排序算法:Magento结帐总额未正确排序，导致错误的运费计算 [英] Sort algorithm: Magento checkout totals sorted wrongly causing wrong shipping tax calculation
本文介绍了排序算法:Magento结帐总额未正确排序，导致错误的运费计算的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
Magento中提供了一项功能，您可以通过指定总计之前和之后的总计次数来定义总计计算的顺序.
In Magento there is a functionality where you can define the order of total calculation by specifing before and after which totals a total should be run.
我添加了一个自定义总计，如果我在config.xml中添加以下行，则排序是错误的.错误的意思是:tax_shipping在之前 shipping.
这将导致运费税增加两次.
I added a custom total and if I add the following lines to the config.xml, the sorting is wrong. Wrong means: tax_shipping comes before shipping.
This causes the tax for the shipping cost to be added twice.
但这违反了条件
tax_shipping
after: shipping
我的猜测:整套规则中一定有一些矛盾之处.但是我怎么找到它呢?
My guess: There must be some contradiction in the full set of rules. But how can I find it?
这是我添加的唯一规则.没有此规则，tax_shipping将排在shipping之后.
This is the only rule I add. Without this rule, tax_shipping is sorted after shipping.
<shippingprotectiontax>
<class>n98_shippingprotection/quote_address_total_shippingprotectionTax</class>
<after>subtotal,discount,shipping,tax</after>
<before>grand_total</before>
</shippingprotectiontax>
下面，我将usort调用返回的排序数组粘贴到Mage_Sales_Model_Quote_Address_Total_Collector::_getSortedCollectorCodes()
对于没有安装Magento的用户，代码如下:
Below I paste the sorted array that is returned by the usort call in Mage_Sales_Model_Quote_Address_Total_Collector::_getSortedCollectorCodes()
For those who do not have a Magento installation, the code is like this:
/**
* uasort callback function
*
* @param array $a
* @param array $b
* @return int
*/
protected function _compareTotals($a, $b)
{
$aCode = $a['_code'];
$bCode = $b['_code'];
if (in_array($aCode, $b['after']) || in_array($bCode, $a['before'])) {
$res = -1;
} elseif (in_array($bCode, $a['after']) || in_array($aCode, $b['before'])) {
$res = 1;
} else {
$res = 0;
}
return $res;
}
protected function _getSortedCollectorCodes()
{
...
uasort($configArray, array($this, '_compareTotals'));
Mage::log('Sorted:');
// this produces the output below
$loginfo = "";
foreach($configArray as $code=>$data) {
$loginfo .= "$code\n";
$loginfo .= "after: ".implode(',',$data['after'])."\n";
$loginfo .= "before: ".implode(',',$data['before'])."\n";
$loginfo .= "\n";
}
Mage::log($loginfo);
...

在Vinai回答之后，我添加了更多调试代码
After Vinai's answer I added more debug code
$fp = fopen('/tmp/dotfile','w');
fwrite($fp,"digraph TotalOrder\n");
fwrite($fp,"{\n");
foreach($configArray as $code=>$data) {
$_code = $data['_code'];
foreach($data['before'] as $beforeCode) {
fwrite($fp,"$beforeCode -> $_code;\n");
}
foreach($data['after'] as $afterCode) {
fwrite($fp,"$_code -> $afterCode;\n");
}
}
fwrite($fp,"}\n");
fclose($fp);
并使用graphviz可视化:dot -Tpng dotfile > viz.png.那是第一次尝试的结果.排序后调用.
And visualized it with graphviz: dot -Tpng dotfile > viz.png. That's the result of the first try. Called after the sorting.
我认为这毫无用处.
因此，在合并after/before条目之前，我对阵列进行了可视化处理. (在$configArray = $this->_modelsConfig;之后)
So I made a visualization of the array before merging the after/before entries. (right after $configArray = $this->_modelsConfig;)
没有我的shippingprotectiontax条目就是这样:
This is it without my shippingprotectiontax entry:
这是我的shippingprotectiontax条目:
我看不到任何明显的矛盾.
I do not see any clear contradictions.

Update: Magento Bug Ticket: https://jira.magento.com/browse/MCACE-129
推荐答案
最后，这是我针对此问题的补丁.
So finally, here is my patch for this issue.
它实现了Vinai建议的拓扑排序.
It implements topological sorting as suggested by Vinai.
- 将
app/code/core/Mage/Sales/Model/Config/Ordered.php复制到app/code/local/Mage/Sales/Model/Config/Ordered.php - 将修补程序的内容保存到文件
total-sorting.patch并调用patch -p0 app/code/local/Mage/Sales/Model/Config/Ordered.php
- Copy
app/code/core/Mage/Sales/Model/Config/Ordered.phptoapp/code/local/Mage/Sales/Model/Config/Ordered.php - Save the contents of the patch to a file
total-sorting.patchand callpatch -p0 app/code/local/Mage/Sales/Model/Config/Ordered.php
如果要升级，请确保重新应用这些步骤.
In case of upgrades make sure to re-apply these steps.
该补丁已通过测试，可与Magento 1.7.0.2一起使用
