问题描述
我以前写过很多模块,但由于某种原因,我的运输模块不会覆盖现有的万磁王运输方式.允许吗?我在这里错过了什么?模块名称显示在配置区域的高级选项卡中,因此它正在加载,但什么也没有发生.任何提示?
I've written many many modules before but for some reason my shipping module won't override an exsiting Magneto shipping method. Is that allowed? What am I missing here? The module name shows up in the advanced tab of the configuration area, so it's getting loaded, but nothing is happening. Any hints?

推荐答案
在仔细研究这个之后,我发现覆盖传送控制器的唯一方法是在本地代码文件夹.然后我基本上可以调整代码.
After working through this one a bit, I found that the only way to override the shipping controller was to make a duplicate of the file (and directory structure) in the local code folder. Then I could basically tweak the code.
不知道为什么 Magento 似乎不允许标准覆盖这些传送功能,但至少有一个解决方法.
Not sure why Magento doesn't seem to allow the standard overriding of these shipping functions, but a least there is a work around.
