) {
response.totals.total_segments[2].value = -tax;
response.totals.total_segments[4].value -= tax;
} else {
response.totals.total_segments[2].value = tax;
response.totals.total_segments[4].value += tax;
}
var deferred = $.Deferred();
totals.isLoading(true);
getTotalsAction([], deferred);
$.when(deferred).done(function () {
quote.setTotals(response.totals);
totals.isLoading(false);
fullscreenLoader.stopLoader();
});
}).fail(function (response) {
console.log('fail');
totals.isLoading(false);
fullScreenLoader.stopLoader();
});
};
});
另一方面,我也尝试通过etc / sales.xml更改订单总数。在这里,我成功地在前端视图和管理订单视图上进行了更新,但是仅在验证了VAT字段之后,我才能设法进行这些调整。这是我的模型收集功能:
public function collect(
\Magento\Quote\Model\Quote $quote,
\Magento\Quote\Api\Data\ShippingAssignmentInterface $shippingAssignment,
\Magento\Quote\Model\Quote\Address\Total $total
) {
parent::collect($quote, $shippingAssignment, $total);
$currentTax = $total->getTaxAmount();
$total->setTaxAmount(-$currentTax);
$total->setBaseTaxAmount(-$currentTax);
$total->setGrandTotal($total->getGrandTotal() - $currentTax);
$total->setBaseGrandTotal($total->getBaseGrandTotal() - $currentTax);
return $this;
}
因此,我尝试设置如下会话消息:$ this-> session-> setMySession(“ Valid VAT”);在我要验证增值税的控制器中,然后仅在以下情况下在模型中进行更改:
if($this->session->getMySession() == "Valid VAT" ){
.........
}
但是它没有设置会话消息,因为模型是在第一次加载页面时加载一次,并且在验证之后我无法重新加载它。
只有在控制器中进行验证之后,任何人都可以帮助或指导我如何更改价格吗?
预先感谢
